Control apparatus and method for inner cylinder direct injection spark ignited internal combustion engine

A control method for an inner cylinder spark ignited internal combustion engine, the engine comprising:

• a fuel injection valve configured to directly inject fuel into an inside of an engine cylinder;
• and a spark plug, the control method comprising:
• executing 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;
• setting the ignition timing after the compression stroke top dead center and injecting 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
• setting the ignition timing before the compression stroke top dead center and injecting 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.
