Intake manifold with injectors and captive fuel rail

摘要

An intake manifold includes a lower manifold assembly that includes fuel injectors, an electrical conductor assembly for the fuel injectors, and a fuel rail retained between the lower manifold and an upper manifold. The lower manifold defines a portion of the air passage to the engine and provides for a desired positioning of the injector nozzle within the air passage. The fuel injector is sealed at a lower portion near the air passage by being integrated into the lower manifold. A support segment on the lower manifold supports the fuel rail over the fuel injectors. The upper manifold includes a retention segment that holds the fuel rail against the lower manifold and on the fuel injectors.
