Abstract

자동차의 배기 파이프에 위치하는 촉매컨버터에 내장된 촉매성분의 열화정도를 나타내는 캐털리스트 모니터링 시스템에 있어서; 촉매컨버터 내의 촉매성분이 열화됨에 따라 발생되는 발열량에 따른 온도상승 차(△T)가 스레쉬홀드 포인트(△T')일때 밀(mil)점등이 되도록하여 촉매성분의 열화정도를 판정케 하기 위하여; 연소실에서 배출되는 배기가스를 정화할 촉매를 내장하며, 배기가스의 유입, 유출을 가능케 하는 입구와, 출구를 포함하는 촉매컨버터와, 이 촉매컨버터의 입구와, 촉매중앙부 또는 출구부에 열전대를 설치하여 2개의 열전대의 온도차를 이용한 촉매의 비활성을 판정하는 구조로 이루어짐을 특징으로 하는 캐털리스트 모니터링 시스템.A catalyst monitoring system for indicating a degree of deterioration of a catalyst component embedded in a catalytic converter located in an exhaust pipe of an automobile; In order to determine the degree of deterioration of the catalyst component so that the temperature rise difference (△ T) according to the amount of heat generated by the deterioration of the catalyst component in the catalytic converter becomes a mil light when the threshold point (△ T ') ; Built-in catalyst to purify the exhaust gas discharged from the combustion chamber, a catalytic converter including an inlet and an outlet to enable the inflow and outflow of exhaust gas, and an inlet of the catalytic converter, and a thermocouple at the central portion or outlet of the catalyst converter. Catalytic monitoring system, characterized in that consisting of a structure for determining the inactivity of the catalyst using the temperature difference of the two thermocouples.
