Abstract
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.
