Abstract

가솔린 자동차가 정상적인 난기 운전에서는 연소된 가스가 촉매 컨버터를 지나면서 연소 가스의 유해성분을 화학 반응으로 제거시키고 대기중으로 방출한다. 그러나 자동차가 시동 초기 등의 냉시동시에는 촉매 컨버터가 정상 작동 온도에 도달하지 않아 배출 가스의 유해 성분을 제거하지 못하고 그대로 대기중에 방출된다.In normal turbulent operation of gasoline cars, the burned gas passes through a catalytic converter to remove harmful components of the combustion gases by chemical reactions and release them into the atmosphere. However, when the car is cold-started, such as at the start of the start, the catalytic converter does not reach the normal operating temperature and thus does not remove harmful components of the exhaust gas and is released into the atmosphere.

이러한 문제점을 해결하기 위하여 이 장치는 가솔린 자동차의 시동 초기 등 냉시동시 촉매 컨버터가 작동 온도에 도달하는 시기를 앞당기도록 겹 관과 겹외피형 촉매 컨버터가 설치된다.In order to solve this problem, the device is equipped with a double pipe and a double skin type catalytic converter to speed up the timing when the catalytic converter reaches the operating temperature during cold start, such as the start-up of a gasoline vehicle.

또 촉매가 정상 작동 온도에 미도달한 상태에서는 연소 가스가 머플러를 거쳐 대기중으로 방출되지 못하게 제어 댐퍼로 억제하는 한편, 연소 가스를 흡기구로 우회시키고, 그 연소 가스 중의 불순물을 여과시킨다. 이 여과된 연소 가스는 인접한 공기 청정기로 들어가 대개 공기와 섞여 연소실에서 연소된 뒤 촉매 컨버터로 나온다.In the state where the catalyst has not reached the normal operating temperature, the combustion gas is suppressed by the control damper to prevent the combustion gas from being released into the atmosphere through the muffler, while the combustion gas is diverted to the intake port, and impurities in the combustion gas are filtered out. This filtered combustion gas enters an adjacent air purifier, which is usually mixed with air, combusted in the combustion chamber, and exits the catalytic converter.

이런 과정이 반복되면 대부분의 연소 가스가 촉매 컨버터를 예열하게 되고, 일부가 제어 댐퍼에 부착된 더머스태틱 코일을 가열하면서 머플러를 거쳐 대기중으로 방출된다. 그러면 더머스태틱 코일에 연동된 제어 댐퍼가 작동하여 촉매 컨버터에서 머플러로 통로를 열고 흡기구를 막는다.When this process is repeated, most of the combustion gases preheat the catalytic converter and some are released through the muffler into the atmosphere, heating the thermostatic coils attached to the control dampers. The control damper associated with the dermastatic coil is then activated to open the passage from the catalytic converter to the muffler and close the intake vents.

자동차 기관이 충분히 난기되지 않는 상태, 즉 냉시동시에도 유해 가스를 배출하지 않는 장치이다.It is a device that does not emit harmful gas even when the engine is not sufficiently warm, that is, cold start.
