Abstract
Provided is a control device for an internal combustion engine. The internal combustion engine includes cylinders, intake ports, exhaust ports, intake values, exhaust valves, fuel injection valves, and an exhaust valve stop mechanism. The control device includes an electronic control unit configured to control the fuel injection valves so as to inject the feel into the some cylinders at least during a period of time of a compression stroke or an expansion stroke of the some cylinders, control the exhaust valve stop mechanism so as to stop the exhaust valves of the exhaust ports of the some cylinders in a valve-closed state, and control the intake valves so as to open the intake valves at least during a period of time of an intake stroke of the some cylinders such that exhaust gas is recirculated to each of the cylinders via the intake ports of the some cylinders.
