Abstract
An internal combustion engine includes two intake side solenoid driving valve mechanisms for opening and closing intake valves by cooperation of an electromagnetic coil and a spring, and/or two exhaust side solenoid driving valve mechanisms for opening and closing exhaust valves provided on each cylinder. A controller commands a driving circuit to cause the valve-opening timing of the exhaust valves or the intake valves to be different.
