Abstract
A variable intake passage is made of a tubular space that is formed with a fixed member and a movable member arranged to face the fixed member and having a relative position with the fixed member changed. The movable member is moved to increase or decrease a distance of an air introducing portion from the combustion chamber to thereby change a passage length. The variable intake passage has a cross section that gradually increases from an upstream side to a downstream side in the air introducing direction. When the passage length of the variable intake passage is changed, the cross section of the air introducing portion of the variable intake passage is changed correspondingly.
