PROBLEM TO BE SOLVED: To increase an engine control accuracy when fuel evaporative gas is purged into an intake system during the stratified combusting operation of a cylinder injection engine. SOLUTION: During the stratified combusting operation, a fuel injection amount is calculated based on a requested torque and the like and, based on the fuel injection amount, various types of control parameters are calculated. When fuel evaporative gas is purged into an intake system during the stratified combusting operation, the fuel injection amount is purge-corrected (amount reduction correction) according to the purged amount, and the control parameters (injection timing, ignition timing and the like) to be set according to the fuel injection amount (actual fuel injection amount) after the purge correction among the various types of control parameters are corrected according to the purge-corrected amount of the fuel injection amount. Thus, the control parameters to be set according to the actual fuel injection amount (fuel injection amount after purge-correction) and the control parameters to be set according to the overall fuel amount (fuel injection amount before purge-correction) supplied into the cylinders can be set to appropriate values. |
