ABSTRACT:
Disclosed herein is a control apparatus for a spark-ignition engine that is capable of avoiding knocking at the time of high-load operation. With this control apparatus, a residual-gas suction unit or the like is not used, an exhaust gas does not deteriorate due to injection in a compression stroke, and a thermal efficiency also does not decrease. An engine control apparatus (ECU)20is used for the control of a direct-injection type spark-ignition engine. During the high-load operation of the spark-ignition engine, the ECU20injects fuel a plurality of times. In addition, the ECU performs first fuel injection toward internal EGR that exists in a combustion chamber of the spark-ignition engine.
