Abstract
A fuel supply control system for an engine has an engine speed sensor for producing an engine speed signal and a sensor for sensing temperature of coolant and for producing a coolant temperature dependent on the temperature signal. A predetermined fuel cutoff engine speed, above which bouncing of intake and exhaust valves of the engine occurs, is set in accordance with the coolant temperature to a value which increases with increase of the temperature. When engine speed exceeds the fuel cutoff engine speed, the fuel supply is cut off.
