ABSTRACT:
In order to start an engine, a crankshaft is first rotated reversely by a target amount of the reverse rotation and then rotated forwardly. When the crankshaft is rotated reversely, the residual gas is sucked from the exhaust passage into the combustion chamber, and residual gas is discharged from the combustion chamber into the intake passage. Next, when the crankshaft is rotated forwardly, the residual gas is sucked from the intake passage into the combustion chamber together with air, and burnt in the combustion chamber. The target amount of the reverse rotation is set to generate the backward gas flow from the combustion chamber to the intake passage in all cylinders, or to generate the backward gas flow from the exhaust passage through the combustion chamber to the intake passage in at least one cylinder.
