摘要： PROBLEM TO BE SOLVED: To reduce a load range where an intake air charging amount is needed to be reduced as far as possible by improving combustion stability in a spark-ignition mode, in a spark-ignition type gasoline engine 1 that switches a mode between a compression-ignition mode for executing compression-ignition combustion, and the spark-ignition mode for executing spark-ignition combustion.SOLUTION: A controller (a PCM10) is set to the compression ignition mode in a low-load range, and set to the spark-ignition mode in which the fuel pressure is increased and fuel injection is performed within a retard period from the late stage of compression stroke to the early stage of expansion stroke, in a high load range. In the spark ignition mode, external EGR control is performed. The controller further sets the EGR ratio to be higher, in the range equal to or lower than the predetermined load in the spark ignition mode, than the EGR ratio in the range higher than the predetermined load, and also performs charging amount control to reduce an intake air charging amount to be less than that in the compression-ignition mode.
