Abstract

A fuel injection system for internal combustion engines includes an airflow measuring member which actuates a fuel metering valve assembly. The pressure drop across this valve assembly may be changed by changing the restoring force on the movable control slide therein. The restoring force is provided by pressurized fluid, for example fuel, and the pressure of this fluid can be adjusted by an electro-magnetic pressure modulator, in turn controlled by an electronic controller responsive to engine conditions as sensed by transducers. A pressure limiting valve further influences the control fluid pressure.
