Fuel Delivery System: Injectors
An electromagnetic, top feed fuel injector is installed in each cylinder inlet tract of the inlet manifolds. See Fig 1. A common fuel rail supplies the injectors with fuel from a returnless fuel delivery system. The fuel in the fuel rail is maintained at a pressure of 3.5 bar (50.75 psi) by a pressure regulator incorporated in the fuel filter unit on the side of the fuel tank. A Schrader valve is installed in the fuel rail, to the rear of injector No. 7, to enable the fuel pressure to be checked.
