  • Patent number: 5660154
    Abstract: An improved intake manifold, for uniformly charging each cylinder of a multi-cylinder internal combustion engine. The manifold comprises a structure having bifurcated branches which define multiple through passageways, each passageway fluidly connecting the air inlet of the manifold to the intake valve chamber of one of the cylinders. For eight-cylinder engine, each through passageway encounters four fluid flow channels distinguishable by three bifurcations in the structure between the intake valve chamber at which the passageway terminates and the air inlet. The engine firing sequence dictates which through passageways share a fluid flow channel in common beyond each successive bifurcation in the structure.
