範囲第１項記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, the opening of the third intake port into the combustion chamber is connected to the opening of the first intake port into the combustion chamber with respect to the center of the combustion chamber. A dual intake valve engine characterized by having two intake valves arranged diagonally opposite each other. 2. Each opening of the first intake port and the second intake port is arranged as a Siamese port, and there is one exhaust port, and the opening to the combustion chamber is the opening of the first intake port. The dual intake valve engine according to claim 1, characterized in that the dual intake valve engine is provided at a position opposite to the dual intake valve engine.
