Abstract
A fuel supply system for an internal combustion engine having at least one combustion chamber comprises a supercharger, a fuel intake passage system leading from a source of air to the combustion chamber through the supercharger. A portion of the fuel intake passage system between the supercharger and the combustion chamber is divided into first and second intake passages having incorporated therein primary and secondary throttle valves. The primary throttle valve is operatively associated with a foot-operated acceleration pedal whereas the secondary throttle is adapted to be controlled by a pressure developed inside the fuel intake passage system at a position downstream of the throttle valves. A diaphragm valve unit is utilized to control the secondary throttle valve in response to the pressure inside the fuel intake passage system at that position.
