본 고안은 자동차용 초기 배기가스 저감장치에 관한 것으로, 특히 산화촉매컨버터에 분자필터트랩을 설치하여 촉매의 미작동시 배기가스를 거를 수 있게 한 배기가스 저감장치에 관한 것이다.The present invention relates to an early exhaust gas reduction device for automobiles, and more particularly to an exhaust gas reduction device that can filter the exhaust gas when the catalyst is not operated by installing a molecular filter trap in the oxidation catalyst converter.
일반적으로 휘발유를 사용하는 자동차는 크랭크 케이스에서 배출되는 블로바이 가스, 연료탱크와 기화기의 연료가 증발하여 발생하는 증발가스, 연소시 배출되는 배기가스 등으로 대기를 오염시키고, LPG 연료를 사용하는 자동차는 크랭크 케이스에서 블로바이 가스와 연소시 배출되는 배기가스로 대기를 오염시키게 되는데 이때 이러한 각종 배출가스를 효과적으로 감소시키기 위하여 각 차량에는 배기가스 저감장치를 설치하여서 산화촉매 컨버터에 의해 연소기 발생하는 배기가스중 유해가스를 무해가스로 변환시키게 되어 있다.In general, a car using gasoline pollutes the atmosphere with a blow-by gas discharged from a crankcase, an evaporation gas generated by evaporation of fuel from a fuel tank and a carburetor, and an exhaust gas emitted from combustion, and uses an LPG fuel. In the crank case, the air is polluted with the blow-by gas and the exhaust gas emitted during combustion. At this time, in order to effectively reduce these various exhaust gases, each vehicle is equipped with an exhaust gas reducing device, and the exhaust gas generated by the combustion catalyst by the oxidation catalyst converter is installed. It is supposed to convert heavy gas into harmless gas.
그러나, 이와 같은 산화촉매컨버터는 촉매가 일정온도(대략 300℃)에서만이 성능을 발하게 되므로 촉매의 온도가 가열되기전(예컨대 시동후 엔진이 예열되기전)에는 촉매작용을 하지 않게 되어 각종 배기가스가 변환되지 않고 그대로 배출하게 되어 대기를 오염시키게 된다.However, such an oxidation catalyst converter does not catalyze before the catalyst is heated (e.g. after the engine is preheated) because the catalyst only performs at a constant temperature (about 300 ° C). Will not be converted and will be discharged as is, contaminating the air.
따라서, 본 고안은 이와 같은 점을 감안하며 안출한 것으로, 저온일때 촉매작용이 되지 않아 그대로 배출되는 유해가스(HC)를 포집할 수 있는 분자필터트랩을 설치하고 이를 선택적으로 개폐하는 밸브를 설치하여서 촉매가 성능을 발휘하기 전까지 배기가스가 필터를 통하게 함으로써 유해한 배기가스를 무해하게 변환시켜 배출될수 있도록 한 것이다.Therefore, the present invention has been devised in consideration of such a point, and by installing a molecular filter trap capable of capturing noxious gas (HC) which is discharged as it is not catalytically at low temperatures, and by installing a valve to selectively open and close it, Exhaust gas is passed through the filter until the catalyst performs, so that harmful exhaust gas is harmlessly converted and discharged.
이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.When described in detail based on the accompanying drawings as follows.
본 고안은 산화촉매컨버터(1)가 설치된 주기판(2)에 있어서, 상기 산화촉매컨버터(1) 전후에 우회기관(3)을 연통되게 설치하고, 산화촉매컨버터(1)를 지난 뒷쪽의 주기관(2)에 펌프(4)가 설치된 분자필터트랩(5)이 우회기관(3)에 연통되게 설치하되, 상기 주기관(2)과 우회기관(3)에 연결접속된 분자필터트랩(5) 양단부에는 선택적으로 개폐가능한 밸브(6,6')를 설치하여 이루는 초기 배기가스 저감장치이다.According to the present invention, in a main board (2) provided with an oxidation catalyst converter (1), the main engine (2) is installed so as to communicate with the bypass engine (3) before and after the oxidation catalyst converter (1), and after passing the oxidation catalyst converter (1). Molecular filter trap (5) having a pump (4) installed in (2) is installed in communication with the bypass engine (3), the molecular filter trap (5) connected to the main engine (2) and the bypass engine (3) It is an initial exhaust gas reduction device formed by providing valves 6 and 6 'which can be selectively opened and closed at both ends.
여기서, 밸브(6)는 주기관(2)의 배출구(A)와 분자필터트랩의 입구(B)를 선택적으로 개폐하며, 밸브(6')는 우회기관(3)의 전(A') 후(B')를 선택적으로 개폐하게 하되 상기 양 밸브(6, 6')는 동시에 작동되게 한다.Here, the valve 6 selectively opens and closes the outlet (A) of the main engine (2) and the inlet (B) of the molecular filter trap, the valve (6 ') before (A') after the bypass engine (3) Selectively opening and closing (B ') while allowing both valves 6 and 6' to operate simultaneously.
이때 밸브(6 6')의 조작은 온도감지센서나 운전석에서의 조작레버 등으로 작동될 수 있게 구성하는 것으로 이 분야의 통상의 지식을 가진자는 용이하게 실시할 수 있는 것이므로 이에 대한 설명을 생략한다.In this case, the operation of the valve 6 6 ′ is configured to be operated by a temperature sensor or an operating lever in the driver's seat, which is easily performed by those skilled in the art, and thus description thereof will be omitted. .
이와 같이 구성된 본 고안은 시동후 촉매가 일정온도로 가열되기전, 즉 촉매에 의해 유해한 배기가스가 무해한 성분으로 변환되게 작용될 수 있는 온도가 되기전의 초기상태에는 밸브(6,6')를 전(A')과 배출구(A)위치로 이동하게 하여서 산화촉매컨버터(1)를 지나 촉매작용으로 변환되지 않은 상태의 배기가스가 분자필터트랩(5)을 통해 배출하게 되므로써 촉매작용이 되지 않는 배기가스의 유해성분(HC등)이 상기 트랩(5)을 지나면서 필터에 포집되게 한다.In this configuration, the valve (6,6 ') is opened in the initial state after the start of the catalyst before the catalyst is heated to a constant temperature, that is, a temperature at which the harmful exhaust gas can be converted into a harmless component by the catalyst. Exhaust gas which is not catalyzed by exhaust gas through the molecular filter trap 5 which is not converted into catalytic action through the oxidation catalyst converter 1 by moving to the position A 'and outlet A. Harmful components of gas (HC, etc.) are trapped in the filter while passing through the trap (5).
이와 같이 배출시킨 다음 온도가 상승하여 산화촉매컨버터에서 촉매작용을 하게 되면 밸브(6,6')는 후(B')와 트랩입구(B)로 이동시켜 배기가스가 산화촉매컨버터(1)를 지나면서 촉매에 의해 무해성분으로 변환되게 하면 배출시키게 된다.After discharged in this way, when the temperature rises and catalyzes in the oxidation catalyst converter, the valves 6 and 6 'move to the rear (B') and the trap inlet (B) so that the exhaust gas moves the oxidation catalyst converter (1). Over time, if converted into a harmless component by the catalyst will be discharged.
이때 분자필터트랩(5)에 포집되어 있던 유해성분은 펌프(4)의 작동으로 우회기관(3)을 통해 산화촉매컨버터(1)를 통해 테일파이프(7)로 배출되게 한다.At this time, the harmful components collected in the molecular filter trap (5) is discharged to the tail pipe (7) through the oxidation catalyst converter (1) through the bypass pipe (3) by the operation of the pump (4).
이와 같이 본 고안은 엔진이 가열되기전 즉, 촉매에 의해 배기가스의 유해성분이 무해성분으로 변환시키는 동작이 되기 전에는 배기가스가 본 고안의 분자필터트랩을 통과하게 함에 따라 배기가스의 유해성분을 거를 수 있게 하여 배출되게 하고, 일정온도가 상승하여 촉매작용이 될때에는 산화촉매컨버터를 통해 배출되게 함으로써, 엔진시동 초기단계에서 촉매가 작용되지 않아 유해성분이 배출되는 것을 막을 수 있어 대기오염을 방지할수 있는 특장점이 있는 것이다.As such, the present invention removes the harmful components of the exhaust gas as the exhaust gas passes through the molecular filter trap of the present invention before the engine is heated, that is, before the operation of converting the harmful components of the exhaust gas into the harmless components by the catalyst. When it is catalyzed by rising temperature, it is discharged through oxidation catalyst converter, which prevents harmful pollution by preventing catalyst from being released during the initial stage of engine start-up. There are advantages.
