ABSTRACT:
A fuel supply system for internal combustion engines includes a fuel reservoir adjacent the induction manifold from which fuel is aspirated depending on pressure differences in two separate regions of the manifold.
An electric controller reacts to engine rpm and exhaust gas composition signals to actuate electromagnetic valves in the air conduits leading from the manifold to the fuel reservoir. Various valve opening schedules can be performed depending on the desired fuel mixture.
