ABSTRACT:
A control device for a cylinder injection type internal-combustion engine restrains the deterioration of combustion in the cylinder injection type internal-combustion engine which implements stratified charge combustion at a delicate fuel injection timing and a delicate ignition timing. The control device is equipped with a combustion state detector for detecting the deterioration of combustion in the internal-combustion engine, and a device for restraining the deterioration of combustion in the internal-combustion engine by gradually changing at least one parameter among the amount of exhaust gas to be recirculated, an ignition timing, and an air-fuel ratio when the combustion state detector has detected the deterioration of combustion in the internal-combustion engine.
