Abstract
(목적)(purpose)
본 발명은 자동차 배기가스 촉매변환기의 과열상태를 검출하여 미리 경고함으로써, 촉매변환기의 고장을 미연에 방지하기 위한 것이다.The present invention is intended to prevent malfunction of the catalytic converter by detecting and warning the overheated state of the automobile exhaust gas catalytic converter.
(구성)(Configuration)
본 발명의 자동차 배기가스 촉매변환기의 과열 경고장치는, 배기가스를 삼원촉매로 정화시키는 촉매변환기(20)의 온도를 감지하도록 온도센서(100)를 설치하고, 전자제어장치(10)가 상기한 온도센서(100)의 감지온도가 규정온도 이상으로 과열되는 경우를 판단하여 계기판의 표시램프(200)를 통해 고장 경고 표시를 하도록 구성함에 특징이 있다.An overheat warning device for an automobile exhaust gas catalytic converter of the present invention includes a temperature sensor 100 for detecting the temperature of a catalytic converter 20 for purifying an exhaust gas with a three way catalyst, It is determined that the temperature sensed by the temperature sensor 100 is overheated to a predetermined temperature or more and a failure warning is displayed through the display lamp 200 of the instrument panel.
