ABSTRACT:
An intake arrangement for an internal combustion engine, including an intake manifold including an intake collector disposed above the engine body, a plurality of branch pipes extending from the intake collector to an intake side of the engine body over above the engine body in a curved state, and a connecting wall disposed between the branch pipes. The branch pipes extend in a direction substantially perpendicular to a longitudinal direction of the intake collector and are arranged with space between adjacent ones of the branch pipes. The connecting wall covers the space between the adjacent ones of the branch pipes and coextends with the branch pipes. The connecting wall has an outside air introducing opening opposed to the intake side of the engine body.
