| 主权项 | 1. A fuel injector for liquid phase injection of liquefied gaseous fuels for combustion chambers of an internal combustion engine, the fuel injector comprising a nozzle portion having an end from which gaseous fuel can be delivered through an outlet, the end of the nozzle portion being configured by the disposition of the outlet protruding up to 1.5 mm beyond a surface at the end of the nozzle portion surrounding the outlet wherein the surrounding surface is defined by a formation at the end of the nozzle portion, wherein the formation comprises a recess in the end of the nozzle portion about the outlet, and whereby the end of the nozzle portion is hotter than the recess and the resulting temperature gradient prevents or at least inhibits formation of ice on the end of the nozzle portion upon delivery of gaseous fuel through the outlet. | ||
