Abstract

본 발명은 다중기체연료분사식 차량엔진의 연료공급장치에 관한 것으로, 연료레일 전단의 연료공급라인상 일정위치에 고압의 연료가스를 인젝터 공급압력으로 감압시켜 주는 압력조절기를 설치하고, 상기 압력조절기에서 대칭으로 분기시킨 연료공급라인의 일단은 상기 연료레일의 일측단에, 타단은 상기 연료레일의 타측단에 각각 연결하여 연료가스가 상기 연료레일의 길이방향으로 양측에서 균일하게 유입될 수 있도록 구성함으로써, 전체적인 출력이 증대되고 엔진의 연소안정성이 향상되는 한편, 별도의 리턴라인을 설치할 필요가 없도록 한 것이다.The present invention relates to a fuel supply device for a multi-gas fuel injection vehicle engine, comprising: a pressure regulator for reducing a high pressure fuel gas to an injector supply pressure at a predetermined position on a fuel supply line in front of a fuel rail; One end of the symmetrically branched fuel supply line is connected to one end of the fuel rail and the other end to the other end of the fuel rail, so that fuel gas can be uniformly introduced from both sides in the longitudinal direction of the fuel rail. This increases the overall power output and improves the combustion stability of the engine, while eliminating the need for a separate return line.
