ABSTRACT:
A method of controlling fuel mixture supply to an internal combustion engine having fuel injection system in which the quantity of fuel is metered in dependency on gas pedal position and the quantity of air is subsequently metered in dependency on the position of the throttling plate. The method employs a preliminary control with superposed extreme value regulation. For this purpose, the injection time interval or the throttle plate position are adjusted in dependency on the gas pedal position and on the rotary speed of the engine. During the operation of the engine, test cycles are continuously established and according to the reaction of the engine to the tests, the adjustment of the injection time interval and of the throttle plate position are made. The method is suitable particularly for internal combustion engine used in motor vehicles.
