Control method for an internal combustion engine and electronic control apparatus therefor.

摘要

A method of controlling the operation of an internal combustion engine is performed by the steps of detecting operational conditions of the engine (Q, theta , Tw, K, P), and determining the required amount of fuel (Pinj) to be fed to each of the cylinders based upon the number of engine revolutions and the amount of intake air received before the fuel injection valve is opened. The method detects the actual amount of intake air (AFMQa) in the suction stroke of a cylinder (1) of concern after the fuel injection valve (16) is opened and the ignition timing (18) is controlled in dependence upon the actual amount of intake air. An electronic control apparatus for performing said method is also disclosed. <IMAGE>
