徴とするエンジンの吸気装置。A low-load intake port that supplies intake air during low engine load and high engine load, and a high-load intake port that supplies intake air during high engine load are established in the combustion chamber, respectively. In an engine intake system in which a low-load intake valve and a high-load intake valve are provided, and the operation of the high-load intake valve is stopped at low load, the downstream side of the intake passage is connected to the low-load intake valve. It branches into a low-load intake passage that connects to the intake port and a high-load intake passage that connects to the high-load intake port, and a fuel supply device that supplies fuel to the intake passage is installed upstream of the branch. However, the shape of the connection between the intake passage upstream of the branch, the low-load intake passage, and the high-load intake passage is such that the wall-flow fuel flowing down along the inner wall of the intake passage is more concentrated in the high-load intake passage than in the low-load intake passage. An intake system for an engine, characterized in that a communication path is formed so that a large amount of air flows through the air, and communicates a high-load intake port immediately upstream of the high-load intake valve with the low-load intake port.
