Abstract
Even when an engine rotates in the inverse direction immediately before stopping, the engine can be accurately activated. In an engine which injects fuel sequentially on the basis of an ignition order of each cylinder, a crank angle of the terminal position of the engine is stored. On the first fuel injection timing after engine activation, fuel is simultaneously injected into a cylinder which is determined from the terminal stored position and into a cylinder in a fixed positional relationship with the first cylinder. In this way, even when an engine rotates in the inverse direction immediately before stopping, fuel injection can be accurately performed at least on a cylinder into which fuel should be injected and the engine can be accurately activated.
