ABSTRACT:
An intake device of an engine comprising an intake passage which is common to a first intake valve and a second intake valve. The intake passage is divided into a first straight passage and a second straight passage by a dividing wall which extends toward a point upstream of the intake passage from a position between the first intake valve and the second intake valve. A downwardly projecting separating wall is formed on the upper wall of the intake passage. The separating wall extends from a position upstream of the upstream end of the dividing wall toward a point upstream of the intake passage along the axis of the first straight passage. An intake control valve is arranged between the separating wall and the side wall of the intake passage, which is located on the second straight passage side.
