The power supply system of diesel engine V6
The general information
At work of the diesel engine in its cylinders pure air which is compressed to a high pressure is soaked up. Thus air temperature rises above temperature of ignition of diesel fuel. Fuel is injected into the cylinder with some advancing and самовоспламеняется. Thus, spark plugs for fuel ignition in the diesel engine are not used.
On the cold engine the temperature of compressed air can not reach value necessary for ignition. In this case additional preliminary warming up is necessary. For this purpose in each cylinder the candle накаливания, heating up the combustion chamber is established. Duration of heating depends on the surrounding temperature and is regulated by the block of management of the engine and the relay of preliminary warming up.

Components of an inlet air path
Fuel is compressed to pressure necessary for injection in the fuel pump of a high pressure (ТНВД) where it moves the fuel pump from a fuel tank through the fuel filter. Pressure of injection is regulated by the engine management block.
The fuel distributive highway is applied to a supply of fuel from ТНВД to atomizers of separate cylinders.
Diesel engines cope the electronic system similar to a control system by petrol engines. Differences are listed more low.
In a control system of diesel engines the cable of management throttle заслонкой is not used, instead of it the gauge of position of a pedal of the gas, located on a support of a pedal of gas is established. Besides, it is used Д/В brake pedals (Д/В stoplights) which provides decrease in giving of fuel at single turns if the gauge of position of a pedal of gas has failed. The gauge of position of a camshaft (CMP) together with gauge CKP hands over to the block of management the information about ВМТ the piston of the first cylinder. It serves for synchronisation of the moment of ignition and sequence of ignition.
