摘要： Upon refreshing a catalyst (25) in steps SA2 to SA6, the air-fuel ratio of each combustion chamber (4) of an engine (1) is dither-controlled to periodically vary to the rich and lean sides of a target value (A/F=15 to 16) in steps SA16 and SA17. In step SA15, an injector (7) divisionally injects fuel in two injections within the period from the intake stroke to the compression stroke of each cylinder, thus accomplishing weakly stratified combustion. In step SA18, the opening of an EGR valve (27) is controlled to recirculate a large amount of exhaust gas to an intake path (10) so as to achieve around 40% EGR ratio.

摘要： A control device for controlling a direct injection engine provided with an injector for injecting fuel directly into a combustion chamber in a cylinder thereof and a throttle valve is switchable between a stratified charge combustion mode and a uniform charge combustion mode. The control device predicts switching to the uniform charge combustion mode based on a change in the target load Piobj during engine acceleration in the stratified charge combustion mode, and corrects the target load Piobj so that the opening of the throttle valve approaches the opening suited for the uniform charge combustion mode prior to the switching to the uniform charge combustion mode when such combustion mode switching has been predicted. This control device prevents torque shock due to the combustion mode switching during engine acceleration without causing a deterioration in fuel economy or in vehicle acceleration performance.
