BUSHING FOR PROTECTING ICING OF LIQUID PHASE LPG INJECTION CAR

摘要

A bushing for preventing icing from occurring in a vehicle employing a liquid phase LPG injection system is provided to effectively supply fuel without using an expensive nozzle tip used for liquid phase LPG injection. A bushing for preventing icing from occurring in a vehicle employing a liquid phase LPG injection system comprises a fuel nozzle tip(20) and a busing(10) made of metal. The fuel nozzle tip includes one end portion coupled to an injector and an opposite end portion inserted into an intake port(31) of an engine head(30) to inject the fuel. The busing is tightly fitted to an outer peripheral edge of the other end portion of the fuel nozzle tip to obtain an air-tightness between the bushing and the outer peripheral edge. The busing prevents the fuel supply from being blocked by an icing formed at the circumference of the fuel nozzle tip. The icing is generated when the remaining fuel of a liquid phase is vaporized by absorbing ambient heat.
