ABSTRACT:
A method and apparatus for controlling an internal combustion engine having at least one cylinder adapted to intake, during each intake stroke of the cylinder, fuel supplied in a plurality of instalments. Means is provided for controlling the amount of fuel supplied to the engine. Adjustments of the control means are produced by generating electrical signals indicative of engine operating conditions, and, with a digital computer, repetitively calculating values corresponding to settings of the control means. The digital computer is programmed to calculate a basic value from an algebraic function describing a desired relationship between the engine conditions and the basic value, detect engine acceleration and deceleration conditions from changes in the engine conditions, and add a positive or negative value to the calculated basic value when the engine is accelerating or decelerating to correct the calculated basic value for the detected acceleration and deceleration conditions.
