Abstract

엔진의 냉각 상태에 따라 배기 도관내에 장착되어 있는 촉매 장치의 위치를 변화시켜 신속하게 촉매 장치가 활성화될 수 있도록 하여 촉매 장치의 정화 효율을 향상시킬 수 있도록 하는 정화 효율을 향상시키기 위한 촉매 위치 가변 장칭 및 그 제어 방법을 제공하기 위하여, 엔진의 냉각수 온도에 따라 내부의 저항값이 변화하여 출력되는 전기 신호의 상태가 변화하는 엔진 냉각수 온도 감지 수단과; 상기 엔진 냉각수 온도 감지 수단에서 출력되는 신호를 판독하여 엔징의 냉각 정도를 판정하고, 판정된 온도에 따른 설정 위치로 촉매 장치의 위치를 변화시킬 수 있는 제어 신호를 출력하여 시동초기 배기 가스에 의한 촉매 장치의 활성 시간을 단축시킬 수 있도록 하는 동작 제어 수단과; 상기 동작 제어 수단에서 출력되는 제어 시호에 따라 동작 상태가 변화하여 촉매 위치를 가변시킬 수 있도록 하는 구동 수단과; 상기 구동 수단과 연결되어 있고, 구동 수단의 동작 상태에 따라 촉매 장치가 장착되어 있는 도관의 길이가 변화하여 촉매 장치의 장착 위치를 변화시키는 배기 도관을 포함하여 이루어져 있다.Catalyst position variable device for improving the purification efficiency to improve the purification efficiency of the catalyst device by changing the position of the catalyst device mounted in the exhaust conduit according to the cooling state of the engine to enable the catalyst device to be activated quickly And an engine coolant temperature sensing means for changing a state of an electrical signal output by changing an internal resistance value according to the coolant temperature of the engine to provide a control method thereof. Read the signal output from the engine coolant temperature sensing means to determine the degree of cooling of the engine, and output a control signal capable of changing the position of the catalytic apparatus to the set position according to the determined temperature to output the catalyst by the initial exhaust gas. Operation control means for shortening the activation time of the apparatus; Drive means for varying the catalyst position by changing the operation state according to the control time signal output from the operation control means; And an exhaust conduit connected to the drive means, the length of the conduit in which the catalyst device is mounted varies depending on the operating state of the drive means, thereby changing the mounting position of the catalyst device.
