Abstract
Nozzles and method of making the same are disclosed. The disclosed nozzles have a non-coined three-dimensional inlet face and an outlet face opposite the inlet face. The nozzles may have one or more nozzle through-holes extending from the inlet face to the outlet face. Fuel injectors containing the nozzle are also disclosed. Methods of making and using nozzles and fuel injectors are further disclosed.
Claims20
A fuel injector nozzle comprising:
- an inlet face;
- an outlet face opposite said inlet face;
- and
- nozzle through-holes, with each nozzle through-hole comprising at least one inlet opening on said inlet face connected to at least one outlet opening on said outlet face by a cavity defined by an interior surface, said inlet opening being larger than said outlet opening, and fuel flowing out of said outlet opening is directed at an acute or obtuse angle from said outlet face and toward at least one target location a desired distance from said outlet face,
- wherein fuel flowing out of a plurality of said through-holes form fuel streams that focus to a single target location a desired distance from said outlet face.
A method of reducing a SAC volume of a fuel injection system of a vehicle, said method comprising incorporating a nozzle into the fuel injection system, wherein one or more inlet face features of the nozzle extend into a ball valve outlet region of a fuel injector system so as to reduce the SAC volume.
