Abstract
본 발명은 천연가스 차량의 연료 공급장치에 관한 것으로, 연료의 공급원인 연료 탱크(1)와, 상기 연료 탱크로부터 엔진에 이르도록 설치된 연료 공급 파이프(2)와, 상기 연료 공급 파이프를 흐르는 연료의 압력을 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(7) 및 흡기 매니폴드(8)를 포함하는 천연가스 차량의 연료 공급장치에 있어서, 엔진의 시동이 꺼짐과 동시에 작동하여 상기 연료 분배 파이프(5)내의 연료를 흡수하여 레귤레이터(3)로부터 연료 분배 파이프(5)까지의 라인 압력을 낮추는 감압수단(10)(11)(12)(13)을 구비하여 구성한 것이다. 이와 같은 본 발명은 엔진의 시동이 꺼짐과 동시에 감압수단이 작동하여 연료 분배 파이프내의 연료를 흡수하여 저장하므로, 레귤레이터로부터 연료 분배 파이프에 이르는 라인의 압력을 대기압 수준으로 낮출 수 있다. 또한 본 발명은 엔진의 시동이 다시 '온'되는 경우 감압수단에 임시 저장되어 있던 연료가 연료 분배 파이프로 공급되어 사용되므로 연료의 소모를 줄일 수 있고, 이와 같은 모든 연료의 사용으로 차량의 주행거리를 증가시킬 수 있다.The present invention relates to a fuel supply apparatus for a natural gas vehicle, comprising a fuel tank (1) serving as a fuel supply source, a fuel supply pipe (2) installed to reach the engine from the fuel tank, A fuel distribution pipe (5) provided at an end of the fuel supply pipe, and a plurality of fuel injection pipes connected to the fuel distribution pipe for injecting fuel supplied to a cylinder of the engine In the fuel supply system for a natural gas vehicle including an injector 7 and an intake manifold 8, the engine 1 is operated at the same time when the engine is turned off, so that the fuel in the fuel distribution pipe 5 is absorbed from the regulator 3 (10), (11), (12) and (13) for lowering the line pressure to the fuel distribution pipe (5). The present invention can lower the pressure of the line from the regulator to the fuel distribution pipe to the atmospheric pressure level because the decompression means operates and the fuel in the fuel distribution pipe is absorbed and stored at the same time the engine is turned off. Further, according to the present invention, since the fuel temporarily stored in the decompression means is supplied to the fuel distribution pipe when the engine is started again, the consumption of the fuel can be reduced. By using all of the fuel, Can be increased.
