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, a pressure control valve connected to the control pressure conduit and further conduits for connecting the pressure control valve to the suction tube of the engine downstream of the butterfly valve and between the air sensing element and the butterfly valve. With this structure it is possible to alter the restoring force mentioned above so that a properly proportioned fuel - air mixture is achieved for various load changes of the internal combustion engine.
