Abstract
Description
Claims (1)
- 디젤엔진(10)의 배기통로(12)에 설치되며 배기가스 중에 포함된 미립자를 포집하는 세라믹 필터(31)와, 상기 세라믹 필터(31)를 수용지지하는 캐비티(30)와, 상기 캐비티(30)의 입구측과 출구측의 압력차를 감지하여 상기 세라믹 필터(31)에 포집된 미립자의 포집량을 검출하기 위한 차압감지센서(34)와, 상기 세라믹 필터(31)에 포집된 미립자를 가열하여 착화시키기 위한 전기히터(32)와, 상기 전기히터(32)의 가열로 인한 상기 캐비티(30)내의 온도변화를 감지하여 미립자의 착화여부를 검출하기 위한 열전대센서(35)와, 상기 미립자의 착화시 자체 연소되도록 연소에 필요한 공기를 캐비티내로 공급하는 송풍기(50)를 구비한 디젤엔진 매연 포집장치에 있어서, 상기 열전대센서(35)의 검출정보에 의거하여 포집된 미립자의 착화가 검출되면, 미리 설정된 연소조건에 따른 펄스의 듀티폭을 조절하여 펄스신호를 출력하는 펄스폭변조부(25)와, 상기 펄스폭변조부(25)로부터 출력된 펄스신호에 의거하여 상기 송풍기(50)의 회전속도를 조절함으로써 포집된 미립자 연소시 공급되는 공기량이 조절되도록 상기 펄스폭변조부(25) 및 상기 송풍기(50)와 전기적으로 결선된 PWM구동부(52)로 구성된 것을 특징으로 하는 디젤엔진 매연 포집장치.
