ABSTRACT:
A fuel injection system for regulating fuel flow so as to maintain a desired fuel-air mixture in a mixture compressing, externally ignited internal combustion engine includes the air intake suction tube of the internal combustion engine. A measuring device is provided for measuring the quantity of air passing through the air intake suction tube. A pressure control device, responsive to output from the measuring device produces, as its output, a variable fluid pressure head. At least one fuel metering valve is responsive to the output from the pressure control device. This fuel metering valve has a movable member, preferably a slide valve piston, which is actuated in two control directions. The fuel metering valve functions to meter out fuel, in desired proportion, into the quantity of air streaming through the suction tube.
