Abstract
An engine includes a cylinder head, an intake manifold, and a partition wall. The cylinder head includes an intake port communicating with a combustion chamber. The intake manifold is fixed to the cylinder head and includes an intake passage communicating with the intake port. The partition wall that separates at least part of the intake port into a first channel and a second channel. The partition wall includes a partition wall member extending from the intake port to the intake passage and fixed to an inner wall of the intake port and an inner wall of the intake passage.
Claims11
An engine, comprising:
- a cylinder head comprising an intake port communicating with a combustion chamber;
- an intake manifold fixed to the cylinder head and comprising an intake passage communicating with the intake port;
- a partition wall separating at least a part of the intake port into a first channel and a second channel, the partition wall comprising a partition wall member extending in an extending direction from the intake port to the intake passage and fixed to an inner wall of the intake port and an inner wall of the intake passage;
- a first opposing pair of grooves formed on an inner surface of the intake port and extending along the extending direction;
- and
- a second opposing pair of grooves formed on an inner surface of the intake passage and extending along the extending direction,
- wherein, in an orthogonal direction to the extending direction, a width of the partition wall member is equal to or more than a width of the intake passage, and
- wherein the partition wall member fits into the first opposing pair of grooves and the second opposing pair of grooves at both ends in the orthogonal direction.
An engine, comprising:
- a cylinder head comprising an intake port;
- an intake manifold attached to the cylinder head and comprising an intake passage communicating with the intake port;
- and
- a partition wall separating at least a part of the intake port into a first channel and a second channel, the partition wall comprising a partition wall member extending in an extending direction from the intake port to the intake passage;
- a first opposing pair of grooves formed on an inner surface of the intake port and extending along the extending direction;
- and
- a second opposing pair of grooves formed on an inner surface of the intake passage and extending along the extending direction,
- wherein, in a width direction orthogonal to the extending direction, an end portion of the partition wall member fits into the first opposing pair of grooves and the second opposing pair of grooves.
An engine, comprising:
- a cylinder head comprising an intake port, the intake port extending in a first direction;
- an intake manifold attached to the cylinder head and comprising an intake passage communicating with the intake port, the intake passage extending in a second direction;
- a first opposing pair of grooves formed on an inner surface of the intake port and extending along the extending direction;
- a second opposing pair of grooves formed on an inner surface of the intake passage and extending along the extending direction;
- and
- a partition wall member including a first plate portion located in the intake passage and a second plate portion located in the intake port, the first plate portion extending along the first direction, the second plate portion being integrally formed with the first plate portion and extending along the second direction,
- wherein the first plate portion fits into the first opposing pair of grooves and the second plate portion fits into the second opposing pair of grooves.
