ABSTRACT:
A method and apparatus for optimum control for internal combustion engines employ computing means with memory means in which the values indicative of ignition timings and air-fuel ratios of an engine are preliminarily stored in the form of maps in accordance with parameters indicative of the operating conditions of the engine. At least one cycle of ignition timing optimization processing and at least one cycle of air-fuel ratio optimization processing are performed alternately so as to control the engine at the optimum ignition timing and air-fuel ratio for minimum fuel consumption.
