ABSTRACT:
An electrically controlled fuel injection pump for internal combustion engines, in particular for direct fuel injection in engines having externally supplied ignition contains a plurality of pump pistons driven by a single common cam. The pumping quantity of fuel is delivered by pumping pistons is controlled via a rotary slide valve to the injection nozzles at the injection sites of the engine, wherein the quantity control is effected by an electrically controlled valve. An axial conduit of the rotary slide which discharges into control bores or control grooves distributed over the circumference of the rotary slide and cooperates with the pump work chamber and the pressure lines to the injection sites and is adjoined by at least one further control bore or control groove which communicates with a pressure reservoir. By this means, a preinjection, separate from a main injection, is made possible at the top dead center charge change.
