FUEL SYSTEM INCLUDING A FUEL INJECTOR INTERNALLY MOUNTED TO A FUEL RAIL

WIPO Patent Application WO2002029241

A3

A fuel system has a fuel injector (200) directly mounted with a fuel rail (300). The fuel rail (300) includes a first portion (310-1) and a second portion (310-2) that form a body. The body has an interior surface (311) defining a volume, an exterior surface (312) surrounding the interior surface, and at least one aperture (314) disposed between the interior (311) and exterior (312) surfaces in fluid communication with the volume. The at least one fuel injector (200) has an inlet tube (210) with an inside surface (211) defining a flow path through a portion of the fuel injector (200) and an outside surface (212) surrounding the inside surface (211). The fuel injector (200) is disposed such that the flow path is in fluid communication with the volume. A rigid connection is disposed between the interior surface (311) of the fuel rail and at least one of the outside surface (212) and the inside surface (211) of the inlet tube (210). The rigid connection secures and hermetically seals the fuel rail (300) with the at least one fuel injector (200).
