Abstract

본 발명은 자동차용 배기장치에 관한 것으로서, 보다 상세하게는 배기관에 바이패스관과 밸브를 구비하여 촉매 컨버어터에 고온의 배기가스의 열로 인하여 촉매 컨버어터의 손상되는 것을 방지하여 배기가스를 절감시킬 수 있는 자동차용 배기장치에 관한 것으로서, 배기매니포드의 하단과 결합된 배기관에 배기관 보다 긴 유로를 가지며 배기가스를 촉매 컨버어터로 이송하는 바이패스관과, 상기 바이패스관의 입구에 설치되어 배기가스가 배기관 또는 바이패스관중 선택된 방향으로 흐르도록 제어하는 밸브와, 촉매 컨버어터의 온도를 감지하여 전기적 신호로 변환출력하는 온도감지센서와, 상기 온도감지센서의 설정값과 비교판단하여 설정값 이상일때 배기가스가 바이패스관으로 흐르도록 상기 밸브를 제어하는 제어부로 구성된 것을 특징으로 하는 자동차용 배기장치.The present invention relates to a vehicle exhaust apparatus, and more particularly, by providing a bypass pipe and a valve in the exhaust pipe to prevent the damage of the catalyst converter due to the heat of the high temperature exhaust gas in the catalytic converter to reduce the exhaust gas The present invention relates to an exhaust device for automobiles, comprising: a bypass pipe having a longer flow path than an exhaust pipe in an exhaust pipe coupled to an exhaust manifold, and for transporting exhaust gas to a catalytic converter, and installed at an inlet of the bypass pipe. A valve for controlling the gas to flow in the selected direction of the exhaust pipe or the bypass pipe, a temperature sensor for sensing the temperature of the catalytic converter and converting it into an electrical signal, and comparing with the set value of the temperature sensor, the value being equal to or greater than the set value When the exhaust gas flows into the bypass pipe is characterized in that the control unit for controlling the valve Automotive exhaust apparatus.
