Abstract:
1. A control apparatus for an inner cylinder direct injection spark ignited internal combustion engine, comprising: a fuel injection valve configured to directly inject fuel into an inside of an engine cylinder; a spark plug; and a control unit configured to execute a super retard combustion to set an ignition timing after a compression stroke top dead center and to inject at least part of the fuel before the ignition timing and after the compression stroke top dead center when a fuel pressure is high, configured to set the ignition timing after the compression stroke top dead center and to inject at least part of the fuel before the compression stroke top dead center to decrease a fuel injection quantity when the fuel pressure is sufficient, and to set the ignition timing before the compression stroke top dead center and to inject all quantities of the fuel before the compression stroke top dead center during an interval which is immediately after an engine start and in which the pressure of fuel is relatively low.
