ABSTRACT:
A fuel injection system for controlling a mixture-compressing, externally ignited internal combustion engine which includes a fuel apportionment valve controllable by means of an air flow rate meter, with the fuel pressure upstream of the apportionment point being variable by means of a pressure regulating valve having a movable valve member which separates two chambers connected by a throttle point, and wherein the fuel pressure upstream of the fuel apportionment valve is exerted on one side of the movable valve member, and the force of a spring and a control pressure, which is variable by means of a control element in accordance with operating characteristics of the internal combustion engine, are exerted on the other side of the movable valve member to thereby intervene easily in order to vary the fuel-air mixture using small control forces.
