置。The intake port, which is opened and closed by the intake valve, is divided into upper and lower parts by a partition wall, with the upper part serving as a high-load intake port and the lower part serving as a low-load intake port. In an engine in which a low-load intake port is formed to face downward along the cylinder center axis, and the low-load intake port is formed so that its axis is substantially parallel to the lower end surface of the cylinder head and offset from the cylinder center axis. An intake system for an engine, characterized in that the downstream end of the partition wall protrudes into a high-load intake port by a set amount.
