INJECTOR WITH NEEDLE WAVERING PREVENTION STRUCTURE

摘要

Disclosed herein is a side feeding type LPI injector including a fuel injection chamber in which fuel is injected into a combustion chamber of an engine through a fuel inlet, and a fuel supply passage through which fuel is injected into the fuel injection chamber in a direction transverse an injection direction of the fuel inlet. The fuel supply passage consists of at least three fuel supply passages which are circumferentially formed at equal intervals. Thus, it is possible to prevent fuel from leaking and improving durability of components by reducing the wavering of a needle, and of increasing combustion efficiency through swirl.
