Title: Intake device of an internal combustion engine

Abstract

An intake device of an internal combustion engine is described which consists of: an intake port; a separating wall arranged in the intake port and dividing an interior of the intake port into a straight port and a helical-shaped port which has a helical portion having a helix terminating portion; a control valve arranged in the straight port; a projection formed on a side wall of the separating wall, which defines the straight port, at a position downstream of the control valve, the projection having a tip face directed upstream of the intake port; a bypass passage formed in the separating wall and having an inlet opening and an outlet opening which is open to the helix terminating portion, the inlet opening being formed on the tip face; and an actuator for actuating the control valve in response to an engine load to close the control valve when the engine load is lower than a predetermined load and to open the control valve when the engine load is higher than the predetermined load.
