Abstract
An engine, fuel injector, and method are disclosed. The method may include aligning an exhaust gas passage with an exhaust gas source to allow exhaust gas to enter a pre-chamber for a first duration; aligning a fuel passage with a fuel source to allow fuel to enter the pre-chamber for a second duration; and aligning injector nozzle connectors with injector nozzles, for a third duration, to allow a mixture of the fuel and the exhaust gas to be injected from the pre-chamber to the combustion chamber.
Claims17
A method of injecting fuel into a combustion chamber of an engine comprising:
- rotating an inner element relative to an injector body a first rotational amount and aligning an exhaust gas nozzle with an exhaust gas passage and an exhaust gas source to allow exhaust gas to enter a pre-chamber for a first duration;
- rotating the inner element relative to the injector body a second rotational amount and aligning a fuel nozzle with a fuel passage and a fuel source to allow fuel to enter the pre-chamber for a second duration;
- and
- rotating the inner element relative to the injector body a third rotational amount and aligning injector nozzle connectors with injector nozzles for a third duration to allow a mixture of the fuel and the exhaust gas to be injected from the pre-chamber into the combustion chamber, the injector nozzle connectors extending radially through an outer wall of the inner element.

A method, comprising:
- rotating an inner fuel injector element relative to an injector body of a fuel injector a first amount and aligning an injector exhaust gas passage with an exhaust gas source via an exhaust gas nozzle radially extending through an outer wall of the inner fuel injector element;
- rotating the inner fuel injector element a second amount and aligning a fuel passage with a fuel source via a fuel nozzle radially extending through the outer wall of the inner fuel injector element;
- and
- rotating the inner fuel injector element a third amount and aligning injector nozzle connectors with injector nozzles to inject a fuel and exhaust gas mixture from a pre-chamber to a cylinder, the injector nozzle connectors radially extending through the outer wall of the inner fuel injector element.
