Abstract

저공해 연료인 천연가스(Compressed Natural Gas)를 가솔린 분사와 동시에 분사시킴으로써 연료의 미립화를 추구하여 기관의 출력을 증대시킴은 물론 배출되는 배기가스의 유해 성분을 저감시켜 배기가스의 강화규제를 만족시킬 수 있는 자동차용 연료 분사장치를 제공하는데 그 목적이 있다.Compressed natural gas, a low-polluting fuel, is injected simultaneously with gasoline injection to seek fuel atomization to increase engine output and to reduce harmful components of exhaust gases, thereby satisfying the regulations for strengthening exhaust gas. It is an object of the present invention to provide a fuel injector for a vehicle.

이에따라 딜리버리 파이프에 다수개의 연료인젝터가 장착되어 기관의 부하 상태에 따라 연료를 분사하는 MPI방식의 자동차용 연료 분사장치에 있어서, 상기한 연료 인젝터의 내측에 압축 천연가스를 저장하는 챔버가 마련되고 이 챔버와 연통됨은 물론 분사 구멍 위치까지 연장되어 니이들 밸브의 승강에 따라 출구가 선택적으로 개방되도록 분사 파이프가 배치되며, 상기한 연료 인젝터의 챔버와 각각 연통 설치됨은 물론 저공해 연료인 압축 천연가스가 저장된 저장 탱크와 소정의 일정 압력을 보전하도록 레귤레이터가 개재된 공급튜브가 연통 설치됨을 특징으로 한다.Accordingly, in the MPI-type vehicle fuel injector equipped with a plurality of fuel injectors in the delivery pipe and injecting fuel according to the load of the engine, a chamber for storing compressed natural gas is provided inside the fuel injector. The injection pipe is disposed so as to communicate with the chamber and extend to the injection hole position so that the outlet is selectively opened as the needle valve is lifted and lowered. It characterized in that the supply tank is interposed between the storage tank and the regulator is provided so as to maintain a predetermined predetermined pressure.
