ABSTRACT:
A multi-cylinder fuel injection engine has a respective fuel injector nozzle associated with each cylinder and has one injector pump which supplies fuel to all of the nozzles. The engine includes a rotatable drive element having a plurality of cams which correspond in number to the number of cylinders, which are uniformly angularly distributed thereon, and which successively act on a delivery element of the pump as the drive element is rotated. A shut-off member is associated with each injector nozzle and can close the fuel supply line to the nozzle's injection orifice, the shut-off member being controlled in dependence on a control criteria which determines the injection timing point. Fuel is thus supplied to all nozzles, but can only flow through a respective one of the nozzles which has its shut-off member moved in response to the control criteria to an open position.
