UAZ car (diesel), the operation and repair of which are simple and affordable, is available in various versions. Consider the features of the versions on the example of two popular modifications: 469 and Patriot, as well as a brief overview of other variations of the car from the Ulyanovsk Automobile Plant.
Features of installing a diesel unit on the UAZ-469
When installing the diesel version of the engine on a traditional gasoline version of the 469 series, they most often use suitable analogs from foreign cars (Nissan, Toyota SUVs). Among the advantages of the power unit:
- better disposition for cargo transportation;
- lower specific consumption compared to gasoline;
- environmental friendliness, due to the lower content of lead in high-quality diesel fuel;
- high rate of reliability and maintainability.
Among the main disadvantages, poor diesel performance at low temperatures is noted, especially in the Far North regions. Repair of such an engine also does not please many consumers, since it costs more than a gasoline analogue.
During the operation, tuning and repair of an UAZ (diesel), black or blue exhaust emissions are often observed in the atmosphere. This can be considered both a minus and a plus, depending on the aesthetic preferences of the owner, however, it does not pose a threat to the car. In any case, the choice is yours!
What diesel can be put on the UAZ "Loaf"?
Before changing a gasoline engine to a diesel analogue, in the case of this model, you must carefully weigh the pros and cons. If the availability of appropriate equipment and the possibility of proper maintenance allows, go for it and experiment!
The second subtlety that needs to be taken into account in this matter is who will be responsible for the installation, tuning, operation and repair of the UAZ diesel? It is advisable to make sure that there is a company near you that guarantees high-quality transformation of engines. You can independently do this procedure, but it is rather difficult to perform. Special devices will be required to remove and install mechanisms that are difficult to deploy without an assistant. The best option is to contact the specialized service station, where experts will correctly and reliably mount all the elements in a short time.
Recommendations
First of all, it is necessary to determine the configuration of the diesel UAZ model. It takes into account the dimensions, technical parameters and cost of the unit. Most foreign quality installations have a high price, from 40 thousand rubles and above. But this fact does not stop the determined owners of domestic SUVs.
Many craftsmen opt for a simple two-liter engine with atmospheric cooling type "CT" ("Toyota"). This modification causes a rather low power indicator (88 horsepower), as well as a low speed parameter. The version of the diesel TD-27-ETI will become more relevant. In this version, 130 "horses" can cope with the real tasks of transporting goods and passengers.
Also popular diesel engines for the "Loaf" are units from the Mercedes (OM-616). They have proven themselves excellently, do not require special maintenance, are reliable and practical. The only negative is the problems with the dynamics.
UAZ "Patriot" diesel (ZMZ)
Modifications of this car on a gasoline or diesel engine do not have any special differences. The power of the second option is lower (128 hp), however, the disadvantage is leveled by improving the torque (270 vs 217 Nm). The difference is especially noticeable on the road.
It is worth noting that the gasoline engine “eats” about 12 liters per 100 kilometers, and the fuel consumption on an UAZ diesel is 2-3 liters less. Given the characteristics of driving and the cost of fuel. The speed threshold of the car in diesel fuel is 135 km / h. This is 15 kilometers less than the gasoline counterpart. Due to the design differences between the two different types of engines, the engine compartment for each variation is made differently.
Operation Nuances
The use of diesel engines requires compliance with certain rules. This is due to the fact that this type of fuel is characterized by a high sensitivity to thermal parameters. Experts recommend following these tips:
- Do not start the engine at sub-zero temperatures immediately. It is advisable to put the ignition key in the first position, and then wait 2-3 minutes. After that, the engine can be started, since the fuel filter warms up previously to the desired condition.
- The vehicle must be run-in. During the first 2.5 thousand kilometers, use the car in a gentle mode, with a minimum load.
- Pour diesel fuel that meets Euro-3 standard and above into the fuel tank.
It so happened that for an UAZ diesel, tuning, operation and repair are more expensive than gasoline counterparts. However, the savings are manifested in increasing the carrying capacity and operation of the car. Nevertheless, at critical driving parameters, the service life of the power unit is significantly reduced due to a sharp overheating.
Service
Any power unit needs timely maintenance. This procedure involves changing the oil every eight thousand kilometers. This approach makes it possible to ensure the extension of the working life of internal rubbing parts. To optimally adjust the procedure, it is recommended to use the same brand of grease.
Another caveat is the timely replacement of the timing belt. It must be carried out after every 60 thousand kilometers. Otherwise, the risks of unexpected breakage of the element increase, which is fraught with a breakdown of the cylinder heads and associated parts. It is also necessary to change the fuel filter element after 8 thousand operation of the car. According to reviews, UAZ Patriot with a diesel engine requires flushing the fuel tanks every two years, as sediment and associated weeds accumulate in the tanks.
Motor tuning
It is possible to improve the characteristics, despite the type of engine installed in the UAZ, as follows:
- Carrying out chip tuning, expressed in the modernization of the powertrain control program. The procedure makes it possible to increase the total power of the “engine”, start in idle mode with a cold start, engine performance.
- Install an additional turbine that increases the performance of the power unit. In this direction, additional software development is practiced.
- Further tuning UAZ "Patriot" (reviews confirm this), consists in conducting events with the rest of the car. This category includes increasing noise, thermal insulation and interior refinement.
Constructional moments
The cylinder block and the motor head of the machine are made of aluminum alloy by special surfacing. This made it possible to significantly reduce the weight of the power plant. The UAZ "Hunter" engine (diesel ZMZ) is placed superficially, with a separate position of the intake and exhaust valves.
The gas distribution mechanism operates by means of an intermediate shaft and associated elements. The mechanism is stabilized by means of hydraulic tensioners and special soothing mechanisms.
Attachments are driven by activating V-belts driven by a gear train. Thermal clearance is controlled by hydraulic compensators. Each combustion chamber has four valves for inlet and outlet. The piston group of the device works according to the 1/3/4/2 scheme.
Typical malfunctions
The table below shows the main problems that arise during the operation, tuning and repair of an UAZ diesel.
Causes | Solution options |
Missing or poor fuel supply to the pump unit | Cleaning the mesh filter element |
Difficulty starting the engine at sub-zero temperatures | Check and replace, if necessary, spark plugs or glow plugs |
Motor weakly develops the indicated power indicators | Fuel should be adjusted |
Similar malfunctions in terms of power reduction | Sealing failure, malfunction of the timing or turbine compressor |
Powertrain smoke | Increased oil content, clogged filter, refrigerant leakage into the working cylinders |
Increased oil consumption | Long operation at low speeds, breakdown of the coolant status indicator, malfunction of the air filter, thermostat |
Consumer feedback
According to reviews about the UAZ "Patriot", on the diesel version, the correct installation of the unit plays an important role. In addition, it is necessary to correctly match the engine with the gearbox. Suppose, on the “machine” it will be enough to reflash the on-board computer, which will make it possible to make the aggregation of nodes as logical as possible.
The mechanics in this regard are much finickier. It is necessary to put such a box, which is ideal for a specifically installed diesel engine (ZMZ UAZ "Hunter" or analogues). In any case, it is better to entrust the work to specialists if there are no relevant skills and absolute certainty.
