Fuel consumption of Mtz 1221 during Field Work © Chassis • DRIVER'S TALK

The tractor is also too voracious for its price category - fuel consumption is around 20 liters.

The car was in excellent condition, practically new.

But no, Belarusians need savings, and raising prices is our way, as they say. There is sun protection, sound insulation, and an emergency exit on the roof.

I have a MTZ tractor from the year it was produced, a powerful and productive machine, very voracious and does not require serious expenses.

But the tractor is worth the money spent.

The tractor is especially voracious if you work with a cultivator or a five-furrow plow. The brake system has a dry three-disc type. Mounting device.

I mean increased fuel consumption - my car at peak load consumes around 25 liters per km. All main control levers are located on the right, including control of the machine’s hydraulics, attachments, manual fuel supply mode, PTO, FDA functionalities, etc. Gear diagram MTZ 1221-1523-2022 How to properly operate the gearbox

Fuel consumption of Mtz 1221 Tractor per Hectare

Proper calculation of diesel fuel consumption on tractors allows companies that own special equipment to save on fuels and lubricants and maintaining their fleet.

The specific fuel consumption of tractors is indicated in the instructions. To perform calculations, different manufacturers use their own formulas. It must be understood that these calculations are carried out taking into account the fact that the tractor is operated in “ideal” conditions, that is, on a flat road, without the influence of atmospheric phenomena, etc. For each tractor model, fuel consumption per hour is determined individually; it depends on the operating conditions of the vehicle.

Reasons for increasing/decreasing fuel consumption

More or less consumption, compared to the norm, depends on various reasons. The main one: the technical condition of the engine. Features of operation, average speed, load capacity, precipitation, and road surface are also taken into account. The latter is divided into 3 types:

hard (soil, compacted snow);
gravel, sand (medium hard soil);
wet (arable land, snow-covered virgin soil, off-road).

Why does the MTZ 1221 engine get hot?

Taking into account the in-line six-cylinder design of the piston part of the diesel engine and the remote location of the two outer cylinders from the heat exchange point of the coolant, overheating occurs due to the fact that the liquid passing through the jacket of the block reaches the fifth and sixth cylinders sufficiently heated. Thus, this diesel engine is very sensitive to disturbances in the operation of the cooling system.

Owners of early versions of tractors, where the heat transfer capacity of the diesel radiator was insufficient, often complained about overheating of the MTZ 1221 diesel engine. Typically, overheating occurred when work was performed with the tractor delivering maximum power—plowing and other soil cultivation operations. Experienced tractor drivers mitigated this disadvantage of the machine by reducing the operating speed of the unit or reducing the depth and width of processing.

And also many have successfully solved this problem by installing additional electric radiator blower using any automobile electric fan powered from the tractor’s on-board power supply. Subsequently, the manufacturer solved this drawback by equipping the engine with a more powerful radiator.

Direct causes of overheating

If there is a malfunction in the operation of the MTZ 1221 diesel engine in terms of its cooling, first of all you need to pay attention to the direct factors that determine the operation of the liquid cooling system of any engine.

Direct factors affecting the efficiency of the cooling system are:

Cooling system tightness
Presence of coolant level
Serviceability of the system thermostat (thermostat)
Correct pump drive belt tension
Serviceability of the pump drive belt tension spring
Inadmissibility of oiling the drive belt causing slippage
Absence of heat-insulating scale in the water jacket of the diesel unit
Radiator contamination, reducing heat transfer

Indirect causes of overheating

In addition, the reasons may be disturbances in the operation of other diesel systems:

Incorrect adjustment of the injection advance angle and quality of fuel atomization with a simultaneous drop in diesel power.
Breach of the diesel cylinder head gasket with gases escaping into the diesel jacket.
The most negative factor influencing overheating and, in general, a sharp decrease in the life of a diesel engine or its complete failure, is an unacceptably low level of lubrication, which provokes high friction in the engine mechanism.

The procedure for writing off diesel fuel for a diesel generator

In its absence, you can get out of this situation by approving the fuel consumption rate for a working day or setting the kilometer to approximately the distance traveled with further calculations according to the standards. But before leaving the garage, it is necessary to measure the volume of fuel in the tank.

If such a system is organized and functions properly, then the fuel is written off in the amount actually consumed. The resolution of the Federal Antimonopoly Service of the West Siberian District dated 04/05/2012 in case No. A27-8757/2011 (supported by the decision of the Supreme Arbitration Court of the Russian Federation dated 07/09/2012 No. VAS-8327/12) explained: Ch. 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.

The technological necessity of their implementation can be confirmed by the production and technical department.

Individual consumption rates, taking into account all factors, are established by the commission using a test method (a certain amount of fuel is poured into an empty fuel tank and it is determined how many hours it takes to completely use it).

Subsequently, the actual consumption is compared with the calculated one.

Identified discrepancies (savings or overruns) are analyzed by the internal control service.

Important The enterprise should draw up a list of vehicles on its balance sheet in order to correctly justify its expenditure on fuel and lubricants.

/ / April 11, 2022 4425 0 Share We recommend the collection Write-off of fuel and lubricants based on waybills - you will find an example of the calculation further in our material.

Properly established write-off accounting will allow you to more carefully control the consumption of fuel and lubricants and avoid their losses.

Information on fuel consumption standards (0.5 liters of A-92 gasoline per hour) was found on a website on the Internet. Can this information be used as a guide when determining fuel write-off standards? The company plans to formalize fuel write-off standards by order.

The company asks for clarification on how to keep records of the operation of the generating set, and what document should be used to write off the consumption of fuel and lubricants during the operation of this installation? The company purchased a generator set to generate electricity for its own needs, the fuel for which is gasoline.

In these modes, fuel is consumed in the form of technological losses, which are inevitable in any production process.

Fuel and lubricants is a generally accepted abbreviated name for a group of fuels and lubricants. These include:

oils and lubricants (motor oils, transmission oils, various lubricants, etc.).
special fluids for vehicles (brake, cooling);
various types of fuel (diesel, gasoline, gas);

Fuel and lubricants can be used by both specialized transport enterprises and ordinary companies that have vehicles used for various needs.

The universal Belarus 1221, which first rolled off the assembly line in 1979 and today is successfully used in all types of agricultural work of any complexity, in construction, logging, transport and municipal services.

Chassis and transmission of the MTZ-1221 tractor

The tractor transmission has a number of significant differences from that used on tractors of previous models:

The clutch is double-disc, reinforced, housed in a rigid housing.
The rear axle is equipped with wheel and planetary gearboxes. Electro-hydraulic differential control system, with possible modes: automatic, on, off.
The brakes are dry, three-disc. It is possible to equip with multi-disc brakes, which are mounted on the drive gear shafts. This design of brakes is called “wet” because they work in oil.
The final drive and rear axle axle shafts are reinforced, allowing the use of heavier and more powerful attachments.

Front axle. It is also a leading one, it can be of a planetary type, or a beam-coaxial one. Equipped with planetary wheel gearboxes, double-support pivot units, a reliable reinforced beam, as well as hydraulic cylinders for the steering mechanism.

Wide front wheels, together with a reinforced axle beam, provide a reliable base for mounting front attachments, which significantly expands the functionality of the machine.

Important Factors

The modernizations of this model MTZ-5L and MTZ-5M differed in the features of the electrical equipment system and engine starting, and the modifications MTZ-5LS and MTZ-5MS were equipped with a half-track and were intended for work on heavy soils. Several years ago, the designers of the Minsk Tractor Plant presented to the European public a new model Belarus-3023, which was presented at the agricultural exhibition AGRITECHNICA, held in 2009 in Hannover and immediately received a silver medal from the German Agricultural Partnership.

Peculiarities

Another device that expands the functionality of the model is a hinged mechanism that allows you to mount additional equipment on the machine in various positions, taking into account the type of its fastening elements. I can assume that the degree of loading of a diesel power plant is determined by the ratio of its power and the power consumed by the connected device.
