Abstract (en)
In the present invention, when it is determined that combustion failure occurs in a stop-state compression-stroke cylinder (12A) of an engine (1) after ignition during a reverse-rotation operation, a starter motor (36) is activated to drive the engine (1) in a normal rotation direction. In this process, combustion is produced in a stop-state expansion-stroke cylinder (12B), and additional fuel is injected into the stop-state compression-stroke cylinder (12A) which undergoes a compression stroke and having an in-cylinder pressure being gradually increasing, so as to facilitate lowering the in-cylinder pressure based on a latent heat in the cylinder and allow an air-fuel ratio to become overrich to reliably avoid self-ignition in the end gas of a combustion chamber.
