Very often, car owners face the question: is it worth changing the engine from gasoline to diesel in a car? Answering "yes" to it immediately raises many other questions: from which diesel engine is better, ending with where to get spare parts. Let's try to understand these points.
Diesel: advantages
Perhaps the main advantage of this type of engine is, of course, savings. In conditions modern world when prices are rising, including for gasoline, changing the engine means winning on fuel. First, a diesel engine always consumes less fuel than a gasoline-powered engine. On average, this figure is about thirty percent. And the fuel itself is almost ten percent cheaper than gasoline - again, this is the average for the country.
The efficiency of a diesel engine is about forty percent - this is if the engine is not new. And more powerful units, in which there is intermediate cooling and turbocharging, in general, give an efficiency of more than fifty percent.
The resource of a diesel engine is almost one and a half times more than that of gasoline counterparts.
These are the main positive aspects of engines of this type. Now to the cons.
Diesel: disadvantages
Naturally, a diesel engine is not perfect. With all its positive qualities, you can find as many (if not more) minuses:
- Firstly, the weight of an engine of such a plan is much greater than that of a gasoline-powered one. In the case of repair, you will have to tinker with installation, carrying and other unpleasant things.
- Secondly, a car with a diesel already installed will be more expensive than the exact same one, but running on gasoline. Even if you decide to buy the engine separately in order to install it on an existing car, it will cost you a pretty penny.
- Point three, by the way, is very relevant in the conditions of our country, especially for car owners in the Siberian expanses: diesel fuel is very sensitive to low temperatures. There is even a special winter fuel to minimize the risk of fuel freezing.
Actually, these are perhaps the main disadvantages of this fuel. And now, let's specifically discuss the diesel engine for UAZ of various types.
For what?
By installing a diesel engine in a UAZ, of course, the car owner pursues not only the goal of saving fuel costs. Diesel is power, solidity, so to speak. After all, the first thing that comes to mind when they call the UAZ brand is cross-country ability. Indeed, what kind of car do we most often imagine when it comes to moving across rough terrain, among swamps, forests, streams? What kind of engine pushes the car, allowing it to overcome any obstacles? Which of the units is popular, and which is already outdated? Before the car owner wonders how to put a diesel engine on a UAZ, he will first think about what kind of engine is needed.
Diesel for "loaf"
Let's figure out what kind of diesel engine is usually installed on the UAZ-452 ("loaf" - among the people). Another name for such a car is a "tablet". Below will be presented those engines that, according to experts and motorists, are most suitable for such a car.
The Peugeot Indenor engine is very much appreciated by drivers - it was installed on the Ford Sierra already in the distant eighties. But despite its age, it is this engine that is considered the most suitable and reliable for a "loaf". The volume of the engine is 2.3 liters. If this is not enough, then you can put the same one, but from Ford Scorpio and Ford Transit cars of the same years - there is a volume of 0.2 liters more, and if you try, you can even find turbocharged engines. By weight, they are slightly more than their "colleagues" running on gasoline, and install them knowing person also quite easy.
Another popular engine for a "loaf" is called "diesels" from "Mercedes", whose volume is: 2.2, 2.4 and 3 liters. It is advised to pay attention to the engines that were produced in the late seventies. But it’s more difficult to install them - more due to the fact that the oil filter is very poorly designed and is located in front and at the very bottom. If the car is moving over rough terrain, all the bumps and stumps will "butt" into the filter. Therefore, it is necessary to put additional protection in order to keep the engine safe and sound.
A diesel engine for UAZ from the Isuzu company, model 4-JJ-2, is highly recommended. Its volume is 3.1 liters, moreover, it has a turbocharger. The main problem with such an engine is that it is almost impossible to get it, especially in Russia.
And the last on this list will be Toyota Hiat, 2 liters. According to many - the most reliable, high-quality, absolutely no hassle. It is quite easy to buy, you can install it without any problems and maintain it without straining, because there are also enough spare parts for it. They only advise buying those engines that were produced before the end of the eighties, because there are all parts made of cast iron, and on later engines some of the parts are made of aluminum.
UAZ "Patriot" with a diesel engine
We talked about the "pill", now about the "Patriot". Initially, the cars were equipped with an Iveco engine of Italian origin. Its indicators are as follows: 2.3 liters - volume, 19-13 liters per hundred kilometers - consumption along the highway. But they did not put it on for long: apparently they decided that if the "Patriot", then the components should all be domestic. Switched to diesel ZMZ.
The ZMZ diesel engine on the UAZ "Patriot" was clearly out of place, as many car owners believe. The engine for such a large car is clearly weak, in some places it frankly "didn't pull" off-road, as UAZ drivers say. Of course, a diesel engine, for example, ZMZ 51432, is much better than its "gasoline counterpart", but still - not that.
They found a way out that was not easy to execute, but reliable: to install the same engine from Iveco, which was once factory for this car. Again, the most praised is the F1A, whose volume is 2.3 liters and the power is 116 hp. With. If a Korean Daimos gearbox is also paired with it, then it turns out just great. The same engines are quietly put on the UAZ "Hunter". The only thing is that you have to tinker and it costs a lot of money too.
What diesel engines are put on the UAZ "goat"?
For a UAZ "nosy" they advise the opposite - it is a diesel engine from the ZMZ series. For example, ZMZ-406, ZMZ-405 or ZMZ-409. Of course, you will have to dig into almost everything: fasteners, exhaust and fuel systems, it will be necessary to redo the clutch housing and change the wiring diagram. But this is the most budgetary and most practical option.
If the engine is installed from the Mercedes company, then the most suitable for such a rearrangement are OM616 and OM617. They are called very reliable, already time-tested and quite economical.
If you install an engine from Toyota, then the 1KZ-TE unit is best suited for this role. When you install it in the car, of course, you will have to tinker. But you do not need to touch the body. But diesel 2 LT from the same company is called the easiest to install. It is only necessary to carve a spacer under the front cardan about two centimeters and push the radiator just a little forward.
Peculiarities
When installing a diesel engine on a UAZ, you may encounter some nuances. Firstly, when a diesel is attached, it is almost always necessary to redo the attachment points, the pallet, you need to digest the brackets or, in general, add new ones. Secondly, do not ignore the fuel supply and cooling systems of the car engine. All this will also have to be improved. More changes will affect electrical equipment, which will have to be adjusted to the new engine. The scope of tasks will depend on what type of diesel engine you decide to put on the car.
Another problem faced when remodeling cars is noise. The diesel engine is quite loud at work, so you should take care of soundproofing, otherwise you will be forced to drive to not very pleasant music. Also, the car needs vibration isolation - compared to gasoline engines, "diesel" produces a very large vibration. This applies even to new, no doubt, modified models.
More specifically about ZMZ
Engines of this kind have already been discussed above. Many car owners call the main disadvantage of such an engine low power. Indeed, for cars of the UAZ brand, with a rather large weight and high requirements for cross-country ability, the engine is considered a burden. And its resource, on average, is 100,000-150,000 kilometers, which is not much. Despite the fact that spare parts for it can be found in abundance in any parts store, they are all not of very good quality. Which also does not make good advertising for the engine.
But there are pluses: they note that it is very easy to install and repair in the event of a breakdown, literally in the field. Not capricious about the weather. A simple hard worker, without foppery, which fits any UAZ car.
Conclusion: the pros and cons of a UAZ diesel
Having acquired diesel engines, UAZ vehicles began to surf the expanses of Russia with even greater energy. But seriously, a qualitatively converted UAZ simply has no competition all over the world as an SUV. By the words "qualitatively altered", of course, we mean not a factory assembly, but an already pumped car - with a new engine, securely tightened bolts, and proven electronics. Fortunately, car owners are usually skilled people. Therefore, let's generalize: it's a good idea to put diesel on UAZ. Reviews, in any case, on any forum of motorists are mostly positive. Of course, there are disputes about which engine is better to put on a car, but this is a matter of practice. Whether it's UAZ "Hunter" or "goat" - if the car is in skillful hands, then it obviously will not become worse from improvements.
There are also disadvantages - again, according to the reviews of the owners. The weight of the car has become more - albeit just a little, but still the heavy engine makes itself felt. And also - the price. Still, changing the engine, especially in our economic situation, is not easy.
Almost everyone who prefers to drive UAZs had to think about how to make a diesel engine installation under the hood of their SUVs. First of all, the installation of a diesel engine in the UAZ would make it possible to save on fuel.
The UAZ engine, which is filled with diesel, will require less fuel consumption due to the increased efficiency. In addition, the diesel engine on the UAZ will be more torquey than the one on gasoline. These are the devices that will put out more power at low RPMs.
It is now quite easy to make a choice of an engine for a UAZ. According to the theory, specialists can fit all sorts of powerful units under the hood of this car. Any difficulty in the process of this lies necessarily in the cost and availability in order to install a new engine.
It is necessary to make a choice of a diesel-fueled engine for UAZ in accordance with certain criteria. For example, it is necessary to take into account the magnitude of its torque. For UAZ, low-speed engines, such as ZMZ-402, ZMZ-406 and the like, may be suitable. In the opposite version, it will be necessary to redo the gearbox and axles.
What to put on UAZ
It is recommended not to do experiments, performing the installation of an engine that has not been tested in practice, but to use the experience of specialists. For the entire period of time during which UAZs exist, they tried to install different engines, including diesel engines. Of these, there are those that will perfectly fit this machine without significant modification. So, for example, for an Oise of the “Loaf” type, an engine from a Ford can perfectly fit, and when to be more precise, then from a Siera. The gold of this unit is 2.4 liters, and their production was carried out within 1984-1990. The indisputable advantage of these engines is the state of its reliability and long-term operation. American made engines can last three to four times longer than domestically made ones. Diesel engines from Mercedes are even more popular for installation on UAZs. Naturally, who does not have the desire to make a Mercedes out of their modest UAZ?
In order to make a replacement, they prefer for the most part engines running on diesel from 2 to 2.4 liters. At the same time, according to the design, engines from Mercedes, which were produced during 1980-1984, are suitable for the change. But quite often, Mercedes engines of a similar type have rather serious vulnerabilities, and certainly an oil-type filter. It is located in the engine from below and can simply be damaged when passing through difficult sections. But this is easily solved by installing additional protection.
How to install a diesel engine on a UAZ: features You can install a diesel engine on a car, as in specialized auto repair shops, or install it on a UAZ yourself. The most basic thing during the installation of a new engine is connecting it to the gearbox. For these purposes, special adapters are needed.
When there were no difficulties with this, then it is further necessary to determine how the engine will be screwed to the car frame. Here you need to contact the welders for help, because you need to digest the brackets or add new ones. In the future, you just need to connect all the engine controls, and, of course, make its settings. When the engine is with an injector, then without the advice of specialists in electronic business it is hardly possible. When the engine is placed on the UAZ, the car must be re-registered with the police, where the engine change must be confirmed. Otherwise, the car may simply be confiscated during the Gaya stop. How to highlight the fact that putting a diesel engine on the UAZ not on its own can result in a significant additional amount. In general, in more options it will be worth it.
Having made a do-it-yourself UAZ engine change, UAZ owners may not remember about failures, sneezing or lack of traction at low revs. Further, the car will bring joy with not very significant fuel consumption due to the higher efficiency of a foreign-made diesel engine.
UAZ diesel nuances UAZs have always been and will remain cars that are designed to be operated by real men. They were able to get a recommendation for excellent off-road vehicles belonging to the budget class, which are not inferior in terms of cross-country ability to similar ones produced abroad. Spare parts for them are not very expensive and you can just buy them, but not everything is as simple as it might seem at first.
Even Richard Diesel argued that for the manufacture of parts for engines, it is necessary to work accurately, and in Russia the work of mechanics did not reach a high level. His thoughts turned into a kind of karma.
Regardless of the colossal progress of Russian designers, the final state of the quality of the product leaves to be the best. This also applies to UAZs. Without a doubt, now you can also meet the old models of "tablets" and "bobbies" that have traveled more than a hundred kilometers. But technology is developing with progress, diesel engines are regularly improved and improve their performance. Now in the market of spare parts for cars, you can see products from different manufacturers and even buy a diesel engine with two cylinders, which not so long ago was a product that belonged to the rare category.
It is no secret that, as for UAZ vehicles used for commercial purposes, for budget purposes, and others that operate under harsh conditions, a diesel engine will be the maximum. It will be more reliable, economical, unpretentious and more durable than those on gasoline.
Therefore, the topic of changing the engine from gasoline to diesel will not raise doubts among most fans of cars of this Russian-made brand. It remains only to choose and purchase a diesel engine for the UAZ, but difficulties can begin here, because you definitely cannot know what to prefer.
The cost for new UAZ diesels is slightly more than similar, used engines from the automotive industry from Asia.
More car enthusiasts will choose Japanese manufacturers and this is understandable.
Engines produced in this country are more reliable than Russian ones. Also, due to the not very large size and the similarity of the design, they can simply be “undermined” for the design of the UAZ. And the market offers foreign models a large number of for every taste and color.
A car with such an engine will be significantly different from the same one with a gasoline engine. It will have some traction of a steam locomotive and a temper that is difficult to keep. What else is needed for hard workers Ulyanovsk? It is clear that when high speed is required from a car, then it is necessary to use a gasoline engine, and when an SUV is required that is not afraid of dirt and rough terrain, then a diesel engine will be an excellent purchase.
Advantages of Diesel Engines A diesel engine, compared to a gasoline engine, will have many advantages that it owes to its ever-increasing popularity. Now, with the ubiquity of electronic diagnostic tools and dedicated equipment, high quality diesel maintenance has become widely available, making it possible to keep diesel engines in excellent working order for long, cost-free overhauls. Therefore, an increasing number of car enthusiasts prefer a diesel engine.
One of the main advantages of a diesel engine is its economy. A diesel engine has an efficiency factor of approximately twice that of a gasoline engine, naturally it will consume less fuel. Another advantage of diesel engines is the high torque value even at low speeds. This will press down on the car the property of flexibility when driving, making it possible to move off with ease and overcome any obstacle.
Due to the presence of optimal torque in a significant range of revolutions, diesel engine power is used with a much greater effect than engine power, which is on gasoline. The most common models In UAZ cars, even now there is no tolerable and non-diesel engine that would be able to further reveal the excellent potential of the Ulyanovsk all-terrain vehicle.
In the first place is the diesel unit from Ford, and specifically the Siera model with a capacity of 2.4 liters, produced from 1984 to 1990. Another model is the Ford Scorpion, which has a volume of two and a half liters, which was produced from 1984 to 1990. For your information, engines from models of cars made in America are able to serve for a long time. The two proposed diesel-type engines are ideally suited for replacement with a regular one that runs on gasoline, has a UAZ loaf. It will not be difficult to adjust these engines, both for specialists with extensive experience and for people from the people.
Another brand of cars that could find wide distribution in the UAZ Loaf is diesel from Mercedes. Powerful units with a volume of 2 and 2.4 liters, which were produced from 1980 to 1984. The engine plant, which is part of the Sollers concern, began to supply the first engine on the ZMZ-51432 Euro-4 diesel engine to the Ulyanovsk automobile plant in order to work out the technology for assembling the car on stream, the press service of RIA reported. Oise with a diesel engine ZMZ-51432 (2.2 liters).
A small displacement engine belonging to the new generation ZMZ-51432 (2.2 liters) with a Common Rail fuel supply system was able to pass qualification experiments in order to confirm the declared characteristics.
What cars will they be installed on? This engine will be produced in various versions to complete the entire line of UAZ vehicles for the transport of passengers and goods. The diesel engines ZMZ-514 "Euro-3" now produced on the territory of the plant are supplied to the configuration " UAZ Hunter” and the so-called “loaf”.
The latest developments in diesel "Euro-4; used more than a hundred parts and assemblies in the original design.
What is typical for diesel?
The optimal value of engine power has been increased from ninety-seven horses at four thousand revolutions per minute to one hundred and fourteen horses. At three and a half thousand revolutions, the amount of torque is from twenty-three kilograms of forces at 1.8 thousand revolutions for a minute to twenty-seven kilograms of forces per meter. The plant produces more than eighty engines with various modifications with a volume for operation from 2.2 liters to 4.67 liters, which comply with modern environmental standards, for cars with buses of three Russian companies - UAZ OJSC, Pavlovsky Bus OJSC and OJSC "GAS".
UAZ, running on gasoline, in comparison with how diesel came out as a supercar. A car from the Volga region with sixteen valves can pull more briskly, and its working interval is wider. Therefore, the “steps” between gears are not felt that way. But any switching again forces us to remember the experts of Arzamas, and the development of the pace during acceleration without hope can be lost by making convulsive attempts when placing the necessary stage in the bowels of a harmful box.
In addition, UAZ is an infrequent option when the lack of dynamic properties is only beneficial. After eighty kilometers per hour, the Hunter will be in a "floating state" on the road surface, needing constant alignment, and even on not very large bumps will begin to jump in different directions. The car absolutely does not recognize insignificant deviations of the steering wheel, and in response to turns of the steering wheel, which have a deep roll, it will shy to the side. This will not only be not entirely pleasant, but will also become dangerous. So it’s close to skidding, and capsizing will occur.
Sample UAZ Patriot diesel was able to arouse a lot of interest. In general, the main advantage of a diesel engine is traditionally considered to be the traction of a steam locomotive at low speeds and low fuel consumption.
For drivers who are accustomed to moving around on a gasoline engine, the sensations are not quite ordinary. They give the impression of a machine that has better dynamics. However, can this affect the state of driving quality? In reality, no.
In general, motorists need the amount of torque on the wheels from the car, and what number of revolutions the engine makes does not matter (apart from the emotional state of the driver).
There is only a condition: the right choice of gear ratios. In addition, diesel engines have a worse adaptation factor than gasoline engines.
It is not worth making a description of this concept in detail, you can only add that for drivers it will mean a more feasible gear shift (when the gearbox has a device with a manual mechanism). Similarly, diesel engines, as usual, have worse mass dimensions. For example, the Iveco diesel power is lower than that of the ZMZ-409, but at the same time it is heavier. There is a rather significant negative point: any diesel engine with a Common rail power system will make more noise than gasoline engines. Any gasoline engine will make a rattling sound. The fact that diesel engines will consume less fuel is not disputed. However, will they spend less money? Not every time. You can calculate the difference in the price of one kilometer of road for a UAZ Patriot with an Iveco diesel engine and a gasoline engine.
A patriot on a diesel engine will spend ten liters of fuel in the city at nineteen rubles and fifty kopecks per liter. That is 1.95 rubles per kilometer. The one that runs on gasoline - thirteen liters at twenty-two rubles. The result is 2.86 rubles per kilometer. This means that the fuel economy of a diesel engine will be ninety-one kopecks per kilometer. Fairly significant savings.
Conclusion - there are many advantages of UAZ diesel, there are also disadvantages, each driver should choose at his own discretion!
The UAZ Patriot SUV is a car for drivers who prefer driving not only on asphalt, but also on rough terrain. The engineers of the Ulyanovsk plant have created a real steel horse designed for off-road use. Sitting in the cabin, you can feel absolutely comfortable, but over time you realize that something is missing. This something is not only to change the appearance of the car, but also to upgrade the engine. If chip tuning is a passive form of improving technical performance, then replacing the engine is an essential way to modernize a car. It is to replace the internal combustion engine of the ZMZ-409 brand installed on an SUV that will be discussed today. Consider what types of engines of domestic and foreign production can be installed on the UAZ Patriot.
What kind of foreign engine can be put on a domestic-made SUV in order to increase the technical performance of the Patriot? The first option is to install a motor from a Toyota Surf car. In addition, to install a new engine, you do not need to have engineering knowledge, for this you simply need to purchase a unit. There are some features for installing a motor from Toyota Surf on a UAZ. Let's look at them briefly:
- The mounts of the standard motor must be moved a few centimeters forward and the angle of inclination changed. The angle of inclination is needed in order to place pillows that eliminate vibrations.
- Before installing the engine, it is also necessary to remove the power steering bracket. It will rest against the timing, so problems may arise.
- The radiator remains stock. He does his job very well. It can completely provide cooling for a Japanese-made engine.
- The air filter is located on the left side of the engine compartment.
- It is also recommended to replace the exhaust system, that is, use the Japanese version, which is more reliable.
After replacement, the following improvements can be found:
- Fuel consumption will be reduced.
- Disappear problems with razdatkoy and checkpoint.
- Improved dynamics.
Who else can install the engine on the UAZ Patriot? In addition to the Toyota engine, a domestic engine from the GAZ-53, better known as the V8, can also be installed on a car.
V8 engine
The well-known GAZ-53 truck with a V8 engine, which means eight cylinders, is still in use today. The car has an excellent engine that can be installed on the UAZ Patriot. The V8 engine from the GAZ-53 has a power equal to 115 hp. and a lot of torque. In addition, this unit perfectly takes the place of the standard SUV engine.
To fulfill the dream of installing a V8 engine in your car, you should replace the exhaust system, transfer case and gearbox. After installing the V8 engine, the power of an SUV is felt, which is ready to overcome difficult off-road and obstacles, but to pass through swamps, ponds and snowdrifts. With the V8 engine from the GAZ-53, the SUV is not afraid of high-speed traffic on the highway. Below is a video showing a UAZ Patriot with a V8 engine from GAZon-53 installed.
After watching the video, you understand what an 8-cylinder engine from a Soviet mid-tonner is. With the new V8 engine, Patr runs a lot louder, which is exactly how it should be. Domestic-made engines are famous for their endurance and efficiency, therefore, by installing such a V8 engine, you can forever forget about a standard engine, since you will no longer want to return it.
GAZonovsky engine is more powerful than the regular one from the Patriot. But its main advantage is reliability, which cannot be said about modern motors.
Engine from Nissan
If there is a desire and finances, then a more powerful engine can be installed on the UAZ Patriot than the GAZ-53. This is the Nissan Kid 32 engine from Galagrin. The power of such a unit is approximately 150 hp, which is more than necessary. It should be noted that this unit from Nissan Kid 32 is diesel. 150 HP also relevant for an electronically controlled unit. With manual control, power is reduced to 135 horses.
Of course, no one says that the Nissan Kid 32 engine is installed new, you can put a contract one. The reason is that new units must comply with the Euro-4 environmental standard.
After replacing the standard engine with a Nissan Kid 32, the UAZ Patriot SUV is characterized by the following parameters:
- Power increase. Now an SUV can not only get out of any trouble, but also pull out its own kind.
- Consumption increases, which is justified by an increase in power.
To install the Nissan Kid 32 engine on a Patriot, a suspension lift will be required for the latter.
Cummins
In conclusion, I would like to note the advantages of the Cummins engine, which are also great for a new generation SUV. First of all, it should be noted that Cummins is exclusively engaged in the production of diesel engines, famous for their durability, economy and safety.
Cummins engines are installed in Gazelle cars. Cummins is suitable for those types of vehicles that are designed for off-road and asphalt conditions. Therefore, if you often operate your car on mixed types of roads, then Cummins will be the best solution.
Summing up, it should be noted that today we have reviewed superficially the types of engines, both domestic and imported, that can be put on your SUV. In many cases, of course, improvements are required, but nevertheless, the replacement is done at home. Which motor to put: imported or domestic - it's up to you, the main thing is that the chosen option fully meets your needs.
You can check your CBM and reduce it if needed!
Today, the popularity of diesel engines is growing every year. Even new cars in 25% of cases are equipped with diesel engines, although 10 years ago only every 10 car was produced this way. The reasons for the growth of their popularity are strict requirements for the environmental friendliness of the engine, the constant increase in gasoline prices. At the same time, a diesel engine can even be fueled with biofuel - rapeseed.
Advantages of a diesel engine over a gasoline engine
Today, the biggest advantage of a diesel engine over a gasoline one is its efficiency. Not only is the cost of diesel fuel much less than gasoline, but the engine itself is also used in an economical mode. The reason for this is the different scheme of operation with different fuels.
In a gasoline engine, fuel vapors are ignited by spark plugs, which produce an electrical spark. In diesel, the vapors are ignited by the high temperature of the air that has been pre-compressed. Accordingly, in the latter case, there are no spark plugs, but there are glow plugs. The design of the motor itself is more durable, since its massive parts must constantly withstand detonation. Therefore, this design lasts longer.
In short, The diesel engine has the following advantages over the gasoline engine:
low fuel cost (by 10-15%);
Low fuel consumption (by 30-40%);
The absence of an ignition system makes the engine design simpler, easier to operate, and it also gives good traction at low revs;
More massive parts are fastened more rigidly, and therefore the engine can withstand longer without major repairs (up to 1 million kilometers);
Gives low CO2 emissions, smoke and soot only come from faulty engines.
Interesting! The diesel engine also has its drawbacks. It takes longer to warm up, and with a manual transmission, you have to switch it more often. Low-quality fuel quickly disables injectors, and maintenance costs 15-20% more than gasoline.
Diesel engines for UAZ "Loaf"
The domestic all-terrain vehicle UAZ "Tabletka" or "Loaf" has gained popularity for its reliability and excellent driving performance. It is taken to move along rural roads, in hard-to-reach places, where they go hunting or fishing. But few people know that in addition to the gasoline engine, the Loaf is produced with diesel engine. True, such cars were made exclusively on government orders for military needs. Serial public cars were exclusively gasoline.
The fact that Loafs also run on diesel prompted many craftsmen to the idea of replacing the car's native engine with a diesel one. True, it is not always possible to find exactly the one that is provided for this model of machine. In this case, you can use units from other cars.
So, if you didn’t get the diesel “Loaf” from the factory, you can use these engines:
1. Engine from "Ford Sierra" 1984-1990 for 2.4 liters or "Ford Scorpio" the same years of production for 2.5 liters. They are so suitable for UAZ that even an inexperienced car mechanic can fit them.
2. Engine from "Mercedes" 1980-1984 with a volume of 2 and 2.4 liters. But such a detail will make your Loaf a rather expensive car.
Note!The oil filter in the Mercedes engine is located in its lower part towards the movement. This is considered not only an impractical arrangement, but also very dangerous when driving off-road. Therefore, in this case, it is recommended to install additional protection on the engine.
3. A series of Isuzu 4JG2 diesel engines with a volume of as much as 3.1 liters with a turbocharger. True, it is extremely difficult to find such an engine.
4. Xayc 2L engine from Toyota with a volume of 2.4 liters. In addition to reliability and excellent technical characteristics, it is distinguished by availability on the market.
In addition to engines from other cars, you can find separately manufactured units.
Ideal for UAZ fit:
1. Motor "Andoria" on UAZ, which has been manufactured at the Polish state plant of the same name since 1945. It produces atmospheric units and supercharged. Some models of its diesel engines are equipped with fuel equipment from the German company Bosh, others - from the Czech Motorpal. But all of them are made according to European standards, they have a lot of quality certificates from European organizations.
created specifically for UAZ weighing up to 3.5 thousand kg and a 4x4 wheel arrangement. It works perfectly at temperatures from -45°С to +40°С and even at air dust content up to 1 g/m3. It proved to be excellent when working at an altitude of up to 4,000 m above sea level. At the moment, there are two models on the market: ZMZ-51432.10 CRS, equipped with a Common Rail fuel supply system, and ZMZ-5143.10 with a mechanical injection pump.
3. ZMZ 5148 diesel, which is produced at OAO Zavolzhsky Motor Plant. Electronic systems fuel supply for it is developed and supplied by the German concern Siemens. The units comply with the requirements of Euro-3 and Euro-4 standards.
Note! Just one refueling of low-quality fuel can disable a diesel engine. Moisture is also a danger: both in the canister and in the environment.
How to install a diesel engine on the UAZ "Loaf"
Having chosen the right engine, you need to figure out how to install it on your car. To do this, stock up on a special adapter that will connect the gearbox to the clutch. Improvements will also require the car's power system and side electrics.
Install the diesel engine in the following sequence:
1. Completely remove the "native" gasoline unit, then cut off the brackets with a grinder, and weld the necessary ones in their place.
2.
Cut the brackets from the frame and hang the diesel engine on the hoist. Make sure that the diesel bolt (ratchet) is pointed clearly at the hole in the crank located in the frame.
3. If necessary, put pillows on the engine. Even if they are on a new diesel engine, it is better to rearrange the native UAZ ones. True, they must be installed so that there is no unnecessary vibration during the ride.
Interesting!It is much easier to install a diesel engine without a head on a UAZ.
4. Then the exhaust pipe is redone, the pallet is cut off from the new diesel engine, and the UAZ one is welded instead. The seams must be cleaned, and then treated with cold welding.
5. Now you can install the engine and crankcase, and then start adjusting the clutch. The latter can also be used "native". It will fit in three holes, the rest must be drilled and threaded.
6.
Under the input shaft, it is necessary to machine a bronze bushing instead of a bearing. Do not use the UAZ crankshaft for this. We recommend purchasing two bearings 7 mm thick and 35x17 in size. They must be inserted one after the other into the machined U-shaped sleeve.
Some experts believe that after such manipulations, the UAZ "Loaf" with a diesel engine requires the installation of sound insulation under the hood - the diesel engine runs a little louder than the gasoline unit. Of the improvements, it will still be necessary to make oil sensors under the fitting, as well as shorten the cooling fan blades a little.
The diesel engine is superior to the gasoline engine in many ways, although it also has its drawbacks. UAZ "Loaf" can work with both one and the other unit. If you do not come across a car with a factory diesel, you can easily install it yourself. To do this, either a special motor for UAZ is taken, or a diesel unit from a car of another brand.
This the best option for a domestic SUV. It is worth noting that with the reduced motor, the car becomes passable and stable. Later in the article we will talk about how exactly the engine is changed.
How to install on UAZ V8 (engine)
UAZ "Patriot", like other UAZs, requires additional "file processing" immediately after purchase. True, a large number of new car owners of a post-Soviet car are limited to a simple broach of all elements and the elimination of multiple "jambs" that are available in the factory assembly. But the most important problem of this car is the lack of a powerful diesel engine in the engine lineup. And what to change it to? Turbocharged Cummins diesel in this case is considered an excellent option.
As soon as the iron curtain collapsed, and supported foreign cars began to arrive in our country, self-taught people appeared in the Russian Federation who wanted to install an imported engine on, in general, SUVs, or rather, on the UAZ V8. "Patriotism" at that time did not even smell, since the victims of many, sometimes stupid, attempts were various UAZs.
Their engine compartments were occupied by various engines, not only foreign ones, but also from Soviet trucks and, of course, buses - UAZ with a PAZ engine or an engine from GAZ 66th model - it was natural.
Popular engines for UAZ
The most popular were (and are considered to this day) diesel engines from the Japanese manufacturer - Nissan, Isuzu, Toyota. And at the first Moscow automobile shows, a variety of private manufacturers showed samples with these engines.
After some time, the number of experiments grew into quality, they created accurate, well-established copies of the V8 “dump” engines on the UAZ-469, and the company created an updated SUV brand. The comfortable and roomy "Patriot" was equipped (except for the domestic "gasoline") with an Italian Iveco turbocharged diesel engine. But this did not last long - the Italian motor was removed, equipping the car with the Russian diesel unit ZMZ-51432.
In our country, the UAZ "Hunter" is equipped with a V8 engine
The well-known domestic automotive blogger aGademeG showed in his video a special version of the UAZ Hunter SUV with a V8 engine. It was prepared by order of familiar automotive mechanics. An 8-cylinder engine from a Japanese manufacturer was installed in this car, which has a power of more than 300 hp. With.
Thanks to this engine, a Russian SUV can accelerate to 100 km/h in 7 seconds. These indicators gave him the opportunity to compete even with sports cars. During the creation of the sports version of the UAZ Hunter, they took an old SUV, and the engine space was occupied by an 8-cylinder engine from the Toyota concern.
In the course of the improvement, automotive mechanics installed the maximum revving engine in the UAZ, thereby solving problems with the clutch, gearbox and shock absorbers (since they could break at high engine speeds). And yet, all obstacles have been resolved, and this car has left for testing near St. Petersburg. It is worth noting that along with the engine from Toyota, the improved Hunter combined an automatic transmission, and the car itself became rear-wheel drive.
Installation instructions ZMZ V8
There are known attempts to install a V8 on a UAZ. This seems quite acceptable to car owners. Since motors from gas engines of the 53rd or 66th or PAZ can be installed on a UAZ. Such engines are found in conservation and simply repaired. But there are also some:
- One of the main ones is fuel consumption. There are many records about the fact that it is 10-12 liters on the road.
- The next incomprehensible situation is heating. How to cool this car, on this moment there are few answers. Many motorists talk about the use of conventional copper cooling in UAZ.
What you need to do to install V8 engine on UAZ 469?
- Drill holes in clutch cover.
- Remove the bells and drill holes in them for the UAZ V8.
- Next, cut the thread for the studs.
- It is advisable to cut down the front motor mounts and dock the motor with the gearbox.
- Before installing a new engine, remove the radiator and dismantle the old engine.
All motorists point out that after installing the ZMZ V8 on a UAZ, the engine works several times better than the standard one - it is more powerful, more practical and several times more resourceful.
What does the installation of a V8 engine on a UAZ "Patriot" entail?
The well-known 53rd GAZ truck with a V8 engine (the latter has 8 cylinders) is still used today. This is a car with an excellent engine, which is also installed on the UAZ "Patriot". V8 engine from the 53rd GAZ, whose power is 115 horsepower, with good Hm. And, on top of that, it fits perfectly in place of the usual SUV unit.
To install a V8 on a UAZ "Patriot", you need to replace the exhaust system, "razdatka" and gearbox. After the V8 engine appears, the power of the car is felt, which is able to overcome not only off-road and various obstacles, but also snow cover. With the V8 unit from the 53rd GAZ, the car is also capable of high-speed progress along the road. The reviews available about the installation on the UAZ V8 indicate that the car is able to move on almost any terrain.
True, with this engine (V8), the UAZ "Patriot" works a little louder, but, in principle, it should be so. In general, Russian-made engines are known for their practicality and efficiency, and therefore, having installed the described V8 unit, you can generally forget about the standard UAZ engine, since there is no need to return the standard installation.
Advantages and disadvantages of the car after installing the V8 on the UAZ
The installation of the engine has both positive and negative sides. We will list them. Advantages available:
- The power, together with the speed on the snow cover, allows the car to move much better.
- Works a hundred times nicer than standard, while there is no vibration.
- On asphalt, the car shows great power.
There are also some disadvantages:
- Resonators from the 52nd GAZ are not suitable, so silencers should be installed.
- Loud noise at high rpm.
- The bridge may hit the pallet. But this, of course, is not fatal, and after installing shock absorbers, it generally ceases to be a problem.
In general, the reviews of car owners who have changed the engine are in favor of installing a V8 on a UAZ.
Tuning options for this car
UAZ tuning needs to be started with a technical component - the car's patency will depend on this. You can buy a three-liter engine. This unit perfectly copes with all duties, it does not need forcing. It is also advisable to equip the motor with iridium candles - they improve its performance. And for greater effect, you can bore the cylinders. Be sure to pay attention to how the unit is powered, well, to the ventilation of the cylinders.
The fact is that ventilation quite strongly affects the performance of the motor. To fix it, you should put a snokel, which is displayed on the roof of the car, in case of overcoming a ford. In frequent cases, a standard motor is injected, after which the power reaches 130 hp. With.
You also need to redo the transmission - install a low main pair. This moment will increase its capabilities somewhat. In addition, it is worth doing a body lift by putting large wheels. As a result, after tuning the UAZ with a V8 engine will look just amazing.
Once again about UAZ "Patriot"
It is worth noting that at the moment the Patriot line of engines has a ZMZ 409.10 atmospheric gasoline engine, the volume of which is 2.7 liters, and the power reaches 135 horsepower. This is at 4,600 rpm. At the same time, peak torque is estimated at 217 Newtons per meter at 3,900 rpm. The same engine is installed on the UAZ "Hunter". On it, it’s not bad at all, but for a heavy Patriot, traction at low speeds is definitely not enough.
The next option is diesel, the smallest thrust is somewhat better here. On bad roads and snow cover, the Patriot with this diesel engine somehow advances at the 1st reduced speed, and if you put large wheels and a bunch of different elements, it practically loses the ability to move off-road normally.
What needs to be done and where to stop
There is no comprehensive answer to this question. But it should be noted that in the Moscow region they nevertheless found an answer - they put a Chinese Cummins ISF 2.8 liter engine in the engine compartment of the Patriot. This is a turbocharged diesel engine with a good volume of 2.8 liters (though not very powerful - only 120.6 hp at 3,200 rpm), but it has an excellent torque peak of 295 Nm, which is available compared to the ZMZ diesel from 1 600-2,700 rpm.
A motor that copes well with the heavy Sobol, in which all-wheel drive asked to be installed on the UAZ.
Good advantage of Cummins ISF 2.8 l. It is also believed that it is quite common. In addition to the Sables, it is installed on gaziki and gazelles, and moreover, it can be without all-wheel drive. The inexpensive cost of a new engine, the availability of spare parts from domestic dealers and, of course, the ability to make repairs are also considered an advantage.
The following: diesel units from Japan, which are common for UAZs, are aging, motorists have already finished off a large number of the simplest and most indestructible engines from Japan, and customs control does not allow the import of cars and engines.
Current installation problems and solutions
The biggest problem with mounting the Cummins ISF 2.8L. on the UAZ "Patriot" - a very deep, in comparison with standard engines, sump of this engine. During large suspension travels, the Cummins sump hits the front axle beam. In order to avoid this, the engine was placed on high pillows. In general, the developers managed to install this motor with little or no difficulty.
Well, a few words in conclusion
Assembling the "correct" diesel unit is only part of this project. UAZ Patriot, as the developers conceived, was supposed to be a versatile off-road vehicle that is perfectly adapted to various operating conditions - from the highway to the snow cover, as well as swampy terrain. Without a good increase in the size of the wheels, this cannot be coped with, and therefore the suspension was modified to be able to fit thirty-five-inch tires.
To do this, to the "lift" of the body, the suspension was also "lifted", putting the Patriot rear axle from springs to shock absorbers, and also changing the rear drum brakes to disc brakes.
Well, in the process it turned out to be a very good all-terrain vehicle-SUV. As for the improvements, here the craftsmen did their best, and as a result, we see the UAZ Patriot, which is quite comfortable in many respects, which was finalized just fine.
What happened in the end, you can learn from this article and see the photos.
Some motorists put the engine from Nissan. If, of course, finances allow, you can put a more powerful engine on the UAZ Patriot. The power of this installation is about 150 horsepower - this fact is considered quite acceptable. This is a diesel engine, it is also installed for an electronically controlled installation. But with manual control, the power becomes less - only 135 hp. With.
After changing the standard engine from Nissan, the domestic Patriot receives the following features:
- The power is slightly increased. Now a Russian car is able to get out of any accident on its own, and pull out the same.
- Fuel consumption increases due to an increase in the power of the unit.
