を特徴とする吸・排気ポート構造。 Each cylinder has a pair of intake valve holes and a pair of exhaust valve holes, and the pair of intake valve holes are arranged symmetrically with respect to the center of the cylinder, and the centers of the pair of intake valve holes are connected. In a multi-cylinder in-line four-stroke internal combustion engine, the pair of exhaust valve holes are arranged symmetrically with respect to the center of the cylinder on another straight line that passes through the center of the cylinder at right angles to the straight line. The two intake ports that communicate with the
The exhaust ports are extended apart from each other on both sides of the cylinder head, and the two exhaust ports extending from the exhaust valve holes of each cylinder are respectively merged into one exhaust port of another adjacent cylinder within the cylinder head, so that all of the engine's exhaust gas is An intake/exhaust port structure characterized by extending the ports to one side of the cylinder head.
