D-260: engine of a wide range of applications

The D-260 is an engine that has a wide range of applications. The field of application of these diesels is a place with free access to air. These motors are used to operate at an ambient temperature of +40 to -45 degrees Celsius. In the article, we will talk more about this engine in more detail, we will understand its scope, tell about all the characteristics of the unit and talk about the causes of the most frequent breakages.

Application area of the D-260 engine

Diesel D-260 - the engine, which is used as a power unit on wheeled tractors, tractors with caterpillar propulsors, forage harvesters, power tools, and also on other transport-technological machines. The design of these engines provides a long period of operation without major overhaul, subject to the requirements of the operating and storage manual for the D-260 engine. This can explain the popularity of the installation for cars of the GAZ and ZIL families. It is installed on them as a power unit. The D-260 is the engine of a wide range of uses.

Characteristics of the engine

The technical characteristics of the D-260 engine are as follows: a four-stroke diesel with a turbocharger, with direct fuel injection, having six vertically arranged cylinders with a total working volume 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 design compression ratio of the D-260 engine is 15, the developed rated output is 114 kilowatts at a crankshaft rotation speed of 2100 rpm with a specific fuel consumption of 220 g / kWh, the weight of the D-260 (engine) is 650 kg.

Major breakdowns

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

• Breakages in the starting device;
• Violation of integrity in the electrical circuit or faulty coil of the starter relay coil, the presence of a break in the stator windings;
• In the fuel system of the engine is air;
• Failure of the fuel supply system as a whole;
• In the cold season with the presence of water in the fuel system and its freezing;
• Cold engine;
• Blockage of the hole in the fuel cap, lack of sufficient compression in the cylinders;
• Damage to valve springs;
• Faulty valves.

In the event that a short-term diesel engine starts and then stops, this is usually due to the following reasons:

• Leakage of the fuel supply system;
• Failure of high-pressure pump or indicates a blockage of the exhaust tract.

If there are the following signs: light exhaust from the pipe, unstable engine operation and lack of full power, can speak of such malfunctions as clogging of the fine fuel filter, presence of water in the fine filter, presence of incomplete course of the rail, air intake in the pipeline section of the smoke limiter , Destruction of the diaphragm, or indicates that the amount of fuel supply does not meet the standards.
