Abstract:
본 발명은 엔진의 배기가스를 이용한 요소수용액 동결 방지구조에 관한 것으로, 엔진(1) 및 콤프레셔(1') 그리고 온도센서가 설치된 UREA 탱크(2)와, ECU(3), 배기관(7)을 포함한 터보차져(4), SCR촉매(6), DCU(8) 및 DU(9) 등으로 이루어진 일련의 UREA 동결 방지구조에 있어서, 상기 터보차져(4)와 연결된 배기관(7)의 후단에 배기가스의 개폐 공급을 위한 밸브(5)를 설치하고 상기 밸브(5)와 UREA 탱크(2)를 이중관파이프(2')로 연결함과 아울러 상기 밸브(5)를 ECU(3)와 연결하며 UREA 탱크(2) 내부 온도가 -10 DEG 이하시 UREA 탱크(2)의 온도센서가 이를 감지하여 ECU(3)로 전달하고 상기 전달된 신호에 의해 ECU(3)가 상기 밸브(5)를 개방하여 배기가스의 공급에 의해 UREA의 온도가 상온이 되면 ECU(3)가 다시 개방된 밸브(5)가 차단될 수 있도록 구성된 구조를 특징으로 한다. 본 발명은 엔진 연소후 배출되는 약 300℃~600℃의 고온 고압의 배기가스를 이용하여 요소수용액 탱크(UREA 탱크)를 용이하게 히팅시켜 줌으로서 UREA 탱크 내부에 수용된 UREA의 동결을 방지할 수 있고 터보차져 후단의 배기가스를 이용함으로써 터보차져의 압축성능에 영향을 전혀 주지 않을 뿐 아니라 종래 흡입공기를 이용하는 방법과 비교하여 훨씬 효과적이고 안정적인 장점이 있다.
