  • Process for producing an intake manifold
    Patent number: 4887557
    Abstract: A process for producing an intake manifold having a main pipe made of wrought aluminum material and having an open end, a closed end opposite to the open end, a plurality of holes formed in its peripheral wall and outward tubular projections integral with the peripheral wall and each formed around each of the holes, and a plurality of branch pipes made of wrought aluminum material and each having one end fitting in and joined to each of the tubular projections. The manifold is smooth-surfaced in its interior, diminished in resistance to air and improved in air intake efficiency. The manifold requires no finishing procedure unlike those prepared by casting.
    Type: Grant
