Filed:

Apr 7, 2008

Appl. No.:

12/080867

Inventors:

Wenbin Xu - Pittsford NY, US
Leonard L. Shebert - Pittsford NY, US
Jay K. Sofianek - Webster NY, US

International Classification:

F02D 1/00
F02M 69/54
G06F 19/00

US Classification:

123457, 701103, 701113, 701112

Abstract:

A flow sensing fuel system for multiple port fuel injection gasoline engines, gasoline direct injection engines, or common rail diesel engines include a flow monitoring device positioned in a fuel flow passage between a fuel pump and a fuel rail, a fuel pressure sensor in fluid communication with said fuel rail, and a controllable pressure regulator closing to a fuel tank. By integrating flow monitoring device, fuel pressure sensor, and controllable pressure regulator in existing fuel systems, a flow sensing fuel system is provided that protects the engine and limits the fuel leaking into the environment in case of a stuck open condition or sealing problem of one or more injectors or in case of a leak in the fuel rail assembly. The flow sensing fuel system enables monitoring the fuel flow during engine start-up, during engine operation, and after engine shut down.

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

F02M 3704

US Classification:

123470

Abstract:

A spring clip assembly for connecting a fuel injector to a fuel rail in an internal combustion engine comprises a substantially circular ring having a circumferential outer surface, to which are attached a first and a second plurality of elongate fingers. The first plurality of elongate fingers extends in a first direction parallel to the axis of the ring and includes connecting means for attaching the ring to a fuel injector. The second plurality of elongate fingers extends in a second, opposite axial direction and includes connecting means for attaching the ring to the fuel rail. The spring clip assembly further comprises spring means held proximate a surface of the ring by either the first plurality or the second plurality of elongate fingers. The spring means provides a compressive load between the fuel injector and the fuel rail. A fuel rail-injector assembly comprises a fuel rail, a plurality of fuel injectors, and a corresponding plurality of the just-described spring clip assemblies for connecting the injectors to the rail.

International Classification:

F02M051/00

US Classification:

239/585100

Abstract:

An engine fuel injector includes an internal fuel passage in which pressure waves can develop upon opening and closing of an injection valve. A fuel pressure damper is associated with the fuel passage and operates to vary the internal volume of the fuel passage in a manner to reduce the amplitude of pressure variations and pressure waves in the fuel passage. A variety of fuel pressure damper embodiments are disclosed.
