International Classification:

B05B 130

US Classification:

2395851, 2395853, 2395855, 2511291

Abstract:

A dual-coil outwardly-opening fuel injector including a fuel tube connected at a lower end to a lower injector housing. Within the fuel tube are a lower (opening) solenoid pole piece, a specially-formed armature, and an upper (closing) solenoid pole piece. A seat assembly including an injector nozzle, swirler, and valve seat are adjustably threaded into the lower housing. A pintle assembly, including a solid pintle portion supporting a valve head and a tubular portion welded thereto, is axially disposed within the fuel tube and is welded to the armature which is spaced from the lower pole piece by a distance equal to the opening stroke of the valve. A return spring adjustment mechanism disposed on the upper pole piece engages the upper end of the pintle assembly for varying the closing force of the return spring. Opening and closing solenoid preassemblies are mounted external to the fuel tube for magnetically engaging the pole pieces and armature within in known fashion.

International Classification:

F02M061/00

US Classification:

23953312, 239596, 239463

Abstract:

A fuel swirler plate for improving atomization of fuel in a fuel injector. A plurality of identical fuel supply passages is formed in the plate, each passage including an outer fuel reservoir region; a region having converging walls wherein fuel is accelerated and turned partially tangential to the axis of the plate and fuel injector; a metering region wherein flow is regulated; and an exit region wherein the fuel is combined with similar fuel flows from the other passages to form a high velocity swirl annulus between the swirler plate and a pintle ball of the fuel injector. An advantage of the novel swirl plate over prior art plates is that, when the injector valve is closed, only a very small volume of fuel resides in the swirl annulus between the pintle ball and the exit region of the plate, and such residual fuel is urged rotationally and becomes the leading edge of a new vortex the next time the valve is opened, thus minimizing SAC spray formation. The present invention is useful in fuel cells, burners, and in both direct injection and port injection fuel injectors of internal combustion engines.

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

H01R 9/24

US Classification:

439884, 439888

Abstract:

An electrical connector for use in forming a wire-wrapped welded terminal connection. The connector is formed by stamping and folding from a sheet of metal stock to include an integral sleeve element attached by a strap. During assembly of the connection prior to welding, the terminal is wrapped with wire as in the prior art and then the strap is folded to position the integral sleeve element correctly about the wrappings to form a weldable assembly functionally identical with the prior art sleeved assembly. Because the sleeve element is formed integrally with the connector and attached by a foldable strap, the element is automatically positioned correctly and is held in place by the strap during welding.

International Classification:

B05B001/30

US Classification:

239/533200

Abstract:

An outwardly-opening fuel injector including a conical valve seat and conical valve head having nominally identical cone angles and mating lengths along the conical frustum between about 0.25 mm and about 0.30 mm. One of either the seat surface or the head surface is provided with an annular undercut to limit the length of mating contact to the desired range. The mating lengths and seal areas remain constant with use because the undercut prevents further changes in mating length. The resulting seal area prevents recession of the head into the seat with use, and therefore the valve stroke is predictable and constant. Further, the undercut provides a sharp corner in the fuel flow path downstream of the seal area, which increases the turbulent kinetic energy of fuel being discharged as a spray cone.

International Classification:

F02M 5100

US Classification:

123456

Abstract:

A fuel system for use on an internal combustion engine has a fuel metering body which defines a fuel plenum therein. The plenum has an inlet for pressurized fuel, a pressure regulator, and a fuel outlet. Disposed within the fuel plenum, in fluid communication with one another, the inlet and the outlet, are a plurality of fuel injectors. The fuel injectors have outlets which extend through the fuel meter body and deliver fuel to the intake ports of the associated engine through flexible fuel lines terminated by pressure pulse activated poppet nozzles providing a significant degree of application flexibility. The fuel meter body mounts within the intake manifold such that fuel and electrical connections extend out of the manifold for simplified source attachment.

International Classification:

H01H 4732

US Classification:

361156

Abstract:

Inductive energy from the coil of an electromagnetic actuator is stored in capacitive network at a relatively high voltage when the actuator is deenergized. When the actuator is energized, the capacitive network is coupled to the coil thereby releasing the stored energy at a high voltage to the coil.

International Classification:

F02M 4700
B05B 130

US Classification:

2395851

Abstract:

A direct injection fuel injector and method of operation wherein high fuel pressure exerting an opening force on an injection valve is slightly overbalanced by a return spring tending to close the valve. A first solenoid acts to open the valve against the excess return spring force and a second solenoid acts to close the valve when the first solenoid is de-energized. Rapid valve closing is provided by energizing the second solenoid before de-energizing the first solenoid, the force of the second solenoid when the valve is open being insufficient to overcome the force of the first solenoid holding the valve open. Thus, the second solenoid magnetic force is fully developed and quickly closes the injection valve when the first solenoid is de-energized. Various additional features are disclosed.
