D-260: engine for a wide range of applications

D-260 is an engine that has a wide range of applications. The scope of these diesel engines is places with free access to air. These motors are used to operate at ambient temperatures from +40 to -45 degrees Celsius. In the article we will talk about this engine in more detail, deal with its scope, talk about all the characteristics of the unit and talk about the causes of the most frequent breakdowns.

Scope of the D-260 engine

Diesel D-260 is an engine that is used as a power unit on wheeled tractors, caterpillar tractors, forage harvesters, power vehicles, as well as on other transport and technological machines. The device of these engines provides for a long period of operation without major repairs, subject to the requirements of the operation and storage manual for the D-260 engine. This canexplain the popularity of installation on cars of the GAZ and ZIL families. It is installed on them as a power unit. D-260 - engine for a wide range of applications.

Engine specification

The technical characteristics of the D-260 engine is as follows: a four-stroke turbocharged diesel engine with direct fuel injection, having six vertically arranged in a row cylinders with a total displacement of 7.12 liters. Cylinders work in the following sequence: first-fifth-third-sixth-second. The crankshaft rotates clockwise (to the right), the cylinder diameter is 0.11 meters, and the piston stroke is one hundred and twenty-five millimeters. The calculated compression ratio of the D-260 engine is 15, the developed rated power is 114 kilowatts at a crankshaft speed of 2100 rpm with a specific fuel consumption of 220 g / kWh, the weight of the D-260 (engine) is 650 kg.

Main breakdowns

If this engine does not start, then this may be due to the following breakdowns:

  • breakdown in the starting device;
  • violation of integrity in the electrical circuit or the winding of the starter relay coil is faulty, the presence of a break in the stator windings;
  • there is air in the engine fuel system;
  • breakdown of the fuel supply system as a whole;
  • in the cold season when there is water in the fuel system and it freezes;
  • cold engine;
  • Clogged holes in the lidfuel tank, lack of sufficient compression in the cylinders;
  • damaged valve springs;
  • valve failure.

If there is a short-term start of the diesel engine with its subsequent stop, then this is usually due to the following reasons:

  • leakage of the fuel supply system;
  • failure of the high pressure fuel pump or indicates a clogged exhaust tract.

If there are the following signs: light exhaust from the pipe, unstable engine operation and lack of full power, it may indicate malfunctions such as a clogged fine fuel filter, the presence of water in the fine filter, the presence of incomplete rack travel, air intake on the pipe section of the smoke limiter, the destruction of the diaphragm, or indicates that the amount of fuel supply does not meet the standards.
