吸気弁エンジン。 A main intake port and a sub-intake port are opened in the combustion chamber of one cylinder, and main and width intake valves are arranged in each of the main and sub-intake ports, respectively, and the sub-intake port is opened and closed according to the engine load. In a multi-intake valve engine, in which an intake control valve that can control the width of the intake valve is disposed, and a fuel injection valve is disposed between the intake control valve and the sub-intake valve, the width of the intake valve is adjusted to open and close according to engine speed and load. The opening/closing timing of the auxiliary intake valve can be changed at low rotation speeds,
A dual intake valve engine characterized in that the opening/closing timing of the main intake valve is set later than the opening/closing timing of the main intake valve when the load is low, and the timing is set close to the opening/closing timing of the main intake valve when the rotation is high and the load is high.
