  • Publication number: 20040211394
    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.

  • Patent number: 6742504
    Abstract: A mechanical oscillator for attenuating pressure waves formed in a rail having a volume of fluid therein includes a rigid enclosed fluid cavity having a selected volume, the volume communicating with the rail actuating fluid though an orifice having a select volume for containing actuating fluid, the orifice having an aperture in fluid communication with the actuating fluid selected such that when an pressure wave impinges on the aperture of the orifice, the motion of the actuating fluid in the volume of the orifice is set to vibrating, the vibrating acting to excite the actuating fluid within the enclosed volume, a resulting amplified motion of the actuating fluid in the orifice, due to phase cancellation between the actuating fluid in the volume of the orifice and the actuating fluid volume in the enclosed cavity, causing energy absorption of the pressure wave due to frictional drag in and around the orifice. An pressure wave attenuator and a method of attenuation are also included.
