Zusammenfassung:	PROBLEM TO BE SOLVED: To stably, surely and quickly restart a compression self-ignition type engine by single compression starting even if the stop position of a piston of a stop-time compression stroke cylinder is close to a top dead center when restarting the compression self-ignition type engine, namely, there is a factor unfavorable to the ignition of fuel injected to the stop-time compression stroke cylinder.SOLUTION: In the case of restarting the engine (YES in a step S21), when performing fuel injection to the stop-time compression stroke cylinder which is in a compression stroke when the engine is stopped to start the engine by single compression starting (YES in a step S22), pre-injection for pre-combustion is performed before performing main injection for main combustion, and as the stop position of the piston of the stop-time compression stroke cylinder is closer to the top dead center, the total injection amount of the fuel for pre-injection is increased more (step S23).
