Abstract

촉매 컨버터를 갖추고 있는 자동차의 배기관에 있어서, 촉매 컨버터(9)의 외주에 하우징(11)을 설치하여 배기가스가 순환할 수 있는 통로(10)가 이루어지도록 하고 상기한 촉매 컨버터(9)의 온도틀 감지하는 온도센서를 전자제어 유닛(2)과 전기적으로 연결하며 이 전자제어 유닛(2)의 출력신호로 솔레노이드 밸브(3)가 작동하도록 하여 진공부압부(4)의 부압이 다이어프램(5)에 작용토록 함으로서 이 다이어프램(5)에 연동하는 제1 및 제2셔터(6)(7)가 상기한 통로(10)의 입구 및 출구를 개폐시켜 배기가스가 촉매 컨버터를 가열시키도록 한 것을 특징으로 하는 자동차용 촉매 급속가열 시스템.In an exhaust pipe of a vehicle equipped with a catalytic converter, a housing 11 is provided on the outer periphery of the catalytic converter 9 so that a passage 10 through which exhaust gas can be circulated is formed, and the temperature of the catalytic converter 9 described above. The temperature sensor for detecting the frame is electrically connected to the electronic control unit 2, and the solenoid valve 3 is operated by the output signal of the electronic control unit 2 so that the negative pressure of the vacuum negative pressure unit 4 is reduced to the diaphragm 5. And the first and second shutters 6 and 7 interlocked with the diaphragm 5 to open and close the inlet and the outlet of the passage 10 so that the exhaust gas heats the catalytic converter. Automotive catalyst rapid heating system.

촉매 컨버터를 갖추고 있는 자동차의 배기관에 있어서, 촉매 컨버터(9)의 외주에 하우징(11)을 설치하여 배기 가스가 순환할 수 있는 통로 (10)가 이루어지도록 하고, 상기한 촉매 컨버터(9)의 온도를 감지하는 온도센서(1)를 전자제어 유닛(2)과 전기적으로 연결하며 이 전자제어 유닛(2)의 출력신호로 솔레노이드 밸브(3)가 작동하도록 하여 진공부압부(4)의 부압이 다이어프램(5)에 작용토록 함으로서 이 다이어프램(5)에 연동하는 제1및 제2셔터 (6)(7)가 상기한 통로(10)의 입구 및 출구를 개폐시켜 배기가스가 촉매 컨버터를 가열시키도록 한 것을 특징으로 하는 자동차용 촉매 급속가열 시스템.In an exhaust pipe of an automobile equipped with a catalytic converter, a housing 11 is provided on the outer periphery of the catalytic converter 9 so that a passage 10 through which exhaust gas can be circulated is formed. The temperature sensor 1 which senses temperature is electrically connected to the electronic control unit 2 and the solenoid valve 3 is operated by the output signal of the electronic control unit 2 so that the negative pressure of the vacuum negative pressure unit 4 is reduced. By acting on the diaphragm 5, the first and second shutters 6 and 7 interlocked with the diaphragm 5 open and close the inlet and outlet of the passage 10 so that the exhaust gas heats the catalytic converter. Automotive catalyst rapid heating system, characterized in that. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임※ Note: The disclosure is based on the initial application.
