FREEZING PREVENTION FOR INJECTION OF PROTRUDING ADIABATIC PIPE NOZZLE

摘要

The present invention relates to a spraying nozzle where an insulation pipe is protruding for preventing the freezing of an injector. More particularly, the spraying nozzle prevents freezing by outer air having high heat energy and kinetic energy by a thin insulation pipe protruding at a certain interval to the outside of a hot air flue; increasing the efficiency of an engine by reducing an area where ice is generated at the end surface of the insulation pipe such that the ice can be easily removed by the flow of outer air; and minimizing the damage to a fuel supplying part and the defects of engine operation due to the shortage of fuel supply caused by the freezing of an existing hot air flue.
