ABSTRACT:
A fuel injection system for externally ignited internal combustion engines in which a fuel metering and distributing valve is controlled by an air sensing element disposed in the air suction tube of the engine and by structure which is adapted to alter the restoring force exerted on the air sensing element through the fuel metering and distributing valve. The noted structure includes a control pressure conduit, an uncoupling throttle disposed between a fuel supply conduit and the control pressure conduit, at least one electromagnetic valve disposed in the control pressure conduit for varying pressure in the control pressure conduit in dependence on at least one operating parameters of the engine, at least one pressure regulating valve also serving to vary the pressure in the control pressure conduit, and a storage element for hydraulic integration during pressure changes in the control pressure conduit. The storage element, the electromagnetic valve and the pressure regulating valve are disposed in series in the control pressure conduit downstream of the uncoupling throttle, and the restoring force is generated by the fuel pressure downstream of the uncoupling throttle.
