Abstract
본 발명은 천연가스 차량의 연료 공급장치에 관한 것으로, 연료의 공급원인 원료 탱크(1)와, 상기 연료 탱크로부터 엔진에 이르도록 설치된 연료 공급 파이프(2)와, 상기 연료 공급 파이프를 흐르는 연료의 압력을 엔진에서 요구하는 적정의 압력으로 강하시키기 위한 레귤레이터(3)와, 상기 연료 공급 파이프의 단부에 설치된 연료 분배 파이프(5)와, 상기 연료 분배 파이프에 연결되어 공급되는 연료를 엔진의 실린더에 분사하는 수개의 인젝터(6)를 포함하는 천연가스 차량의 연료 공급장치에 있어서, 엔진의 시동이 꺼짐과 동시에 작동하여 상기 연료 분배 파이프로의 연료의 공급을 차단하는 수단(10)(10´), (11), (12)(12´), (13)을 구비하여 연료 분배 파이프에서의 연료의 누설을 방지 내지는 최소화 할 수 있도록 한 것이다. 이와 같은 본 발명에 의한 천연가스 차량의 연료 공급장치는, 엔진의 시동이 꺼짐과 동시에 연료 분배 파이프로의 연료의 공급이 차단되므로 연료 분배 파이프에서의 연료의 누설량을 최소화 할 수 있다. 따라서 종래와 같은 과다한 연료의 누설로 인한 폭발의 위험으로부터 벗어날 수 있으며, 또한 연료 소모의 저감으로 주행 거리의 증가가 가능하게 됨으로써 경제적인 주행을 이룰 수 있다.The present invention relates to a fuel supply device for a natural gas vehicle, comprising a raw material tank (1) for supplying fuel, a fuel supply pipe (2) installed to reach the engine from the fuel tank, A regulator (3) for lowering the pressure to a desired pressure required by the engine, a fuel distribution pipe (5) installed at the end of the fuel supply pipe, and a fuel supply device connected to the fuel distribution pipe (10, 10 ') for shutting off the supply of fuel to the fuel distribution pipe at the same time when the start of the engine is turned off, the fuel supply system comprising a plurality of injectors (6) , (11), (12), (12 '), (13) so as to prevent or minimize leakage of fuel in the fuel distribution pipe. The fuel supply device for a natural gas vehicle according to the present invention can minimize the leakage amount of fuel in the fuel distribution pipe because the supply of fuel to the fuel distribution pipe is blocked at the same time when the engine is turned off. Therefore, it is possible to escape from the risk of explosion due to the leakage of the excessive fuel as in the prior art, and the mileage can be increased by reducing fuel consumption, thereby achieving economical running.
