A method of reducing the force required to insert an elastomeric seal in a cavity of a metallic member includes tumbling the member in a tumbling machine with media to decrease the surface roughness of the member. Preferably, the tumbling step includes decreasing the surface roughness of the metallic member at least a portion of the member defining an entrance to the cavity. The method is particularly useful for reducing the force required to insert fuel injectors having top O-rings into fuel rail cups.

Method and apparatus for reducing the force required to insert a seal in a cavity

A a clip for mounting an elongated fuel rail with respect to an internal combustion engine. The fuel rail extends along a longitudinal axis and includes a mounting portion at an intermediate positon along the longitudinal axis, and the internal combustion engine includes a recess. The clip comprises a first portion adapted to engage the fuel rail, and a second portion adapted to be slidably received in the recess along a generally transverse axis with respect to the longitudinal axis. The first portion partially surrounds the longitudinal axis and is adapted to engage the mounting portion so as to prevent relative displacement along the longitudinal axis. The second portion is adapted to be releasably retained with respect to the recess.

Fuel rail mounting clip

A fuel system has a fuel injector directly mounted with a fuel rail. The fuel rail has a body with interior and exterior surfaces. The interior surface defines a volume. The exterior surface surrounds the interior surface. An aperture extends between the interior and exterior surfaces in fluid communication with the volume. The fuel injector has an inlet tube with an inside surface that defines a flow path through a portion of the fuel injector, and an outside surface that surrounds the inside surface. The fuel injector 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 and exterior surfaces of the fuel rail and the outside surface of the inlet tube, the rigid connection securing and hermetically sealing the fuel rail with the fuel injector.

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.

Fuel system including a fuel injector internally mounted to a fuel rail

The present invention provides an assembly having a fuel injector and a fuel supply device. The fuel injector has a first and second end, a fuel metering portion with a longitudinal axis extending therethrough, an outer shell surrounding the fuel metering portion and at least one fixing member that extends generally radially from the outer shell. The fixing member has a leg, where a portion of the leg is substantially parallel to the longitudinal axis. A cross member is located transverse to the portion of the leg and has a projection that has a substantially planar surface and extends toward the outer shell. The fuel supply device has a cup with an injector receiving opening and at least one connecting member with a mating surface adapted to engage the substantially planar surface of the fixing member. A method of connecting the fuel cup to the fuel injector and a method of disengaging the fuel cup from the fuel injector is also provided.

Clip for injector to fuel supply assembly

An integrated fuel rail portion and mounting bracket assembly is provided. The assembly includes an elongated support portion and at least one mounting bracket integrally connected to the elongated support portion. A method of forming the assembly is also provided.

Stamped fuel rail with integrated mounting brackets

The present invention provides an assembly having a fuel injector and a fuel supply device. The fuel injector has first and second ends, a fuel metering portion, having a longitudinal axis extending therethrough, an outer shell surrounding the fuel metering portion, and at least one fixing member extending radially from the outer shell proximate the first end. The fixing member has first and second longitudinal legs extending to a first transverse leg, where all of the legs form a void. Each longitudinal leg has a first portion extending from the outer shell and a second portion that is substantially parallel to the longitudinal axis. The first transverse leg has a substantially planar surface. The fuel supply device has a cup with an injector receiving opening and at least one tab, extending generally radially from the cup. The first end of the fuel injector is disposed in the injector receiving opening. The at least one tab is adapted to releasably engage the fixing member and has a configuration that corresponds with the configuration of the void.

Clip for attachment of fuel supply assembly

A fuel rail for a fuel injection system is disclosed. The fuel rail includes a first portion including a generally elongated base, at least one mounting bracket and a plurality of fuel cup openings in the generally elongated base. The fuel rail also comprises a second, generally U-shaped, portion having a first and second opposing sides. Each of the first and second opposing sides are sealingly connected to the generally elongated base with a laser weld. The second portion also has a supply end having a fuel supply opening, and a closed end, distal from the supply end. The closed end and the supply end are sealingly connected to the generally elongated base with a laser weld. A method of manufacturing the fuel rail is also disclosed.

Laser welded fuel rail and process of making same

A clip for mounting a fuel rail to an internal combustion engine is disclosed. The fuel rail has an outer surface and a projection on the outer surface. The engine has a retaining feature. The clip includes a body extending in a plane and first, second, and third pairs of rail legs extending from the body generally perpendicular to the plane. The second pair of rail legs is generally aligned with and disposed from a respective one of the first pair of rail legs by a predetermined distance. The third pair of rail legs is located distal from the first and second pairs of rail legs. Each of the third pair of rail legs is generally aligned with a respective one of the first pair of rail legs. A free end of each of the pairs of rail legs includes a generally concave surface juxtaposed from and biased toward the other leg of each of the first, second, and third pairs of rail legs. The clip further includes a pair of mounting legs extending from the body generally perpendicular to the plane. Each concave surface of the mounting legs are mountable to the outer surface of the fuel rail. The projection on the outer surface of the fuel rail is locatable between the first and second pair of rail legs. The mounting legs are insertable into the retaining feature such that the clip limits transverse and axial movement of the fuel rail relative to the internal combustion engine.
