Description
본 고안은 차량 연료탱크의 연료 증발가스 배출억제장치에 관한 것으로, 특히 연료 증발가스를 차콜캐니스터로 배출하기 위한 인너파이프가 연료탱크내에 설치되어 노면의 높은 온도로 인한 영향을 줄일 뿐만 아니라, 연료탱크를 차체에 밀착 취부시켜 연료탱크가 장착되어지는 차체부위의 형상을 단순화 시킬 수 있도록 된 차량 연료탱크의 연료 증발가스 배출억제장치에 관한 것이다.The present invention relates to a fuel evaporation gas emission suppression device of a vehicle fuel tank, in particular, an inner pipe for discharging the fuel evaporation gas to the charcoal canister is installed in the fuel tank to reduce the influence of high temperature on the road surface, as well as the fuel tank. And a fuel evaporation gas emission suppression apparatus of a vehicle fuel tank, which is capable of simplifying the shape of the vehicle body portion on which the fuel tank is mounted by attaching the gas tightly to the vehicle body.
일반적으로 연료탱크와 같이 연료계에서 발생되는 가솔린 증기는 탄화수소이기 때문에 대기를 오염시키므로 이것을 대기중으로 방출하지 않고 연소실로 유도하여 연소시키게 되는데, 이러한 장치인 연료 증발가스 배출억제장치는, 탱크내의 증발가스를 크랭크 케이스내에 저장하며 블로바이가스 환원장치를 이용해서 연소실로 인도하는 방식인 크랭크케이스 스토리지방식(Crank Case Storage System)과, 증발가스를 활성탄에 흡착시켜 저장하였다가 외기와 함께 기화기로 보내는 방식인 차콜 캐니스터 방식(Charcoal Canister System)으로 크게 구분된다.In general, since gasoline vapors generated from fuel systems like fuel tanks are hydrocarbons, they pollute the atmosphere, and thus, they are introduced into a combustion chamber without being released into the atmosphere, and the fuel evaporation gas emission suppression device is a vaporized gas in the tank. Is stored in the crankcase and delivered to the combustion chamber using a blow-by gas reducing device, and a method of adsorbing and storing evaporated gas into activated carbon and sending it to the vaporizer together with the outside air. It is largely classified into a charcoal canister system.
이중 종래의 차콜캐니스터 방식은 제 3도에 도시된 바와 같이, 엔진부위에 구비되어진 기화기(101)에 연결된 차콜캐니스터(102)가 아웃파이프(106)를 매개로 연료탱크(103)로 이어지는데, 상기 연료탱크(103)에는 외주면에서 소정간격으로 떨어져 구비된 2개의 밸브(104,104')에 연결된 인너파이프(105)가 연료탱크(103)의 외부에 구비되고, 상기 인너파이프(105)가 연결된 한쪽 밸브(104')에서 차체를 따라 이어진 아웃파이프(106)가 차콜캐니스터(102)로 연결 되어진다.In the conventional charcoal canister system, as shown in FIG. 3, the charcoal canister 102 connected to the carburetor 101 provided at the engine portion is connected to the fuel tank 103 via the outpipe 106. In the fuel tank 103, an inner pipe 105 connected to two valves 104 and 104 ′ provided at a predetermined interval from an outer circumferential surface is provided outside the fuel tank 103, and one valve to which the inner pipe 105 is connected. An outpipe 106 running along the vehicle body at 104 'is connected to the charcoal canister 102.
따라서 연료탱크(103)내의 증기압이 상승하면 밸브(104)가 열려 증발가스가 인너파이프(105)로 유입되고 이로 인해 아웃파이프(106)에 연결된 밸브(104')가 열리면서 아웃파이프(106)를 통해 차콜캐니스터(102)로 증발가스가 유입/흡착되어 외기와 함께 기화기로 재공급 된다.Therefore, when the vapor pressure in the fuel tank 103 rises, the valve 104 opens to allow the boil-off gas to flow into the inner pipe 105, thereby opening the valve 104 ′ connected to the out pipe 106, thereby opening the out pipe 106. The evaporated gas is introduced / adsorbed into the charcoal canister 102 and is supplied back to the carburetor together with the outside air.
그러나, 종래의 연료 증발가스 배출억제장치에서 상기 차콜 캐니스터(102)로 증발가스를 유입시키기 위해 연료탱크(103) 외주면에 구비된 2개의 밸브(104,104') 사이에 설치된 인너파이프(105)로 인해 상기 연료탱크(103)의 차체 장착시 소정의 간격을 확보시켜야만 하므로 상대적으로 노면과의 높이가 낮아져 노면의 복사열 내지는 돌과 같은 지상의 장애물로 부터 간섭을 받을 뿐만 이니라, 상기 인너 파이프(105)로 인해 연료탱크(103)가 장착되어지는 부위의 차체형상이 복잡해지는 등의 문제점이 있었다.However, due to the inner pipe 105 installed between the two valves 104 and 104 'provided on the outer circumferential surface of the fuel tank 103 in order to introduce the boil-off gas into the char canister 102 in the conventional fuel boil-off gas emission suppression apparatus. Since the fuel tank 103 must be secured at a predetermined distance when the vehicle body is mounted, the height of the fuel tank 103 is relatively lowered, thereby not only receiving interference from ground obstacles such as radiant heat or stones on the road, but also to the inner pipe 105. As a result, the shape of the vehicle body of the portion where the fuel tank 103 is mounted is complicated.
이에 본 고안은 상기와 같은 문제를 해소하기 위해 안출된 것으로, 노면으로부터 상대적으로 연료탱크의 높이를 높게하여 가솔린 증발가스 경로에 노면의 복사열으로 인한 영향을 줄일 수 있을 뿐만 아니라, 연료탱크가 장착되는 차체의 형상도 단순화 시킬 수 있도록 된 차량 연료탱크의 연료 증발가스 배출억제장치를 제공함에 그 목적이 있다.The present invention has been devised to solve the above problems, by increasing the height of the fuel tank relatively from the road surface to reduce the influence of the radiant heat of the road surface in the gasoline boil-off gas path, the fuel tank is installed It is an object of the present invention to provide a fuel evaporative gas emission suppression device for a vehicle fuel tank, which can simplify the shape of the vehicle body.

상기와 같은 목적을 달성하기 위한 본 고안은, 연료탱크내에 발생된 증발가스의 배출경로인 인너파이프가 2개의 밸브에 구비된 연결부를 매개로 연료탱크내부에 설치되고, 상기 연료탱크의 측면에서 인너파이프가 차체를 따라 차콜캐니스터에 이어진 아웃파이프에 연결되어지는 구조로 되어있다.The present invention for achieving the above object is, the inner pipe which is the discharge path of the boil-off gas generated in the fuel tank is installed in the fuel tank via the connection portion provided in the two valves, the inner side in the fuel tank The pipe is connected to the outpipe along the car body to the charcoal canister.
이하 본 고안을 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안에 따른 연료 증발가스 배출억제장치를 갖춘 연료탱크가 차량 내부에 설치된 개략적인 구성도를 도시한 것으로, 본 고안은 엔진부위에 구비된어진 기화기(1)에 연결된 차콜캐니스터(2)가 아웃파이프(6)를 매개로 연료탱크(3)에 이어지되, 제2도에 도시된 바와 같이, 이 연료탱크(3)의 외주면에 구비되며 연료의 증발시 발생되는 증기압에 의해 작동되는 밸브(4)와 연결된 연결부(5a)를 매개로 상기 밸브(4)에 소정간격 이격되며 증기압에 의해 작동되는 밸브(4')에 인너파이프(5)가 연료탱크(3)의 내부로 연결되고, 이 인너파이프(5)가 연결되어진 밸브(4')에 구비된 연결부(5a')를 매개로 차콜캐니스터(2)에 이어진 아웃파이프(6)가 연결 되어지게 된다.1 is a schematic configuration diagram of a fuel tank equipped with a fuel evaporation gas emission suppression apparatus according to the present invention installed inside a vehicle, and the present invention provides a charcoal canister (2) connected to a vaporizer 1 provided at an engine part. ) Is connected to the fuel tank 3 via the outpipe 6, as shown in FIG. 2, which is provided on the outer circumferential surface of the fuel tank 3 and operated by vapor pressure generated when the fuel evaporates. The inner pipe 5 is connected to the inside of the fuel tank 3 to a valve 4 'which is spaced a predetermined distance from the valve 4 by a connection part 5a connected to the valve 4 and is operated by steam pressure. In addition, the outpipe 6 connected to the char canister 2 is connected through the connection part 5a 'provided in the valve 4' to which the inner pipe 5 is connected.
따라서 연료탱크(3)내의 증기압이 상승하면 밸브(4)가 열려 연결부(5a)를 매개로 인너파이프(5)로 유입되고, 이 인너파이프(5)의 압력 상승으로 인해 상기 밸브(4)와 소정간격으로 떨어져 구비된 밸브(4')가 열리게 됨에 따라 상기 밸브(4')에 구비된 연결부(5a')를 매개로 증발가스가 아웃파이프(6)에서 차콜캐니스터(2)로 유입되어질 뿐만 아니라, 상기 차콜캐니스터(2)로 증발가스를 유입하기 위한 인너파이프(5)가 연료탱크(3) 내부에 구비됨에 따라, 이 연료탱크(3)의 상부구조가 간단하게 이루어져 차체와 연료탱크(3)가 밀착되어 취부되게 된다.Therefore, when the vapor pressure in the fuel tank 3 rises, the valve 4 opens and flows into the inner pipe 5 through the connecting portion 5a, and the pressure of the inner pipe 5 increases with the valve 4. As the valve 4 'provided at a predetermined interval is opened, the evaporation gas is introduced into the char canister 2 from the outpipe 6 through the connection portion 5a' provided at the valve 4 '. In addition, as the inner pipe 5 for introducing the boil-off gas into the char canister 2 is provided in the fuel tank 3, the upper structure of the fuel tank 3 is made simple and the vehicle body and the fuel tank ( 3) is attached in close contact.
이상 설명한 바와 같이 본 고안에 따르면, 증발가스를 차콜캐니스터로 보내기 위한 인너파이프가 연료탱크 내부에 구비되어져, 상기 연료탱크가 차체에 밀착 장착되므로 차체의 장착 부위형상이 단순할 뿐만 아니라, 상기 연료 탱크의 높이가 노면으로부터 상대적으로 높아져서 노면으로부터 전달되는 복사열의 전달을 줄이고 돌이나 지상의 장애물로부터 연료탱크와의 간섭을 방지하여 안전성을 향상시키는 효과가 있다.As described above, according to the present invention, an inner pipe for sending boil-off gas to the charcoal canister is provided inside the fuel tank, and the fuel tank is closely attached to the vehicle body, so that the shape of the mounting portion of the vehicle body is not only simple, but also the fuel tank. The height of R is relatively high from the road surface, thereby reducing the transfer of radiant heat transmitted from the road surface, and preventing the interference with the fuel tank from stones or ground obstacles, thereby improving safety.
