Most drivers are accustomed to calculating fuel consumption for YaMZ per 100 km in liters, so the indicators in the tables may be incomprehensible to such people. The maximum theoretical diesel consumption per unit time is calculated using the formula: Q=N*q. In which N is an indicator of engine power, q is an indicator of specific fuel consumption, and Q is the maximum possible theoretical diesel consumption in grams per 1 hour of operation of the power unit at maximum power. This figure, in theory, is always ten grams higher than the actual consumption, since in practice the power unit does not constantly operate at its maximum.
Having received the fuel consumption in grams, you can convert it to liters. Depending on the temperature of the diesel engine, the weight of 1 liter of fuel is 830-860 grams.
It is important to remember that fuel consumption for trucks increases by 1.4 liters from the norm for every ton of cargo. The actual fuel consumption is also affected by the quality of the oil poured into the engine and low tire pressure.
Fuel consumption of MAZ truck tractors
One of the leading places among trucks in Russia, after KAMAZ, is occupied by the Belarusian manufacturer MAZ.
Such popularity of MAZs is largely explained not only by the fact that they are produced in the immediate
proximity to Russia, but also because they are perfectly adapted to our operating conditions. Just look at the participation of these trucks in Dakar.
Fuel consumption is of great importance when operating a truck.
Monitoring fuel consumption not only contributes to fuel economy, but also to early diagnosis of various possible problems that indirectly affect additional fuel consumption.
We invite you to familiarize yourself with the table of diesel fuel consumption standards for MAZ truck tractors.

But using these fuel consumption standards for trucks of this manufacturer, it should be taken into account that fuel consumption for every 1 ton of cargo increases by 1.4 liters.
In addition, fuel consumption is affected by the oil poured into the engine; synthetic oils reduce fuel consumption at low temperatures.
If your truck's fuel consumption has increased significantly and it differs greatly from the specified norms, and there are no objective reasons for this (weather conditions, workload), pay special attention to the technical condition of your vehicle.
It is advisable to carry out diagnostics to detect defects that may affect increased fuel consumption (low tire pressure, fuel system malfunction, imbalance, etc.).
For questions about diagnostics and repair of MAZ trucks, you can contact our specialists.
Fuel consumption is an important indicator Photo modifications
In order to exhaust all the potential built into the engine by the manufacturer, you must adhere to simple rules for maintaining the YaMZ-238. So, what happens while the car is not warmed up, the consumption fluctuates between 1.0 and 1.2 liters per hour; on the street it was approximately 10 degrees Celsius.

Maximum current, A - 50. Rated rectified voltage, V - 28. Starter - 25.3708-01, direct current, series excitation, with electromagnetic drive. Rated starter power, kW, at C20/182Ah - 8.2. When operating the YaMZ-238 engine, monitor the readings of instrumentation and signaling devices. The coolant temperature should be between 75-100C. It is not recommended to operate the engine under full load at a coolant temperature below 50C, since this worsens fuel combustion, products of incomplete combustion condense on the walls of the liners, the wear of liners and piston rings sharply increases, and engine efficiency decreases. During operation, a short-term increase in coolant temperature up to 105C is allowed. The oil pressure on a warm YaMZ-238 engine should be 400-700 kPa (4-7 kgf/cm2) at 2100 rpm and at least 100 kPa (1.0 kgf/cm2) at the minimum idle speed of the crankshaft. After long-term operation, it is allowed to operate the engine with an oil pressure in the lubrication system of not lower than 300 kPa (3.0 kgf/cm2) at the rated speed and not lower than 50 kPa (0.5 kgf/cm2) at the minimum crankshaft speed. On a car with a YaMZ-238 engine, the glow of the warning light when the engine is warmed up to normal temperature indicates contamination and increased resistance of the oil pre-filter element, the opening of the bypass valve and the supply of unfiltered oil to the lubrication system, which is unacceptable. The indicator light is allowed when starting the engine with cold oil and when warming up. Engine break-in occurs during the first 50 hours of operation. During this period, it is recommended to avoid full loads and high engine speeds. During the break-in period, the parts of the cylinder-piston group, gears, bearings and other parts are uniformly worn in in order to reduce their subsequent wear, and oil consumption is stabilized. Overloading during this period will negatively affect the break-in of parts and lead to a reduction in engine service life. When operating the YaMZ-238 engine during the break-in period, it is allowed to release a mixture of fuel and oil through the exhaust system, the formation of oil stains in places of oil seals that do not affect oil consumption, in the connections of fuel supply, lubrication and cooling systems, the release of individual drops of coolant or a mixture of it with lubrication through the drainage of the water pump, the formation of individual drops of oil and the release of condensate through the breather, without interfering with the normal operation of the engine.

MAZ-516
— three-axle large-tonnage truck. A distinctive feature of the machine was the “floating” third axle, which could be lowered and raised depending on the load. This made it possible to increase the vehicle's carrying capacity without exceeding the permissible loads on the road surface, and when driving empty with a raised axle, to increase maneuverability and reduce fuel consumption. MAZ-516 became the first Soviet truck with such a system.
The first batch of cars was produced in 1969. The design of the MAZ-516 is largely based on the MAZ-500, and after the plant switched to producing the modernized MAZ-500A, the three-axle vehicle was similarly improved, receiving the new index MAZ-516A. Its production began in 1973 and continued until 1981.
There was a modification of the MAZ-514, which was distinguished by the absence of a suspended 3rd axle (6x4 wheel arrangement); on its basis, in turn, the MAZ-515 truck tractor was created.

We adjust the ignition on YaMZ engines with turbocharging
Among diesel engines, the products of the Yaroslavl Motor Plant occupy a special place. Especially when it comes to episode 238. From its predecessor, the 236 series, the product inherited the same design features, to which two additional cylinders were added. The efficiency of the design is increasing.
There are no perfect products. When products start to break, they need to be fixed. Not every vehicle owner knows how to do this correctly.
Most often, the driver is concerned about the correct ignition setting. The check is performed independently. If the driver cannot independently check the injection angle and other ignition elements, contact a mechanic.
It is not recommended to consider the specific issue of setting the vehicle ignition in isolation from the more global problem of properly installing a heavy-duty engine.
Engine YaMZ 238 technical characteristics
One of the distinctive features of the development and development of the design of diesel engines of the YaMZ family is the focus on the simultaneous production of both models with a low level of boost and forced modifications with maximum mutual unification of their parts. If you look at the YaMZ-238 without touching on the technical parameters, then it differs slightly from the YaMZ-236 family; they simply added one cylinder to each row to the V-shaped six-cylinder unit, thereby obtaining an eight-cylinder unit.
Purpose of the YaMZ 238M2 engine
The YaMZ 238M2 diesel engine is the basic model developed by the Yaroslavl Automobile Plant. This eight-cylinder V-shaped four-stroke engine is designed for use in marine diesel-geared units, as well as for use in power plants.
This engine has excellent maintainability, and thanks to a competent design approach, repairs of this engine can be carried out in any conditions, and spare parts are widespread and easily available in Russia. All YaMZ engines are economical, cheap, reliable and of high quality. YaMZ 238M2 engines can operate in a wide temperature range of ambient air - from -50 to +50 degrees Celsius.
Features and operation Technical parameters
This figure, in theory, is always ten grams higher than the actual consumption, since in practice the power unit does not constantly operate at its maximum. Features of their configuration include the installation of a liquid-oil heat exchanger, a fan clutch and air ducts to the charge air cooler mounted directly on the engine.

Durability, reliability, unpretentiousness, acceptable and good power range; impressive design and therefore technological diversity, in an effort to adapt to each specific model of car or tractor - all this is about the classic Yaroslavl eight-cylinder engines.
Fuel consumption of YaMZ-236 © Modifications of YaMZ 238 and their differences
Plus, the actual indicator of the car’s appetite is closely related to such parameters as tire pressure, quality of diesel fuel and motor oil. When these parts fail, the camshaft stops rotating, causing the intake and exhaust valves to not open or close.
| Crankshaft failure | Operating the engine with engine oil that does not meet the required standards. Decreased lubricant consistency due to the ingress of diesel fuel or coolant into it. A drop in oil pressure due to dirty filters, excessive wear of the crankshaft liners, as a result of oil pump failure or violation of maintenance regulations. |
| Destruction of intake and exhaust valves and their opening and closing mechanisms. | Incorrect valve clearance adjustment, camshaft wear, deformation of push rods. |
| Failure of the injection turbine (on engines equipped with injection devices). | Depressurization of the injection path. Deterioration of lubricant supply to turbine elements. |
How to reduce fuel consumption
Even the most economical vehicle will consume a lot of fuel if its owner adheres to an aggressive driving style. To avoid facing additional costs, drivers should follow a few simple rules. In particular, do not press the gas pedal when it is not necessary. Fuel burns most efficiently only during smooth acceleration.
How to reduce fuel consumption
Want to know how to reduce fuel consumption when driving in urban areas? To do this you need:
- stop accelerating the car in advance if an obstacle arises ahead;
- always choose the optimal driving mode that corresponds to the speed and intensity of traffic flow;
- do not forget to use the inertia of movement: when approaching an intersection where the light is red, do not press the brake, but release the gas and brake with the engine.
When answering the question of how to reduce fuel consumption, one cannot fail to mention the choice of route. Shortcuts are not always the most profitable. Experience shows that it is much better to drive slowly than to constantly stand in traffic jams. Don't forget about the quality of the road surface. If the road is riddled with potholes, you will have to brake before each of them, which will significantly increase fuel consumption.
Car operation
Do you want to reduce fuel consumption? Then reduce the load on the generator and, accordingly, on the engine. To do this, you will have to give up additional headlights, heated seats, and the use of a car radio. The air conditioner consumes the most fuel - about 0.6-0.8 liters per 100 kilometers. Therefore, sometimes it makes sense to limit yourself to ordinary ventilation. However, do not forget that open windows when driving at high speed increase the aerodynamic drag of the car.
Also pay attention to the presence of excess cargo in the trunk. If the permissible load on a car is exceeded, excessive fuel consumption can exceed 20%. Installing a roof rack on the car also increases fuel consumption by 10-20%. In addition, if the car's fuel consumption has increased, it is quite possible that one of its components has failed.
Engine idle speed
Fuel is burned in large quantities when the engine idles for a long time. Therefore, if you find yourself in a traffic jam or make a long stop, you should always turn off the engine.
Using the on-board computer
The on-board computer can help you save fuel. If this device is not included in the basic configuration of the car, it can be purchased separately as additional equipment.
Reduced pressure • Technical parameters
| How to add fuel to YaMZ 238 - Special equipment Despite the almost perfect design of the engine, its service life and a large margin of safety of the main working components and assemblies, the diesel engine is characterized by some malfunctions. Modifications of power units in this line are designed for stable operation in a wide range of climatic zones, temperature conditions and other difficult conditions. |
- Cooling system – liquid forced type;
- The liquid used for the cooling jacket is antifreeze, antifreeze or water;
- The maximum power of the power plant depends on the modification and ranges from 182 to 500 horsepower.
Maintenance of the YaMZ 238 lubrication system • After 2-3 minutes, the system warmed up, consumption dropped to 0.7-0.8 liters per hour.
Types of motors of the YaMZ-238 family and their features
4. fuel quality. High-octane gasoline A-95 releases more energy than A-92, and, accordingly, to maintain the same speed, less fuel with a higher octane number will be required. Here you just need to remember that not all engines are capable of running on high-octane gasoline without compromising their technical condition. It is better to refuel your car at proven gas stations, because low-quality gasoline leads not only to increased fuel consumption, but also to increased engine wear.

Most drivers are accustomed to calculating fuel consumption for YaMZ per 100 km in liters, so the indicators in the tables may be incomprehensible to such people. Since 2000, the optional body of this model began to be equipped with heating, so it became possible to transport special liquid mixtures and concrete solutions over impressive distances in winter.
Vehicle description – Technical parameters
For example, China orders engines of this series for its heavy-duty trucks, since only BELAZ and Caterpillar can compete with YaMZ, but they are much more expensive than their domestic counterpart. At that time, it was a unique engine of its kind, which was produced for half a century, and established itself as one of the best power units in the whole world.
