Abstract
A fuel supply control system for internal combustion engines properly controls the additional fuel supply at high speed operation and full load operation of the engine without causing overheating of the exhaust gas purifying device of the engine. The fuel supply control system includes a throttle switch for generating a load detection signal when the throttle valve is at its substantially full open position indicative of the heavy load condition of the engine and includes a high speed detecting device for generating a high speed detection signal when the amount of air sucked into the engine or when the intermittent signals from an ignition device exceeds a predetermined amount. In response to at least one of the detection signals, the additional fuel is supplied to the engine.
