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 dining 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.

Claim (Index 1):
A control device for an internal combustion engine, the internal combustion engine including a plurality of cylinders, a plurality of intake ports, a plurality of exhaust ports, a plurality of intake valves, a plurality of exhaust valves, a plurality of fuel injection valves, and an exhaust valve stop mechanism, the intake ports being configured to communicate with the cylinders from an intake passage of the internal combustion engine, respectively, the exhaust ports being configured to communicate with the cylinders from an exhaust passage of the internal combustion engine, respectively the intake valves being configured to open and close the intake port communicating with the cylinders, respectively, the exhaust valves being configured to open and close the exhaust port communicating with the cylinders, respectively, and the feel injection valves being configured to inject fuel into the cylinders, respectively, the exhaust valve stop mechanism being configured to selectively stop the exhaust valves of the exhaust ports of some cylinders of the cylinders in a valve-closed state, the control device comprising:\n an electronic control unit configured to\n control the fuel injection valves so as to inject the fuel into the some cylinders at least during a period of time of a compression stroke or an expansion stroke of the some cylinders, \n 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 \n 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.
