Patent ID: 8875680

Claim:
A control device for an internal combustion engine having a fuel injection valve which injects a fuel into an intake port, and an exhaust valve which can be stopped in a closed state for each cylinder, comprising: an exhaust valve control unit which stops the exhaust valve of a cylinder in the closed state when the cylinder before initial explosion is in an exhaust stroke; a fuel injection valve control unit which causes the fuel injection valve of the cylinder in which the exhaust valve is stopped in the closed state in the exhaust stroke to inject a fuel for initial explosion so that an injection time is before opening timing of an intake valve or coincides with the opening timing; and an ignition control unit which stops ignition of the cylinder until a plurality of cycles elapse after the fuel for initial explosion is injected in each cylinder before initial explosion, wherein the exhaust valve control unit stops the exhaust valve of the cylinder in the closed state until the plurality of cycles in which the ignition is stopped elapse, and the ignition control unit is configured to perform a fail safe function designed to execute ignition of the cylinder at an ignition timing immediately after the exhaust valve of the cylinder opens due to an abnormality of the exhaust valve control unit even though the plurality of cycles in which the ignition is stopped has not elapsed.
