CONDENSATION-AND-ICING FREE NOZZLE FOR LIQUID-PHASE FUEL INJECTION SYSTEM

摘要

According to the present invention, a liquid fuel injection nozzle (1000) for preventing dew condensation and freezing is configured to comprise a first nozzle tube (100) formed with a transport path (110) through which LPG is transported; a second nozzle pipe (200) surrounding the outer peripheral surface of a first nozzle pipe (100); and a polished surface (300) formed by polishing the surface of the second nozzle pipe (200) at a low surface illumination than the surface illumination by a machining process in order to grow dew condensation and freezing if a threshold radius of a concentrate generated in surface flaws of the second nozzle pipe (200) increases, as the energy flows into the concentrate.
