Zusammenfassung:PROBLEM TO BE SOLVED: To prevent combustion noises from increasing when switching from spark ignition combustion to compression ignition combustion.SOLUTION: When switching from a spark ignition mode to a compression ignition mode, a controller (PCM 10) switches the mode to the compression ignition mode after performing a transition combustion mode that achieves a combustion gas temperature lower than a combustion gas temperature during spark ignition combustion prior to the mode switching.
