Abstract

본 발명은 엔진(1)의 배기계에 설치된 엔진(1)의 배기가스 성분을 흡착하는 흡착장치(2) 중 흡착한 미연소성분을 효과적으로 정화시키는 에어 펌프(4)에 의한 배기가스 정화장치를 제공함에 있다.The present invention provides an exhaust gas purification device by an air pump (4) for effectively purifying the unburned components adsorbed in the adsorption device (2) for adsorbing the exhaust gas components of the engine (1) installed in the exhaust system of the engine (1). Is in.

또한, 엔진(1) 배기계에는 미연소 성분을 흡착시키는 흡착장치(2)와 그 아래에는 해당 배기계에 공기를 공급하는 에어 펌프(4) 및 에어 공급통로 그 아래에는 가열 기능을 가진 촉매(6:EHC)와 주 촉매(8)로 구성되어 있어서 엔진(1)의 흡기계에는 연료를 공급하는 Inj(3)가 설치되어 있고 Inj(3) 및 에어 펌프(4)는 C/Unit에 의해 제어된다. 또한, C/Unit은 엔진(1)의 운전상태를 검출하는 센서의 출력이 입력된다.In addition, the engine 1 exhaust system has an adsorption device 2 for adsorbing unburned components, an air pump 4 for supplying air to the exhaust system, and a catalyst having a heating function under the air supply passage. EJ) and the main catalyst 8, the intake system of the engine 1 is provided with an Inj 3 for supplying fuel, and the Inj 3 and the air pump 4 are controlled by C / Unit. . In addition, the output of the sensor for detecting the operating state of the engine 1 is input to the C / Unit.

흡착장치(2)가 일단 미연소 가스를 흡착한 후 이탈하는 상태를 연료의 적산값이 소정범위 내에 있는 경우에 판정하여 이탈 상태일 때에는 배기계에 에어를 공급하여 가열 기능을 가진 촉매와 주촉매에 효과적으로 미연소가스를 정화시킬 수 있다.When the adsorption device 2 adsorbs the unburned gas and then exits, it is determined when the integrated value of the fuel is within a predetermined range. It can effectively purify unburned gas.
