LPLI ENGINE SYSTEM AND FUEL SUPPLYING METHOD THEREOF

摘要

An LPLI engine system is provided to reduce emission of unburned hydrocarbon and prevent the leakage of fuel leaking into an injector in the case of cold start. An LPLI(Liquefied Petroleum Gas Injection) engine system comprises an engine(100) generating kinetic energy by burning fuel; an injector(150) injecting LPG fuel, installed on the suction system of the engine; a fuel bombe(210) storing LPG fuel feeding into the injector; a feeding part(230) consisting of a supply line(231) feeding LPG fuel by connecting the injector a pressure regulator(300), installed on the feeding part, supplying fuel to the injector with a controller controlling the operation pressure of the pressure adjuster.
