ンジンの吸気装置。[Claims for Utility Model Registration] Each cylinder has a first intake port and a second intake port that branch from the downstream side of the intake port opening of the cylinder head, which is provided with first and second intake valves and a spark plug. An intake port formed by forming a Siamese port, forming a partition between the first intake port and the intake port opening to provide a narrow passage and a wide passage, and disposing a swirl control valve in the wide passage. A partition wall formed in the first intake port is formed in the vertical direction of the cylinder head, and the downstream side of the partition wall is located near the first intake valve hole of the first intake valve, and the narrow passage The cross-sectional area is gradually reduced from the upstream side to the downstream side, and an injector is disposed near the valve hole of the first intake valve on the wide passage side of the first intake port, and the tip of the injector is disposed near the valve hole of the first intake valve. is exposed in the wide passage, and the injector directs the injection direction of the injector toward an opening between the first intake valve and the valve seat when the first intake valve is fully open, and also toward the spark plug. An intake system for an engine, wherein the fuel injection timing of the injector is set during the intake stroke of the engine.
