とを特徴とする気筒数制御エンジン。In a light load operating range, in a four-cylinder internal combustion engine that is equipped with two inactive cylinders that have means for regulating the opening of the intake valve and exhaust valve, and two operating cylinders that are always in operation, during operation and at rest. Accordingly, the valve timing of the intake and exhaust valves of the cylinder on the idle side is changed, and when the cylinder is idle, the intake valve is kept closed, and the exhaust valve is opened only during a part of the piston's upward stroke or downward stroke, and the valve timing is changed between the top dead center and the bottom stroke. A cylinder number control engine characterized by the valve being closed at dead center.
