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.
Claims5
An intake apparatus of an internal combustion engine for supplying an air to a combustion chamber of the internal combustion engine, comprising:
- a variable intake passage having a passage length from an air introducing portion to said combustion chamber configured to be changeable, the variable intake passage being 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 said fixed member changed, the movable member being moved to make a position of said air introducing portion farther from or closer to said combustion chamber to increase or decrease the passage length, wherein
- said variable intake passage has a cross section that gradually increases from an upstream side to a downstream side in an air introducing direction.
