Abstract
The speed of rotation and the angular position of the rotating part (2, 3) of the engine (1) are measured continuously, and the fuel injection is cut off at predetermined speed and angular position values of the rotating part (2, 3) in order to stop the engine in a predetermined position that facilitates restarting the engine. In order to restart the engine, using a starter (4), fuel is injected into at least one cylinder of the engine when the piston moving in the cylinder is in a determined position. The spark ignition and/or fuel injection is interrupted at predetermined speed and angular position values of the rotating part (2, 3) of the engine (1), and fuel is injected into at least one cylinder of the engine (1) during the last revolution of the engine before stopping. In order to restart the engine, ignition is carried out in at least one cylinder, the piston of which is in the compression position at the moment when the engine (1) stops.
