Field of the Invention The present invention relates to a fuel evaporation gas control system of a vehicle. In particular, the present invention relates to an apparatus for minimizing the emission of fuel evaporation gas by improving a fuel supply device of a vehicle. It is possible to reduce production costs and production time, improve productivity and economics, and reduce environmental pollution by minimizing the emission of fuel evaporation gas. The present invention relates to an apparatus capable of producing a phosphorus vehicle and improving a commercial property of the vehicle.

일반적으로 차량의 연료공급장치는 크게 연료펌프를 구비한 연료탱크와 캐니스터로 이루어지며, 연료탱크는 연료펌프를 통하여 연료탱크 내에 저류된 액체의 연료를 펌핑하여 엔진으로 공급하게 된다.In general, the fuel supply device of a vehicle is composed of a fuel tank and a canister with a fuel pump, and the fuel tank pumps the fuel of the liquid stored in the fuel tank through the fuel pump to supply the engine.

또한, 캐니스터는 엔진이 정지되었을 때 기화기의 뜨개실과 연료탱크에서 증발하는 연료가스를 포집하여, 대기 중으로 방출되는 것을 방지하기 위하여 설치해 높은 활성탄을 넣은 관을 지칭하며, 이와 같이 캐니스터에 포집된 연료는 엔진 시동 시에 흡기다기관을 통하여 엔진으로 유입되어 연소가 이루어진다.In addition, the canister refers to a tube containing high activated carbon installed to capture the fuel gas evaporating from the knitting chamber and fuel tank of the carburetor when the engine is stopped and to prevent it from being released into the atmosphere. At engine start-up, combustion occurs by entering the engine through the intake manifold.

도 1은 종래의 차량의 연료공급장치를 도시하는 개략도이다.1 is a schematic diagram showing a fuel supply apparatus of a conventional vehicle.

도 1에 도시된 바와 같이 종래의 차량의 연료공급장치는, 연료주입구(11) 및 필러파이프(12)와 조인트튜브(13)를 구비하여 액체상태의 연료가 내부에 저류된 연료탱크(10)와; 상기 연료탱크(10) 내에 위치하여 액체상태의 연료를 연료필터(21)를 통하여 엔진으로 공급(40)하는 연료펌프(20)와; 상기 연료탱크(10) 내의 증발된 가스형태인 기체상태의 연료를 포집하여 서지탱크(50)를 통하여 엔진(40)에 공급하는 캐니스터(30)로 구성된다.As shown in FIG. 1, a conventional fuel supply apparatus of a vehicle includes a fuel inlet 11, a filler pipe 12, and a joint tube 13, in which a fuel in a liquid state is stored therein. Wow; A fuel pump 20 positioned in the fuel tank 10 for supplying a liquid fuel to the engine through a fuel filter 21; The canister 30 collects gaseous fuel in the form of evaporated gas in the fuel tank 10 and supplies it to the engine 40 through the surge tank 50.

상기와 같이 구성된 종래의 차량의 연료공급장치는 도 1에 도시된 바와 같이, 연료탱크(10)에 저류된 액상의 연료는 연료펌프(20)에 의하여 직접 엔진(40)으로 공급되며, 상기 연료펌프(20)와 엔진(40) 사이에 체결된 연료필터(21)가 연료를 걸러 주게되어 액체상태인 연료에 포함된 이물질을 제거하게 된다.In the conventional fuel supply apparatus of the vehicle configured as described above, as shown in FIG. 1, the liquid fuel stored in the fuel tank 10 is directly supplied to the engine 40 by the fuel pump 20. The fuel filter 21 coupled between the pump 20 and the engine 40 filters the fuel to remove foreign substances contained in the fuel in the liquid state.

또한, 상기 연료탱크(10)의 상부에 위치하는 증발가스 상태의 연료는 ORVR밸브(On-board Refueling Vapor Recovery Valve)(31)와 벤트밸브(32)를 통하여 캐니스터(30)와 서지탱크(50)를 거쳐 엔진으로 공급된다.In addition, the fuel in the boil-off gas state located in the upper portion of the fuel tank 10 is through the ORVR valve (On-board Refueling Vapor Recovery Valve) 31 and the vent valve 32 and the canister 30 and the surge tank 50 It is supplied to the engine via).

ORVR은 주유소에서 연료 주입 시에 연료탱크(10)내의 연료 증발가스나 주입과정에서 발생되는 증발가스의 유출을 방지하기 위해 증발가스를 캐니스터(30)에 포집시키고, 주행시는 엔진(40)으로 공급하여 연료증발가스가 연료주입구(11)를 통해 차량 밖으로 배출되지 않도록 규제하는 시스템이다.The ORVR collects the boil-off gas into the canister 30 to prevent the leakage of the fuel boil-off gas in the fuel tank 10 or the boil-off gas generated during the injection process at the filling station, and supplies the engine 40 to the engine 40 when driving.
