Abstract:
An internal combustion engine comprising:electromagnetic driving valve mechanisms that drive at least one of intake and exhaust valves of the internal combustion engine in their opening and closing directions by means of an electromagnetic force; a transmission capable of changing a gear change ratio; a valve controller that controls opening characteristics of at least one of the intake and exhaust valves in association with operation states of at least one of the electromagnetic driving valve mechanisms and the transmission; a determining portion that determines a torque schedule of the internal combustion engine based on a target engine torque required of the internal combustion engine and an accelaration-deceleration shock absorbing torque; and a target cylinder torque calculator that calculates a target cylinder torque of cylinders of the internal combustion engine in accordance with the torque schedule, wherein the valve controller controls opening characteristics of at least one of the intake and exhaust valves based on the target cylinder torque.
