FUEL COOLED INJECTOR TIP |
| 摘要 |
A fuel injector is provided comprising an outer housing, a nozzle housing disposed within the outer housing, a flow path between the outer housing and the nozzle housing, the flow path being coupled to a low pressure fuel source, and a circumferential gap in flow communication with the flow path and extending about a tip of the fuel injector between an outer surface of the nozzle housing and an inner surface of a combustion shield adjacent the injector tip. The circumferential gap is in flow communication with a drain gap between the outer housing and a bore for receiving the fuel injector, the drain gap routing the low pressure fuel away from the injector tip. |

1. A fuel injector, comprising:
an outer housing; a nozzle housing disposed within the outer housing; a flow path between the outer housing and the nozzle housing, the flow path being coupled to a low pressure fuel source; and a circumferential gap in flow communication with the flow path and extending about a tip of the fuel injector between an outer surface of the nozzle housing and an inner surface of a combustion shield adjacent the injector tip; wherein the circumferential gap is in flow communication with a drain gap between the outer housing and a bore for receiving the fuel injector, the drain gap routing the low pressure fuel away from the injector tip. |
