6.3. Power supply system of diesel engines

Principles of functioning of control systems of diesel engines

During the operation of the diesel engine in its cylinders clean air which contracts to high pressure is soaked up. At the same time air temperature rises higher than temperature of ignition of diesel fuel. Fuel is injected into the cylinder with some advancing and self-ignites. Thus, spark plugs for ignition of fuel in the diesel engine are not used.

On the cold engine 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 glow plug heating the combustion chamber is established. Duration of heating depends on surrounding temperature and is regulated by the control unit of the engine and the relay of preliminary warming up.

Before getting to TNVD fuel is purified of pollution and water in the fuel filter. Therefore it is important to delete water from the fuel filter or to replace it according to requirements of the schedule THAT (see the Head Nastroyki and routine maintenance of the car).

For increase in power on some engines the turbo-supercharging is used.

Diesel engines are operated the electronic system similar to a control system of petrol engines (see the Section Power Supply System of Petrol Engines).
