Abstract
An engine having a rotary valve arranged in the intake port. The valve shaft of the rotary valve is eccentrically arranged relative to the longitudinal axis of the intake port. A projecting wall projects downward from the upper wall of the intake port and surrounds the valve guide of the intake valve. The projecting wall has an air flow guide portion the thickness and width of which gradually decreases in the direction towards the rotary valve. The upstream end of the air flow guide portion is aligned with the valve plate of the rotary valve when the rotary valve is fully open.
