ABSTRACT:
A fuel supply system for an internal combustion engine includes an airflow metering device in the induction manifold which directly actuates a fuel metering valve formed by cooperating parts of the airflow meter bushing and the shaft around which it pivots. A differential pressure valve holds the pressure drop across the fuel metering aperture constant. Bimetallic springs are provided to exert temperature dependent forces on the diaphragm in the differential pressure valve to increase the differential pressure when the engine is cold.
