April 5, 2006
Control method and apparatus for a direct injection spark ignited internal combustion engine, the internal combustion engine comprising a fuel injection valve configured to perform an injection of fuel into an engine cylinder and a spark plug; during a super retard combustion an ignition through the spark plug takes place at a timing after a compression top dead center, and at least once fuel injection is carried out in which the injection of fuel is started at a timing after the compression top dead center and before the ignition, during a cold start phase of the engine; and execution of the super retard combustion is inhibited for a predetermined interval of time immediately after the cold start of the engine.
