  • Fuel supply control system for internal combustion engines
    Patent number: 4966111
    Abstract: A fuel supply control system for an internal combustion engine, wherein when the engine is at idle, a correction value is determined based on a difference between a desired idling engine rotational speed and an actual engine rotational speed, and an amount of fuel to be supplied to the engine is corrected by the determined correction value. Correction value-changing means sets a rate of change in the correction value relative to a change in the difference to a greater value when the detecting means detects that the engine means is not engaged with the transmission of an automotive vehicle, and to a smaller value when the detecting means detects that the engine is engaged with the transmisison.
