PURPOSE:To prevent an engine stall and excessive fuel feed by detecting the engine speed change after a fixed crank angle has elapsed since the time the fuel feed is resumed from its cutoff condition and controlling the fuel feed augmentation after cutoff in response to this change. CONSTITUTION:At a step 5, whether 8 TDC signals have elapsed since the fuel cut completion time or not is judged. If it is YES, the augmentation factor after fuel cut KAFC is set to 1 at a step 6. The augmentation this time is determined in response to the engine speed change since the fuel cut completion time to the time 8 TDC signals have elaspsed. Accordingly, an engine stall and excessive fuel feed can be prevented.
