Intake manifold with injectors and captive fuel rail

摘要

An intake manifold (10) includes a lower manifold assembly (12) that includes fuel injectors (16), an electrical conductor assembly (18) for the fuel injectors (16), and a fuel rail (26) retained between the lower manifold (12) and an upper manifold (14). The lower manifold (12) defines a portion of the air passage (30) to the engine and provides for a desired positioning of the injector nozzle (32) within the air passage (30). The fuel injector (16) is sealed at a lower portion near the air passage (30) by being integrated into the lower manifold (12). A support segment (38) on the lower manifold (12) supports the fuel rail (26) over the fuel injectors (16). The upper manifold (14) includes a retention segment (34) that holds the fuel rail (26) against the lower manifold (12) and on the fuel injectors (16). <IMAGE>
