Abstract
A fuel injection system for an internal combustion engine in which the intake air flow is measured and a corresponding electrical signal is generated which governs a pressure control unit so as to modify the fluid pressure acting on a fuel-metering slide-valve piston, displacing it against restoring forces. The axial displacement of the slide-valve piston changes the flow aperture in adjacent metering slits and thus governs the rate of fuel flow to the injection valves of the internal combustion engine and maintains a desired fuel-air ratio.
