Calculation of fuel consumption of the MTZ-80, MTZ-82 tractor

The technical characteristics of the MTZ 82 tractor allow you to carry out a wide range of work and technological operations in agriculture, construction, various industries and the public sector. Aggregating the tractor in combination with various mechanisms, trailed and mounted equipment makes it possible to use this equipment as efficiently as possible.

Calculation of fuel consumption

When calculating and calculating the cost of work performed, an important component is the amount of fuel consumed by the tractor. The fuel consumption of the MTZ 82 indicated in the specifications by the manufacturer, taking into account the D-240 engine brand, is 238 g/kWh, which is completely inconvenient for an understandable economic calculation of the cost of the work performed by the equipment and accounting for fuel consumption. The most relevant unit of measurement is “liter per hour” of tractor operation.

Factors affecting consumption

The characteristics specified by the equipment manufacturer are nominal average values. In practice, the deviation from the nominal value of fuel consumption is influenced by a number of factors and conditions:

1 Technical condition of the engine, as well as the condition and adjustments of all systems

• Condition of the engine piston group
• Adjusting the engine timing mechanism
• Adjustment and technical condition of fuel equipment
• Air supply condition and operation.
• Tractor cooling operation.

2 External factors

• Driver qualification
• Type of work performed
• Weather
• Humidity and physical condition of soils.

3 Fuel quality

The composition of the fuel must meet quality standards in accordance with approved certificates, without foreign physical contaminants and chemical impurities.

Calculation formula

P = M * T

where, P is fuel consumption kg/hour, M is the rated engine power kW, T is the estimated fuel consumption per 1 kW per hour.

And so: Consumption of MTZ 80 with an engine model D 240, where according to the technical specifications. characteristics, fuel consumption is 0.238 kg/kW*hour and rated engine power is 59.25 kW. at 2200 crankshaft revolutions. (initial engine indicators are taken from the technical documentation of the manufacturer)

Р=59.25 kW*0.238 kg\kW.h=14.1 kg\h

To convert from kilograms to liters we use the coefficient:

• For winter design. fuel 1kg-1.19 liters
• For summer design. fuel 1kg -1.16 liters

“The nominal consumption at an engine speed of 2200 rpm and maximum power output of 59.25 kW is 16.35 liters per hour of summer and 16.78 winter grades of diesel fuel.”

Tractor load factor

The actual used engine power depends on the work performed by the tractor and in practice, the average value does not exceed 60%. Accordingly, when calculating consumption, it is not the maximum engine power that is taken into account, but the actual power used during the work performed. For an objective, actual calculation of consumption, the tractor load factor is used:

• Full load -1
• Partial load -0.8
• Average load - 0.6
• Light load - 0.4

Calculation of consumption taking into account load factor.

Thus, MTZ fuel consumption taking into account the power utilization factor of a tractor with a D 240 engine, where P = 16.35 l/hour

• at full load 16.35 l/hour
• partial load 16.35*0.8= 13.08 l/hour
• average load 16.35*0.6= 9.81 l/hour
• small load 16.35*0.4=6.54 l/hour

Since the operation of equipment is carried out in different work processes and a large range of factors influences the use of engine power, the selection of the coefficient is determined experimentally. You need to focus on the actual engine speed when performing a specific work operation. If similar experimental measures are carried out on all processes in which a tractor is used, the objectivity and accuracy of accounting for fuel consumption will be as close as possible to the actual one.

Table of fuel consumption MTZ 80, MTZ 82 per hour by engine brand:

To account for fuel consumption in agriculture, since the times of the USSR, approved consumption regulations have been in force for all types of technological operations and agricultural work by brand of tractors and units used.

It should be noted that the first reason for increased consumption is a malfunction or incorrect adjustment of the diesel fuel mechanisms. Diagnostics and adjustment of fuel equipment (fuel injection pump, injectors - sprayers) is carried out on special stands equipped with appropriate sensors.

Calculation using the formula - constant and variable quantities

According to the manufacturer's regulatory documentation, the specific fuel consumption at the rated power of the power plant is 220 gkWh.
(162 hl.s.h.). However, it should be noted here that this indicator is influenced by a very large number of factors - engine speed, gears used, load, engagement of the front axle (if equipped) - this is not a complete list of them. On average, about 9.5-13 liters are consumed per hour. The formula for calculations is as follows

P – consumption per hour, kg/hour;

0.7 – coefficient for converting the power of the propulsion system into hp. from kW;

R—specific fuel consumption, gkWh;

N is the power of the propulsion system, hp.

Example. Hourly fuel consumption for MTZ tractors is calculated as follows

P=0.722075=11550 ghour, or 11.5 kghour.

Consumption indicators “liters per hour” are calculated based on data from the hour meter. These indicators are also not constant and primarily depend on the load placed on the tractor (full load with a load capacity coefficient of 1, partial - 0.8, half - 0.6, partial - up to 0.5), as well as on the type of road surface ( Group 1 - hard surface in good condition, Group 2 - gravel or crushed stone surface of average quality, Group 3 - broken, high-rut surface of low quality).

Calculation of MTZ 80 fuel consumption rate per 100 km

The consumption is determined based on the speed technical characteristics of the tractor, specific consumption l/m.h and load factor.

1 we determine the time it takes the tractor to travel 100 km.

Where B is the travel time of 100 km, C is the speed per hour (for example, the speed the IX gear of the MTZ-80, MTZ-82 with the D-240 Engine is indicated).

V=100/C

B=100/34.31= 2.915 hours.

2 determine the amount of fuel per 100 km.

P per 100 km = B*P*0.6 where, P is the specific engine consumption D-240 l/m.h., B is the travel time of 100 km in IX gear, 0.6 load factor.

R per 100 km = 2.915 * 16.35 * 0.6 = 28.59 l / 100 km

Table of fuel consumption per 100 km, taking into account the choice of gear and load factor.

Km/hour

The need for this calculation arises only when using the tractor for transport work on paved roads, which in itself is a rare exception in the use of this type of equipment. The cost of transporting a ton per kilometer using such transport will be disproportionately high compared to road freight transport.

If the tractor is used for transport work within the city, the unambiguous objective unit for accounting for consumption will still be a liter per engine hour. It is enough to take into account: operating time, power of the diesel model, specific consumption for this engine and determine the load factor, which in practice will not be higher than 0.6.

Features of individual calculation

To determine the average, the car must travel 100 km, after which the degree of consumption is established. In this case, the machine and all its components should work normally. It is worth noting that the fuel consumption of tractors is measured per hour in liters.

To calculate using the formula, the following transport values ​​are used:

R—specific fuel consumption;

N—power in horsepower;

P – fuel calculation for 1 hour.

In addition, a conversion factor from kW is applied, which is 0.7. The final formula is P=0.7*R*N. When calculating, you need to remember that different equipment equipment gives different indicators, and at the same time, under working conditions, the load is not always full, which can greatly affect the result.

The fuel consumption of tractors per 100 km is determined under individual operating conditions. This means that even for the same model with the same technical characteristics, working in a different landscape type, additional adjustments will have to be made.

MTZ fuel consumption standards for 1 engine hour or 100 km

The fuel consumption of the MTZ 82 Tractor can be viewed in the waybill, where the fuel consumption rate and actual fuel consumption are indicated. With the same document, future consumption of the fuel and lubricant mixture is planned. In this way, the owner can calculate consumption and calculate future costs.

Consumption per 1 engine hour: During transportation, 8.5-13 l/h is usually spent. When plowing and other agricultural work, a consumption of 10-19 l/h is possible.

Consumption per 100 km: Depending on the load and the drives turned on, from 16 to 40 liters of fuel.

The MTZ-80 tractor is a reliable and functional vehicle, the use of which allows you to solve an unusually wide range of not only agricultural, but also other tasks, achieving the highest possible productivity and profitability at minimal cost. In many ways, this is facilitated by the careful fuel consumption of the MTZ-80, and this is exactly what we will talk about today.

Fuel consumption - what you should pay priority attention to

Actual indicators for the MTZ 80 tractor are calculated based on observations of the vehicle.
The fact is that, based on operating conditions and climatic characteristics, they can have very significant differences, and that is why when making calculations they always take into account linear or, as they are also called, basic standards, using an overestimated correction factor for them. The fuel consumption rate is calculated based on the fact that the vehicle is in good technical condition. If everything is in order, the mileage is set at 100 km and the amount of fuel consumed during this period of travel is recorded. It is measured in liters, taking as a basis a machine hour, or a certain unit of labor with cyclic repetition.

To carry out the most accurate calculations, a special formula is used, which, however, is equally relevant not only for MTZ 80 tractors, but also for all other types of equipment, both agricultural and other.

Fuel and lubricants write-off act

roads with fairly deep ruts, partially frozen arable land or a surface of normal humidity, roads that have not completely thawed during the thaw, spring off-road conditions and completely broken tracks. 25 of the Tax Code of the Russian Federation does not provide for rationing the consumption of fuel and lubricants, moreover, it does not contain any references to standards, however, the amounts of expenses must be taken into account when calculating profit tax in full, taking into account the provisions of Art.
