Abstract:
1. An engine control apparatus for an engine having an injector in each cylinder to perform fuel injection from the injector a predetermined number of times for each cylinder combustion, for controlling the timing of fuel injection from the injector and the ignition timing, wherein the engine control apparatus provides control means which, upon combustion mode changeover from a first combustion mode in which fuel injection is performed at least once for each cylinder combustion to a second combustion mode in which fuel injection is performed a greater number of times with a larger intake air volume than the first combustion mode, performs the steps of changing, in the first combustion mode, to a target intake air volume required in the second combustion mode; retarding the ignition timing; changing to the second combustion mode; and further retarding the ignition timing.
