ABSTRACT:
A fuel injection system for substantially continuous injection into a suction tube of a mixture-compressing, spark plug-ignited internal combustion engine includes a fuel line and a fuel pump. A measuring member and an arbitrarily actuatable throttle flap are disposed, one behind the other, in the suction tube. The measuring member is displaceable in proportion to air quantity and against a resetting force which is normally constant but which is changeable in dependence on engine parameters. A metering valve having a movable part is disposed in the fuel line and coupled to the measuring member. The measuring member actuates the movable part for metering fuel quantity in desired proportion with respect to air quantity. A regulating mechanism, which includes a piston, is actuated in dependence on fuel pressure prevailing downstream from the fuel pump. The piston acts against the force of a spring.
