Title:
FUEL RETURN PASSAGE FOR AN INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO2004097204
Kind Code:
A3
Abstract:
An apparatus for and method of returning surplus fuel from a fuel injector (103) utilizes an internal channel (108) of the fuel injector (103) and a fuel return passage in a cylinder head (101) of an internal combustion engine (100). Each fuel injector (103) may be partially disposed in the fuel return passage (113), which may have openings (301) that are at least partially shaped to receive at least a part of the fuel injector (103). One or more ports (109) through which surplus fuel exits the fuel injector (103) are disposed adjacent to an optional groove (111) or adjacent to the openings (301) of the fuel return passage (113). External fuel return lines to each of the fuel injectors (103) are thus eliminated.
