Document Type and Number:

Japanese Patent JP3216139

Kind Code:

B2

Abstract:

This invention relates to a control system for an in-cylinder injection internal combustion engine, which performs control of the timing of fuel injection, the timing of ignition and an EGR rate. It is an object of the present invention to assure the stability of combustion in an in-cylinder injection internal combustion engine and also its exhaust gas cleaning performance while promoting an improvement in gas mileage by performing injection in compression strokes. The control system is provided with a fuel injection valve (4) for directly injecting fuel into a combustion chamber (4) of an internal combustion engine, a spark plug (7) arranged in a combustion chamber (4), an EGR valve (13) arranged in an EGR passage (12), fuel injection timing control means (21) for controlling a fuel injection timing of the fuel injection valve (5) on a basis of a preset target fuel injection timing, ignition timing control means (22) for controlling an ignition timing of the spark plug (7) on a basis of a preset target ignition timing, exhaust gas recirculation rate control means (25) for controlling an opening of the EGR valve (13) on a basis of a preset target EGR rate, and misfire determination means for detecting a burning fluctuation, whereby upon detection of a burning fluctuation, the target fuel injection timing, the target ignition timing and the target EGR rate are retarded or decreased.
