摘要

PURPOSE: A venturi structure of a mixer for an LPG engine is provided to improve the engine output by mixing the air introduced through a venturi with a fuel(LPG) supplied to the rear end of the venturi. CONSTITUTION: A venturi structure of a mixer for an LPG engine is composed of an air intake pipe, a venturi(2) for allowing the air introduced into the venturi to be fast by reducing the diameter of an air path, an injector installed at the outer side of the venturi(2) for injecting the fuel, and a fuel supply hole formed at the lower end of the venturi. The fuel injected from the injector is provided to the engine with the air passing through the venturi(2). A plurality of spiral grooves(10) are formed to swirl the air passing through the top of the venturi(2).
