FREEZING PREVENTION FOR INJECTION OF DIFFUSER TYPE NOZZLE

摘要

The present invention relates to a diffuser-type injection nozzle for preventing an injector from freezing and more specifically, to a diffuser-type injection nozzle for preventing an injector from freezing which is capable of increasing engine efficiency by preventing the occurrence of frost at the end of a thermal conductivity tube in which a penetration hole is exposed and minimizing the damage of a fuel supply device or the defective operation of the engine due to lack of fuel supply caused by the freezing of the existing thermal conductivity tube as a vaporization groove communicated with the penetration hole at the end of the conductivity tube is formed and the vaporization groove is formed in a shape expanded from the inside to the outside of the thermal conductivity tube so that LPG fuel transferred through the penetration hole is transferred from the vaporization groove to one side and vaporized. Furthermore, user convenience and efficiency are increased as the effective surface tension is generated at the part in which the vaporization groove and the penetration hole are mutually connected so that the dribbling of the LPG fuel is suppressed when the pumping of the LPG fuel is stopped.
