PURPOSE:To prevent acceleration performance from declining in order to prevent unburnt component of fuel from increasing by stopping fuel supply to an engine when the engine reaches the specified deceleration operating state after the engine keeps the specified steady operating state for the specified time. CONSTITUTION:It is judged at a step 8 whether fuel cut (F/C) condition has been established. When the judged result of the step 8 is positive (Yes), it is judged at a step 9 whether the specified time tFCDLY has passed. When the judged result of the step 9 is positive, fuel cut is carried out since delay time after establish a fuel cut condition has passed. In this way, acceleration performance after gear change can be prevented from declining. Also, no surplus fuel is obtained, so that unburnt component CO and HC of refuse can be prevented from increasing.
