A method and apparatus for controlling an internal combustion engine. The amount of fuel delivered to the engine is controlled in direct proportion to the rate of air flow introduced into an engine cylinder. The timing of ignition of the engine in controlled based upon a difference between the actual torque actually produced on the engine output shaft and the ideal torque required on the engine output shaft at the engine speed, thereby bringing the actual torque quite close to the ideal torque.

A method of controlling an internal combustion engine having an induction passage leading to at least one cylinder for generating a torque on its output shaft, comprising the steps of: generating a first signal indicative of the speed of said engine output shaft; generating a second signal indicative of a selected engine operating parameter; calculating a first value for the rate of air flow introduced into said engine cylinder based upon said first and second signals; calculating a second value for the amount of fuel to be delivered into said engine cylinder based upon said first value, said second value being substantially in direct proportion to said first value; calculating a basic value for the timing of ignition in said engine cylinder based upon at least one of said first and second signals; calculating an output-torque correction-factor based upon at least one of said first and second signals, said output-torque correction-factor being substantially in direct proportion to a difference between an actual torque actually produced on said engine output shaft and an ideal torque required on said engine output shaft at the engine speed; modifying said calculated ignition timing basic value based upon said calculated output-torque correction-factor to provide a value for the timing of ignition in said engine cylinder, thereby bringing the actual torque close to the ideal torque.
