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

摘要

A fuel system has a fuel injector (200) directly mounted with a fuel rail (300). The fuel rail (300) has a body with interior (311) and exterior (312) surfaces. The interior surface (311) defines a volume. The exterior surface (312) surrounds the interior surface (311). An aperture (314) extends between the interior (311) and exterior (312) surfaces in fluid communication with the volume. The fuel injector (200) has an inlet tube (210) with an inside surface (211) that defines a flow path through a portion of the fuel injector (200), and an outside surface (212) that surrounds the inside surface (211). The fuel injector (200) is disposed so that the flow path is in fluid communication with the volume. A rigid connection is disposed between at least one of the interior (310) and exterior (312) surfaces of the fuel rail (300) and the outside surface (212) of the inlet tube, the rigid connection securing and hermetically sealing the fuel rail (300) with the fuel injector (200).
