Fuel consumption per 100 km on KamAZ depends on the type of diesel engine installed, transmission layout and superstructure configuration. The plant offers models with rear trolley drive.
The production program includes 6x6 versions with improved cross-country ability at the expense of efficiency.
... about the model parameters
For a long time, naturally aspirated engines with mechanical high-pressure pumps were installed on cars, but since the early 2000s. The manufacturer began to use engines with electronic control and reduced fuel costs on trucks.
Fuel consumption depends on the engine type.
Technical characteristics of KamAZ vehicles
KamAZ trucks are equipped with a frame chassis with a cab mounted above the engine. The vehicles are equipped with Russian power units from KamAZ and YaMZ plants, as well as imported engines (for example, Cummins or Daimler, corresponding to Euro-5).
The product line includes chassis with 2 or 3 axles. The gearbox can be equipped with a divider that doubles the number of stages and expands the transmission range.
The axles are mounted on leaf springs. Pneumatic cylinders with nonlinear rigidity are used on parts of the tractors.
For military customers and installation of special equipment, 3-axle vehicles with an all-wheel drive system are produced. The transmission includes a transfer gearbox with a reduction stage, which improves maneuverability on soft ground or wetlands.
The vehicles are equipped with a centralized tire pressure regulation system and a locking center differential. Additional components and shafts included in the transmission increase fuel costs by 25-30% compared to a civilian chassis.
Technical parameters of the KamAZ-5350-66 truck:
- transmission diagram - 6x6;
- engine - Cummins ISBe6.7 E5 285;
- power - 277 hp. With.;
- curb weight - 9,600 kg;

The plant offers ready-made dump trucks with a hydraulic rear unloading system (a 3-way tipping system is available upon request).
For example, the popular KamAZ-6520 vehicle, driven by a rear 2-axle balancing bogie, has a load capacity of up to 20 tons with a dead weight of 12.95 tons. The vehicle uses supercharged diesel engines, the cabin is equipped with a high roof (a sleeping compartment can be installed upon request).
Excessive fuel consumption. How to make a motor more economical
- Excessive fuel consumption is associated with sudden starts and braking. At this point, the engine is forced to operate at high speeds with a low gear engaged, and this causes excessive consumption. In this case, it is necessary to avoid frequent braking and intense acceleration, which is especially important in dense traffic. In such conditions, you must maintain a constant speed and coast - for example, when approaching a traffic light. This will reduce consumption by 1-2 liters.
- If possible, you should refuel only at proven gas stations, and all motorists are aware of this fact. However, prudent and economical truckers, in pursuit of profit, prefer to fill with fuel of dubious quality, especially if we are talking about an old KamAZ engine. For this reason, the engine not only consumes more fuel, but is also prone to various breakdowns. The consequences of this are unpredictable - long downtime, force majeure, etc.
- To maintain a constant speed of movement of the wheels, the engine makes the necessary efforts for this. We are talking about the amount of tire rolling resistance, which depends on the tire pressure. In other words, lower tire pressure increases rolling resistance, which increases the load on the engine and requires more fuel to produce the required power. Therefore, it is important to promptly check the pressure in the tires, which must be inflated to certain values, exceeding which can cause rapid tire wear and impair handling. It is believed that properly inflated tires improve engine efficiency by 0.5 liters.
- Correct route planning is a guarantee of reliable and economical operation of the engine, which will operate without overload. The route does not have to be too short. Here it is important to take into account traffic congestion, traffic jams, etc. Thanks to various Internet navigation services, you can choose the ideal route that will reduce consumption by 5-10%.
- Fuel consumption is distributed as follows: 30% – movement 35% – tire rolling resistance 35% – aerodynamics The indicated values naturally increase as the speed increases. So, at a speed of 88 km/h, 33% of the fuel will be spent on aerodynamics, 33% on tire rolling resistance and 34% on the rest. At a speed of 120 km/h these figures increase to 46%, 24% and 30% respectively.
- Fuel consumption can be reduced by competent and timely gear shifting, and you also need to operate the clutch correctly. The most economical mode is to travel in fifth or sixth gear at 2500 rpm. But if you increase the speed to 3000, this will lead to a threefold increase in consumption. Optimal speed depends on the specific engine model, but in most cases it should not exceed 1500 rpm.
Indicators taken into account when calculating fuel consumption of Kamaz
When calculating consumption rates for Kamaz, like other trucks, the following are taken into account:
- base coefficient , which allows you to determine the fuel costs for a vehicle in your fleet;
- correction index , taking into account the type of road and altitude above sea level (as you climb mountains, fuel costs increase);
- coefficient of climatic operating conditions (for winter allowances additional validity periods are established);
- indicator of taking into account the trajectory of the road (the number and radius of turns, on which the intensity of acceleration depends);
- technical condition coefficient (it is used for new equipment or trucks that have undergone major repairs);
- indicator of car wear and tear (it depends on mileage and age).
Indicators can both increase standard costs and reduce the amount of fuel written off.
... about calculating fuel consumption
The owner of the equipment has the right to introduce additional coefficients to take into account fuel consumption for maneuvering in garages or on the territory of a motor vehicle fleet.
The indicator compensates for the costs of fuels and lubricants arising as a result of routine inspections, adjustment of units or running-in of components after repairs.
Adjusting the Kamaz clutch video
For the new KAMAZ vehicles at Com-trans 2010, not only the appearance, but also many components have changed, which has made it possible to reduce KAMAZ fuel consumption by another 5-10, depending on the season of operation. Legal entities or individual entrepreneurs can clarify the initial and final dates of the application period and the values of winter surcharges, within the recommended limits for a given region, in case of significant deviations in temperature decreases or increases from the average daily or monthly long-term average statistical values - in agreement with the regional local services of Roshydrometcenter and the Ministry of Transport Russia.
What factors influence fuel consumption per 100 km
The efficiency of freight transport is influenced by the following factors:
- technical condition of the engine, gearbox and gearboxes in axles;
- serviceability of brake drives;
- weight of transported cargo;
- driver experience and driving style;
- profile of the road along which the route is laid;
- number of stops made during cargo delivery;
- type of superstructure installed on the chassis (drag resistance increases with increasing height);
- power of the power unit (models with a supercharger have reduced fuel consumption).

Average fuel consumption rates depending on the Kamaz model
Standard fuel consumption depends on the number of axles, the type of power unit and the design features of the superstructure. Average values are given in the tables of the Ministry of Transport, which are the basis for determining fuel costs when operating equipment.
... about fuel consumption
The maximum efficiency is achieved by KamAZ-4308 flatbed light-duty trucks, which pack 19.7 liters.
The largest volume of fuel is burned by model 6522 tractors, designed for transporting trawls with heavy tracked vehicles (the standard consumption is set at 52.1 liters per 100 km).

Chassis
The KamAZ plant ships ready-made chassis designed for installation of various equipment to customers. Cars do not have individual model designations, so fuel consumption is not indicated in regulatory documents.
For example, the manufacturer transfers the KamAZ-6560 chassis to the Ural Fire Equipment Plant, which assembles the vehicle under the designation 5662SNAA 13/60.
The installation is indicated in the Ministry of Transport standards under the final index and has a standard fuel consumption of 44.5 liters per 100 kilometers.
What they're talking about on the forums: reviews from KamAZ-53605 owners and drivers
Thanks to the design perfected over the years of production, the KamAZ 15-ton truck is distinguished by significant reliability, excellent maintainability and consumer characteristics that are optimal for operation in Russia and the CIS. For dump trucks and road trains with dump bodies, a fuel consumption rate Ng is additionally established for each trip with a load when maneuvering at loading and unloading areas.
How to correctly calculate Kamaz fuel consumption per 100 km
To calculate diesel fuel consumption standards, formulas and coefficients approved by the Ministry of Transport of the Russian Federation are used.
Government agencies periodically revise standards, introducing new models of equipment into the tables.
For example, for KamAZ-4308 with a Cummins 4ISBe185 power plant and a 6-speed transmission, fuel consumption is set at 19.7 liters per 100 km. Model KamAZ-65117 with a KamAZ-740.30 engine with a power of 260 hp. With. and a 5-speed gearbox with a divider consumes 25.1 liters of fuel.
To calculate the volume of fuel and lubricants consumed during a work shift or other time interval, use an equation of the form Q=0.01*H*S(1+0.01*D)+J*Z, where:
- Q—calculated value;
- H is the standard flow rate taken from the tables;
- S — mileage per shift or other time interval (specified using the speedometer or GPS device);
- D is an adjustment factor taking into account operating conditions;
- J is an additional consumption rate that takes into account the decrease in efficiency when traveling with a load;
- Z is the number of work trips made during the analyzed time interval.
If an organization operates equipment with stationary equipment (for example, pumping or drilling stations), then when calculating fuel consumption, the operating time of the installation and the fuel consumption standard for driving the tool are taken into account (either from the main diesel engine or from an additional unit installed on the superstructure).
... about fuel consumption in difficult conditions
It should be taken into account that performing work in difficult conditions leads to an increase in diesel fuel consumption by 50-70%.
Some equipment owners are faced with the problem of the influence of additional factors on trucks that are not regulated by the Ministry of Transport of the Russian Federation (the difference between the calculated and the figures obtained during operation is up to two times). In this case, it is recommended to develop your own standards using satellite tracking systems for trucks.
Control allows you to reduce the risk of fuel theft or drivers making idle trips or traveling on unplanned routes.

The procedure for accounting and writing off fuel and lubricants on waybills in 2022
Knowing the appetite of your vehicle allows you to calculate the required amount of fuel for a certain distance. As a result, you can intelligently approach your travel costs. And if with passenger cars everything is a little easier - there is not particularly great gluttony here, then freight transport is already distinguished by high needs. What kind of appetite does a car like KamAZ have? The fuel consumption of this vehicle cannot be compared with the appetite of any other vehicle (aircraft and ships do not count).
Vehicle modifications • Parameters and load capacity
It is important to remember from the table presented above that it becomes clear that the indicators differ greatly from the power of the KamAZ engine, from operating conditions and from the time of year. Legal entities or individual entrepreneurs can clarify the initial and final dates of the application period and the values of winter surcharges, within the recommended limits for a given region, in case of significant deviations in temperature decreases or increases from the average daily or monthly long-term average statistical values - in agreement with the regional local services of Roshydrometcenter and the Ministry of Transport Russia.
