Abstract

본 발명은 자동차의 연료탱크에 공급되는 연료를 안내하는 인렛 파이프의 직경을 작게하여 그 주변에 설치되는 다른 부품의 실장능력을 높일 수 있는 동시에 연료탱크의 내부에서 발생되는 증발가스를 연료 주입구를 통해 대기중으로 방출시키지 않아 이것을 규제하는 지역에는 판매를 가능하게 할 수 있고, 증발가스를 재활용하여 연료소비량을 줄일 수 있으며, 이에 따른 대기오염을 방지할 수 있고, 차량운행중에 발생하는 연료의 요동에 의해 인렛파이프와 연료 주입구를 통해서 발생할 수 있는 누유를 방지할 수 있는 자동차의 연료주입장치를 제공하기 위하여 일측단에는 차체의 바깥쪽에 설치되어 있는 연료 주입구(30)가 설치되고 타측단은 연료탱크(31)의 액상부측에 연통하는 인렛 파이프(32)로 구성되어 있는 자동차의 연료주입장치에 있어서, 상기 연료탱크(31)의 액상부(31a)측에 연결되어 있는 인렛 파이프(32)의 타측단에 유중펌프(P)의 흡입측(IP)을 연결하고, 그 유중펌프(P)의 토출측(OP)은 상기 연료탱크(31)의 액상부(31a)측에 위치시켜 액상부(31a)측으로 토출되도록 하며, 자동차의 배터리(BT)로부터 상기 유중펌프(P)로 공급되는 구동전류를 단속하는 마이크로스위치(SW)를 상기 연료 주입구(30)의 내주면에 설치아혀 연료주입 건(35)이 삽입되면서 터치온되어 상기 유중펌프(P)가 가동되도록 하는 한편, 상기 연료탱크(31)의 기상부(31b)에 일측단이 연결되는 증발가스 포집파이프(40)의 타측단을 자동차의 퓨얼 인젝터(JT)에 연결되어 있는 캐니스터(45)에 연통되도록 설치하여 연료탱크(31)내에서 발생하는 증발가스(G)를 상기 캐니스터(45)로 흘러들도록 구성한 것이다.The present invention can reduce the diameter of the inlet pipe for guiding the fuel supplied to the fuel tank of the vehicle to increase the mounting capacity of the other parts installed around the fuel inlet through the fuel inlet It is possible to sell to areas that regulate it because it is not released to the atmosphere, reduce fuel consumption by recycling boil-off gas, prevent air pollution accordingly, and fluctuations of fuel generated during vehicle operation In order to provide a fuel injection device for a vehicle that can prevent leakage that may occur through the inlet pipe and the fuel inlet, a fuel inlet 30 is installed at one end of the vehicle body and the other end is a fuel tank 31. In the fuel injection device of an automobile composed of an inlet pipe 32 in communication with the liquid phase side of The suction side IP of the oil-in-water pump P is connected to the other end of the inlet pipe 32 connected to the liquid-phase portion 31a side of the fuel tank 31, and the discharge side of the oil-in-water pump P ( OP) is positioned at the liquid phase portion 31a side of the fuel tank 31 to be discharged to the liquid phase portion 31a side, and controls the driving current supplied from the battery BT of the vehicle to the oil-in-water pump P. The micro switch SW is installed on the inner circumferential surface of the fuel inlet 30 so that the fuel injection gun 35 is inserted and touched to operate the oil-in-water pump P, while the gas phase part of the fuel tank 31 is operated. Evaporation generated in the fuel tank 31 by installing the other end of the boil-off gas collection pipe 40 connected to one end of the 31b so as to communicate with the canister 45 connected to the fuel injector JT of the vehicle. The gas G is configured to flow into the canister 45.
