ABSTRACT:
An engine includes cylinders, a sensor for detecting information related to combustion states of the cylinders. Each cylinder is provided with an ignition device, an intake valve, and an exhaust valve. The engine also includes a control apparatus that obtains the information from the sensor. Based on the information from the sensor, the control apparatus identifies a cylinder of the most violent combustion. The control apparatus controls at least one of the valve timing of the intake valves, the valve timing of the exhaust valves, and a fuel injection amount to the cylinders, thereby suppressing the combustion of all the cylinders, such that the combustion state of the identified cylinder becomes an appropriate combustion state. As for a cylinder the combustion state of which is out of a predetermined range and is a state causing misfire, the control apparatus selectively activates the corresponding ignition device to perform assisted ignition. This configuration reduces variation in the combustion states among the cylinders.
