ABSTRACT:
A fuel supply system of a type for use with an internal combustion engine employs a valve assembly and a circuit for controlling the valve assembly to supply fuel to the engine at a greater or lesser rate respectively in response either to initial closure of an ignition switch when the engine is cold, according to one mode of operation, and in response to acceleration of the engine, according to another mode of operation. The fuel supply system serves to include means for preheating or vaporizing the fuel supplied to the engine.
