The power supply system of the diesel engine and turbocharger
The car is a diesel engine with direct fuel injection and turbocharging. Direct injection fuel system is a joint development of firms Bosch, Audi and Volkswagen. A special feature of this system is the use of electronically controlled injectors, which in one stroke is activated twice. First, the cylinder is injected a small amount of fuel (precharge). After the pre-charge combustion is injected main portion of the fuel. Through this process it softens combustion reduced exhaust emissions and noise.
If any sensor or system component failures are detected, they will be fixed by the registrar of faults, which will later establish exactly these faults to the service station using a special diagnostic equipment.
