Description

필라네크의 연료증발가스 방출억제장치Pilanek's Fuel Evaporation Control System

본 고안은 연료증발가스 방출억제장치에 관한 것으로, 특히 필라네크내에 잔존하는 연료증발가스를 캐니스터로 보내어 포집되도록함으로써 연료증발가스의 배출을 효과적으로 억제시킬 수 있도록 된 필라네크의 연료증발가스 방출억제장치에 관한 것이다.The present invention relates to a fuel evaporation gas emission suppression apparatus, and in particular, a fuel evaporation gas emission suppression apparatus of the Pilaneek which is capable of effectively suppressing the emission of fuel evaporation gas by sending the fuel evaporation gas remaining in the pilane to the canister to be collected. It is about.

현재 자동차의 배출 가스로 인한 대기의 오염을 방지하는 것이 환경 위생상 중요한 문제로 대두되고 있고, 그 대책도 시급히 요청되고 있는 실정이다.At present, preventing the pollution of the air caused by the emission of automobiles has emerged as an important issue for environmental hygiene, and the countermeasures are urgently required.

그리고 자동차에서 배출되는 배출 가스는 주로 배기 파이프에서 나오는 배출 가스와, 기관의 크랭크케이스에서 나오는 블로바이 가스 및, 연료 탱크 등에서 증발하는 연료증발가스가 있다.Exhaust gases emitted from automobiles mainly include exhaust gases from exhaust pipes, blow-by gases from engine crankcases, and fuel evaporation gases from fuel tanks.

상기와 같은 자동차의 배출가스를 억제하기 위해 종래의 배기가스 대책은, 연소실을 비롯하여 연료, 점화, 흡배기 계통을 종합적으로 개량하거나 연소 상태를 제어하는 부가장치를 설치하는 기관개량방식과, 희박한 혼합기를 효율적으로 연소시키기 위해 일부 짙은 혼합기를 동시에 흡입시키는 성층 급기 연소방식, 기관의 각 부분을 개량함과 더불어 동시에 실린더에서 배출된 직후의 배기 가스를 단열재로 감싼 더어멀 리액터로 유도하여 고온 상태를 유지하면서 공기를 불어 넣어 재연소시키는 더어멀 리액터 방식 및, 기관의 각 부분을 개량함과 동시에 유해가스를 산화 또는 환원 촉매로 제거하는 촉매 컨버터 방식이 있다.Conventional exhaust gas countermeasures for suppressing the exhaust gas of automobiles include an engine improvement method including a combustion chamber, an engine improvement system for comprehensively improving the fuel, ignition and intake / exhaust systems, or installing an additional device for controlling combustion conditions, and a lean mixer. In order to efficiently burn, the stratified air supply combustion method which sucks some thick mixers at the same time, improves each part of the engine, and at the same time guides the exhaust gas immediately after discharged from the cylinder to the thermal reactor wrapped with insulation to maintain a high temperature state. There is a thermal reactor method that blows air to reburn and a catalytic converter method that improves each part of the engine and removes harmful gases with an oxidation or reduction catalyst.

그리고 블로바이 가스의 대책은, 블로바이 가스를 대기로 방출시키지 않고 재연소하기 위해 크랭크케이스에서 흡기계통으로 다시 보내는 블로바이 가스 환원장치가 사용되고 있다.As a countermeasure against blow-by gas, a blow-by gas reducing apparatus is used, which is sent back from the crankcase to the intake pipe in order to reburn without blowing the blow-by gas into the atmosphere.

한편 연료탱크에서 증발한 가솔린의 증기를 일시적으로 저장했다가 엔진이 운전할 때에 흡기계통으로 보내어 연소시키는 방식이 사용되고 있는데, 그 방법은 연료탱크 안의 가솔린 증기를 크랭크케이스 안에 저장했다가 블로바이 가스 환원장치를 이용하여 연소실로 보내서 연소시키는 크랭크케이스 저장방식과 , 가솔린 증기를 활성탄으로 흡착시켜 저장하였다가 외기와 함께 흡기계통으로 보내어 재연소시키는 차콜 캐니스터 방식, 연료탱크의 가솔린 증기를 증기분리기로 분리한 다음에 체크밸브를 통해 공기청정기 케이스 안으로 보내어 저장했다가 엔진이 운전될 때에 흡기와 함께 보내어 재연소시키는 공기청정기 케이스방식이 있다.On the other hand, a method of temporarily storing the vapor of gasoline evaporated from the fuel tank and sending it to the intake tank when the engine is operating is used. The method is to store gasoline vapor in the fuel tank in a crankcase and then blow-by gas reducing device. The crankcase storage method to send the combustion chamber to the combustion chamber for combustion, the charcoal canister system to adsorb and store the gasoline vapor with activated carbon, and then send it to the intake pipe together with the outside air for recombustion There is an air purifier case that sends it through the check valve into the air purifier case, stores it, and sends it to the intake air when the engine is running.

도 1은 상기한 종래의 캐니스터방식에 사용되는 캐니스터와 필라네크를 도시한 것인 바, 즉 연료탱크의 상부에 캐니스터(11)가 연통되게 연결되고, 또 차체내부에 장착되는 연료탱크에 외부에서 연료를 용이하게 주입할 수 있도록 연료탱크의 상부에 필라네크(12)가 연통되게 설치되어 있다.1 shows a canister and a pilanek used in the conventional canister method, that is, the canister 11 is connected to the upper portion of the fuel tank so as to be in communication with the fuel tank mounted inside the vehicle body from the outside. In order to easily inject fuel, the pillars 12 are installed in communication with the upper portion of the fuel tank.

이에 따라 상기 필라네크(12)를 통해 주입한 연료는 연료탱크내에 저장됨과 더불어 이 저장연료의 증발가스는 호스를 통해 캐니스터(11)에 의해 포집되어 있다가 엔진의 운전중에 흡기계통으로 보내져 재연소되게 되게 있다.Accordingly, the fuel injected through the piranek 12 is stored in the fuel tank and the boil-off gas of the stored fuel is collected by the canister 11 through a hose and sent to the intake pipe during operation of the engine to be reburned. There is.

그런데 상기와 같은 종래의 연료증발가스 회수구조에서는 캐니스터가 증발가스를 적절히 포집하여 대기로 방출되는 것을 억제시키게 되어 있지만, 연료탱크의 상부와 연통되게 장착되어 있는 필라네크에도 연료증발가스가 잔존하게 되고, 이 필라네크에 들어 있는 연료증발가스는 연료를 주입하기 위해 개폐도아를 개방시키게 되면 곧 바로 대기로 방출도어 대기를 오염시키게 되므로, 연료증발가스의 확실한 대기방출을 방지해주지 못하게 되는 결점이 있었다.However, in the conventional fuel evaporation gas recovery structure as described above, the canister properly captures the evaporated gas and suppresses it from being released into the atmosphere. However, the fuel evaporation gas remains in the Pilaneck mounted in communication with the upper portion of the fuel tank. As a result, the fuel evaporation gas contained in the Pilaneck has a drawback that it cannot immediately prevent the emission of the fuel evaporation gas since the evaporation door is polluted to the atmosphere as soon as the opening door is opened for fuel injection.

이에 본 고안은 상기한 결점을 해소하기 위해 안출된 것으로, 피라네크에 들어 있는 연료증발가스를 캐니스터로 보내어 포집되도록 함으로써 필라네크를 통한 연료증발가스의 대기방출을 효과적으로 억제시킬 수 있도록 된 필라네크의 연료증발가스 회수장치를 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above-mentioned drawbacks, and by sending the fuel evaporation gas contained in the pyranek to the canister to be collected, it is possible to effectively suppress the air emission of the fuel evaporation gas through the piranek. The purpose is to provide a fuel evaporation gas recovery device.

상기한 바의 목적을 달성하기 위한 본 고안은, 연료탱크의 증발가스를 캐니스터로 보내기 위해 연료탱크와 캐니스터를 연결하는 벤트호스에 필라네크를 연통되게 연결시키는 연결수단과, 이 연결수단에 연결수단내의 증발가스는 벤트호스로 유출될 수 있도록 하는 반면에 벤트호스 속의 증발가스는 연결수단으로 역류되지 않도록 방지해주는 역류방지수단이 설치된 구조로 되어 있다.The present invention for achieving the above object, the connecting means for connecting the pilanek to the vent hose connecting the fuel tank and the canister to send the evaporated gas of the fuel tank to the canister, and the connecting means connected to the connecting means. The boil-off gas in the vent hose can be discharged to the vent hose, while the boil-off gas in the vent hose has a structure in which a backflow preventing means is provided to prevent the backflow from being connected to the connecting means.

이하 본 고안의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 고안에 따른 연료증발가스 방출억제장치가 장착된 필라네크의 개략적인 사시도인 바, 즉 연료탱크의 증발가스를 캐니스터로 보내기 위해 연료탱크와 캐니스터를 연결하는 벤트호스(1)에 필라네크(2)를 연통더;ㄴ 연결호스(3)가 3방향 콘넥터(4)를 매개로 연통되게 연결되고, 이 연결호스(3)에 연결호스내의 증발가스가 벤트호스로 유출될 수 있도록 하는 반면에 벤트호스 속의 증발가스는, 연결호스로 역류되지 않도록 방지해주는 체크밸브(5)가 설치된 구조로 되어 있다.Figure 2 is a schematic perspective view of a pilanek equipped with a fuel evaporation gas emission suppression apparatus according to the present invention, that is, a pillar in the vent hose (1) connecting the fuel tank and the canister to send the evaporated gas of the fuel tank to the canister The connecting hose (3) is connected in communication with the neck via the three-way connector (4), the evaporation gas in the connecting hose to the connection hose (3) to the vent hose On the other hand, the boil-off gas in the vent hose has a structure in which a check valve 5 is installed to prevent backflow to the connecting hose.

이에 따라 연료탱크내의 연료증발가스의 대부분은 상기 벤트호스(1)를 통해 캐니스터로 보내어져 포집되게 되고, 일부분의 연료증발가스는 상기 필라네크(2)에 잔존하게 되는 데, 이와 같이 잔존하는 연료증발가스는 다시 상기 연결호스(3)를 통해 체크밸브(5)를 거쳐서 3방향 콘넥터(4)를 매개로 벤트호스(1)로 재유입되게 된다.Accordingly, most of the fuel evaporation gas in the fuel tank is sent to the canister through the vent hose (1) and collected, and a portion of the fuel evaporation gas remains in the pilanek (2). The boil-off gas is again introduced into the vent hose 1 through the three-way connector 4 via the check valve 5 through the connection hose 3.

상기와 같이 필라네크(2)에 잔존해 있는 연료증발가스도 연료호스를 통해 벤트호스로 재유입되어짐에 따라 연료를 주입하기 위해 필라네크(2)를 개방시켜도 필라네크를 통한 연료증발가스의 대기방출이 효과적으로 억제되게 되므로, 연료증발가스로 인한 대기오염을 효과적으로 방지해 줄수 있게 되는 것이다.As described above, the fuel evaporation gas remaining in the pilanec 2 is also re-introduced into the vent hose through the fuel hose, so that the atmosphere of the fuel evaporation gas through the pilanec can be opened even when the pilanec 2 is opened to inject the fuel. Since the emission is effectively suppressed, it is possible to effectively prevent the air pollution caused by fuel evaporation gas.

이상 설명한 바와 같이 본 고안에 따른 필라네크의 연료증발가스 방출억제장치에 의하면, 필라네크 내부에 잔존하는 연료증발가스를 벤트호스를 통해 캐니스터로 보내어 포집되도록 함으로써, 필라네크를 통한 연료증발가스의 대기방출을 효과적으로 억제할 수 있을 뿐만 아니라 연료증발가스로 인한 대기오염을 방지해주는 잇점이 있다.As described above, according to the Pilanek fuel evaporation gas emission suppression apparatus according to the present invention, the fuel evaporation gas remaining inside the piranek is sent to the canister through a vent hose to be collected, whereby the atmosphere of the fuel evaporation gas through the piranek is collected. Not only can it effectively suppress emissions, it also has the advantage of preventing air pollution from fuel evaporation gases.
