Abstract
An intake arrangement for an internal combustion engine, including an intake manifold including an intake collector and a plurality of branch pipes connected with the intake collector. The branch pipes extend in substantially same direction. The intake collector includes an inlet opening through which an intake air flow is introduced into the intake collector, and branch openings to which branch pipes are connected. The branch openings are arranged along a longitudinal direction of the intake collector such that as a distance thereof from the inlet opening decreases, an amount of offset thereof from a reference streamline of the intake air flow extending through substantially a center of the inlet opening along the longitudinal direction of the intake collector increases.
