摘要

A closed loop engine control system in which: the fuel delivery and ignition timing functions of the engine are responsive to a measurement of the engine's instantaneous rotational velocity (1004). Signals indicative of the profile of each torque impulse imparted to the rotary output member of the engine from the burning of an air/fuel mixture in the engine's combustion chambers are generated and electrically analysed to detect perturbations caused by deviations of at least two different engine operational parameters from desired values. Feedback correction signals indicative of the magnitude of the detected perturbations are generated (1007, 1008, 1009) and used to correct the fuel delivery and ignition timing functions of an engine control means to minimize the differences between the actual values of the operating parameters and the desired values. The correction signals may be applied to the engine control means through a state variable matrix which provides for the control of at least one engine parameter as a function of at least two different correction signals.
