General
A Siemens common rail fuel injection system is used on the Stage IV 1.8L Duratorq-TDCi
(Kent) 75PS, 90PS and 110PS diesel engines.
Within the fuel pump there is an integral fuel transfer pump which draws the fuel from the
fuel tank to the fuel pump.
A fuel metering valve is located in the supply port to the high-pressure chamber of the fuel
pump. The fuel metering valve varies the quantity of fuel supplied to the fuel rail and fuel
injector(s), in relation to the driving conditions.
The fuel is supplied at high-pressure to the fuel rail and to the fuel injectors ready for
injection. Depending on engine operating conditions, the fuel injection pressure varies
between 200 bar and 1600 bar.
Fuel system pressure is measured using an FRP sensor located in the fuel rail. The FRP
sensor converts the fuel system pressure into a voltage signal. This voltage signal acts as
an input signal to the powertrain control module (PCM) for calculation of the fuel injection
quantity.
