Zusammenfassung: | A fuel injector concurrently injects a liquid fuel and a gaseous fuel into a combustion chamber of an internal combustion engine. An interior wall of an injector body defines a control chamber and an injection chamber. A needle valve is disposed within the body and has a control surface fluidly communicating with the control chamber. A liquid fuel inlet fluidly communicates with the control chamber and a gaseous fuel inlet fluidly communicates with the injection chamber. A delivery passage is defined by at least one of the needle valve and the interior wall and configured to place the control chamber in fluid communication with the injection chamber to permit flow of liquid fuel therebetween. |
