ド。 A chamber extending in the direction of the cylinder row and an intake port in each cylinder are connected by an independent branch intake pipe for each cylinder, and each branch intake pipe is formed into a substantially L-shape when viewed from the side. On the other hand, the cross-sectional shape of each of the branched intake pipes is approximately elliptical, with the longer diameter in the direction perpendicular to the cylinder row at the connection to the chamber, and the longer diameter in the direction of the cylinder row at the connection to the intake port. In the intake manifold formed in an oval shape, the cross-sectional shape at the curved portion of each of the branched intake pipes is approximately oval with the long axis in the direction of the cylinder row, or approximately rectangular with the long side in the direction of the cylinder row. Between this curved part and the connecting part to the chamber, a substantially oval shape with the long axis in the direction perpendicular to the cylinder row, or a substantially oval shape with the long axis in the direction of the cylinder row, or a long side in the direction of the cylinder row. An intake manifold for an internal combustion engine, characterized in that the intake manifold is configured to change into a substantially rectangular shape.
