따라서, 상기 배기가스쿨러를 이용하여 상기 배기가스의 온도를 섭씨 150도 미만으로 유지하여 백연의 발생을 줄인다. 상기 배기가스쿨러가 상기 머플러의 전단에 배치되어, 상기 머플러 내부에 고농도로 포집된 황산성분에 의해서, 상기 배기가스쿨러의 방열판이 부식되는 것이 방지되어 내구성이 향상된다. 상기 머플러 내부에서 증발되어 상기 배기가스쿨러의 방열판에 부착되는 것이 방지되어, 배기가스압력이 상승하거나 쿨링효율이 저감되는 것을 방지할 수 있다. 아울러, 상기 머플러의 전단에 상기 배기가스쿨러를 설치함으로써, 비교적 상기 배기가스쿨러를 설치할 공간이 충분하고, 상기 배기가스쿨러에 연결되는 상기 냉각수공급라인의 길이도 줄어든다.-

Abstract: PURPOSE: A post-processing method of exhaust gas and a system therefor are provided to improve durability by preventing particulates from being excessively collected to a diesel particulate filter. CONSTITUTION: A post-processing method of exhaust gas is as follows. The first particulate collection amount is sensed before an engine is stopped using pressure difference between the front and rear ends of a diesel particulate filter. The second particulate collection amount is sensed when the engine is stopped and re-started using the front and rear ends of the diesel particulate filter. When a difference value between the first and second particulate collection amounts excesses a set value, the estimated particulate collection amount of the diesel particulate filter is calculated. When the estimated particulate collection amount excesses the reference collection amount of the diesel particulate filter(S110), the diesel particulate filter is regenerated.
