D-260 is an engine that has a wide range of applications. The scope of these diesels is places with free access to air. These engines are used for operation at ambient temperatures from +40 to -45 degrees Celsius. In the article we will talk about this engine in more detail, we will deal with its scope, we will talk about all the characteristics of the unit and talk about the causes of the most frequent breakdowns.
Scope of the D-260 engine
D-260 diesel is an engine that is used as a power unit on wheeled tractors, tracked tractors , forage harvesters, power tools, as well as on other transport and technological vehicles. The device of these engines provides a long period of operation without major repairs, provided that the requirements of the operating and storage manual for the D-260 engine are met. This can explain the popularity of the installation on cars of the GAZ and ZiL family. It is installed on them as a power unit. D-260 - a wide range of engine use.
Engine characteristic
The technical characteristics of the D-260 engine are as follows: a four-stroke turbocharged diesel engine with direct fuel injection, having six cylinders vertically arranged in a row with a total displacement of 7.12 liters. The cylinders work in the following sequence: first-fifth-third-sixth-second. The rotation of the crankshaft occurs clockwise (to the right), the cylinder diameter is 0.11 meters, and the piston stroke is one hundred twenty-five millimeters. The calculated compression ratio of the D-260 engine is 15, the developed rated power is 114 kilowatts with a crankshaft rotation frequency 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:
- breakdowns in the starting device;
- integrity violation in the electric circuit or the coil of the starter relay coil is faulty, the stator windings are broken;
- there is air in the engine fuel system;
- failure of the fuel supply system as a whole;
- in the cold season when there is water in the fuel system and its freezing;
- cold engine;
- clogged holes in the fuel cap, lack of sufficient compression in the cylinders;
- valve spring damage;
- valve malfunction.
In the event that a short-term start of the diesel engine occurs with its subsequent stoppage, this is usually due to the following reasons:
- leakage of the fuel supply system;
- failure of the high pressure fuel pump or indicates a clogging of the exhaust tract.
If there are the following symptoms: light exhaust from the pipe, unstable engine operation and lack of full power, it can indicate malfunctions such as clogging of the fine fuel filter, the presence of water in the fine filter, the presence of incomplete rail travel, air intake in the section of the smoke restrictor pipeline , destruction of the diaphragm, or indicates that the amount of fuel supply does not meet the standards.
