Abstract
A fuel injector for an engine includes a connection to a fuel source, a nozzle which provides an outlet from the fuel injector, a fuel path from the fuel source to the nozzle, a valve between the fuel path and the nozzle, and a gas injection mechanism configured to insert a gas core into the fuel.
Claims43
A fuel injector for an engine, comprising:
- a connection configured to receive fuel from a fuel source;
- a nozzle configured to provide an outlet for the fuel from the fuel injector;
- a fuel path extending from the fuel source to the nozzle;
- a valve between the fuel source and the nozzle configured to selectively block the flow of fuel within the fuel path;
- and
- a gas injection mechanism configured to inject a gas core into the fuel at a location along the fuel path.

A fuel injector for an engine, comprising:
- a connection configured to receive fuel from a fuel source;
- a nozzle configured to provide an outlet for the fuel from the fuel injector;
- a fuel path extending from the fuel source to the nozzle;
- a valve stem shaped to engage a valve seat to control the flow of fuel through the fuel path;
- and
- an annulus within the valve stem and coupled to a gas source;
- wherein the annulus is configured to provide gas to a core of a fuel stream of the fuel, in the fuel path, flowing around the valve stem,
- wherein the valve stem is coupled to a solenoid configured to position the valve stem relative to the valve seat.
