Intake manifold structure for a V-type internal combustion engine
This patent describes an intake manifold for a V-type internal combustion engine with two cylinder banks and cylinder inlet ports. This manifold consists of an air inlet opening, two supply tubes connected to the inlet opening, the supply tubes arranged substantially in the shape of a ''U''. Each supply tube is mounted substantially above and paralle to one cylinder bank, branch tubes form longitudinally along each supply tube and extending across the engine with an open end extending substantially perpendicular to the supply tubes. The branch tubes are arranged such that at least two of the branch tubes extending from the same supply tube are vertically aligned one on top of the other at the supply tube along a plane normal to the supply tube, and for a portion of their lengths extending from that supply tube. Connectors connect each branch tube open end to a cylinder inlet port on an opposite side of the engine from the supply tube to which that branch tube is connected.
