Problems solved by technology

A portion of the liquid fuel passes through this void and evaporates producing tar, which solidifies and closes the fuel injection hole, causing it to exhibit injection defects
Also, the fuel supply does not go smoothly, resulting in poor exhaust gas quality or engine shutdown

And a cone-shaped part can be formed on the lower end part of the tip penetrating part.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2010-0123555 filed in the Korean Intellectual Property Office on December 6, 2010, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to an LPI injector. More particularly, the present invention relates to an LPI injector that prevents LPG fuel from remaining between an injection portion and an injection pipe. Background technique [0004] In general, an LPI (Liquefied Petroleum Gas Injection) engine includes a fuel pump arranged in a fuel tank, in which LPG fuel is liquefied by its high pressure of 5 to 15 bar, and injectors inject the liquefied fuel into each cylinder of the engine so that the engine Running, this is a new technology (Mono fuel method). [0005] Since the LPI engine injects liquid fuel into the cylinder, components such as the carburetor and mixer...
