When a change is made in the fuel injection ratio, the proper ignition timing setting means selects one of a proper ignition timing value before the change and a proper ignition timing value after the change that is on the retard side and sets the ignition timing at the selected proper ignition timing value in at least a predetermined period of time after the change.",
