摘要： PROBLEM TO BE SOLVED: To stabilize combustion in a spark-ignition type gasoline engine 1 even when combustion is greatly delayed for the purpose of catalytic activity.SOLUTION: A controller (PCM 10) controls a fuel pressure variable mechanism (a high-pressure fuel supply system 62) so that the fuel pressure becomes higher compared to a case when the catalyst is active, when the operating state of an engine body is in a low-load range in a low-speed range and in the catalyst active mode in which the catalyst (a direct catalyst 41, an under-foot catalyst 42) is inactivated. The controller further drives an in-cylinder injection valve (a direct injector 67) so as to include at least fuel injection to be executed in the expansion stroke, and drives an ignition plug 25 for ignition after injecting the fuel.
