US 7,212,910 B2 · Control apparatus of direct injection internal combustion engine

Abstract

The present invention provides a control apparatus of a direct injection internal combustion engine used in an idling stop vehicle or the like, which can reduce residual fuel generated in a combustion chamber in an engine stop time, and prevent deterioration of exhaust performance and deterioration of exhaust gas performance (A/F control precision) at the time of engine restart. The control apparatus includes an automatic stop control device for automatically stopping an internal combustion engine upon satisfaction of a predetermined automatic stop condition, and at least one of a fuel injection control unit which corrects fuel injection and an air-flow amount control unit which corrects an air-flow amount. Upon satisfaction of the predetermined automatic stop condition, at least one of fuel injection correcting control by the fuel injection control unit and air-flow amount correcting control by the air-flow amount control unit is performed.
