載の複吸気弁エンジン。[Claims for Utility Model Registration] 1. A first intake port that is always open to generate a swirl in the intake air supplied into the combustion chamber, and an intake control valve that is opened only in the high-load, high-speed operating range of the engine; It is equipped with a second intake port that supplies straight intake air into the room, and a third intake port that is provided with a fuel injection valve.
and a third intake port respectively to the first, second and third intake ports.
In a dual intake valve engine, each of which opens into a combustion chamber through an intake valve of the third intake port, the opening of the third intake port to the combustion chamber is connected to the first intake port directly below the swirl flow generated by the first intake port. A dual intake valve engine characterized by having a dual intake valve installed at a position facing the opening of an intake port. 2. The openings of the first intake port and the second intake port are arranged in a Siamese port arrangement, and there is one exhaust port, and the opening to the combustion chamber is set at the opening of the first intake port and the second intake port with respect to the center of the combustion chamber. 2. The dual intake valve engine according to claim 1, wherein the dual intake valve engine is provided so as to be located on the diagonal side of the opening of the first intake port.
