ABSTRACT:
An fuel supply amount control system for an internal combustion engine comprises an evaporative fuel passage extending between the fuel tank and the intake system of the engine, and a control valve arranged across the evaporative fuel passage, for opening and closing the evaporative fuel passage. A pressure sensor detects pressure within the fuel tank. The opening of the control valve is controlled such that the interior of the fuel tank is held under negative pressure. After termination of negative pressurization of the fuel tank, the amount of fuel supplied to the engine is increased according to an amount of increase in the pressure within the fuel tank detected by the pressure sensor.
