Vehicle fuel injection system

Claim 1

In a vehicle having an engine including a plurality of air-fuel intake cylinders, and a source of air and fuel mixture therefor, the improvement including a manifold comprised of a readily removable, unitary housing having spaced end walls and an interconnecting wall joining said end walls, an inlet means adapted to be connected to said air-fuel source comprising a conduit disposed in one of said end walls and having a free end extending into the interior of the housing and terminating short of the other end wall, a plurality of substantially equally spaced discharge openings disposed in the interconnecting wall thereof remote from the said other end wall, said openings being disposed in a generally common plane, and a discharge opening provided in said other end wall opposite the free end of said conduit whereby lighter particles of said air and fuel mixture emanating from the conduit will be directed upwardly to be discharged through said openings with the heavier particles of said air and fuel mixture being directed downwardly to be discharged through said discharge opening, means adapted to connect each of said openings to a respective one of said cylinders and conducting said air and fuel mixture thereto, said conducting means being made from non-heat conducting material whereby the housing is separated from said engine a distance to minimize heat exchange relationship therewith, and recirculating means adapted to connect said discharge opening to said source of air and fuel for recirculating said heavier particles.
