Patent
·
OSTI ID:7034031
This patent describes an intake port structure for an internal combustion engine having a cylinder head, the cylinder head has a first end adjacent a first cylinder, a second cylinder, and the opposite end adjacent a last cylinder. Each of the cylinders has a combustion chamber at least two intake valves provided for each cylinder. The cylinder head having two independent intake ports, and at least one siamese intake port comprising a common port, a second helical port and a first straight port; the second helical port is disposed in a tangential direction of the second cylinder and communicated with one of the intake valves of the second cylinder. The first straight port is disposed in a tangential direction of the first cylinder and communicated with one of the intake valves of the first cylinder. One of the independent intake ports has a first helical port and communicates with the other intake valve of the first cylinder having the first straight port, and the other independent intake port has a second straight port and communicates with one of the intake valves of the last cylinder.
