Abstract
A fuel system has a fuel injector directly mounted with a fuel rail. The fuel rail includes a first portion and a second portion that form a body. The body has an interior surface defining a volume, an exterior surface surrounding the interior surface, and at least one aperture disposed between the interior and exterior surfaces in fluid communication with the volume. The at least one fuel injector has an inlet tube with an inside surface defining a flow path through a portion of the fuel injector and an outside surface surrounding the inside surface. The fuel injector is disposed such that the flow path is in fluid communication with the volume. A rigid connection is disposed between the interior surface of the fuel rail and at least one of the outside surface and the inside surface of the inlet tube. The rigid connection secures and hermetically seals the fuel rail with the at least one fuel injector.
