Liquid phase injection tip icing prevention

摘要

A fuel injector assembly is provided herein. The fuel injector assembly includes an insulated delivery conduit in fluidic communication with a fuel pump and a conductive enclosure at least partially surrounding the insulated delivery conduit. The fuel injector assembly further includes a seal positioned between the insulated delivery conduit, conductive enclosure, and the fuel injector outlet with radial and axial forces against an exterior surface of the insulated delivery conduit, interior surface of the conductive enclosure, and the exterior surface of fuel injector outlet.

1. A fuel injector assembly comprising:
an insulated delivery conduit fluidically communicating with a fuel tank; a conductive enclosure at least partially surrounding the conduit; and a seal positioned adjacent to an inlet of the insulated delivery conduit and between the conduit, the conductive enclosure and a fuel injector outlet exerting axial and radial forces against an exterior surface of the conduit and an interior surface of the conductive enclosure and the fuel injector outlet, the seal tapering in a downstream direction and an upstream direction, and the seal extending in an axial upstream direction past the inlet of the insulated delivery conduit when uncompressed, and the seal not extending in the axial upstream direction past the inlet when compressed.
