Detailed Product Description

 DPF(Diesel Particulate Filter): If the DPF is coated with noble metal (such as Pt, Pd and Rh), The particulate of emission is captured inside thin gas hole or entrance. As it lasts, the cumulated layer become thick, and pressure loss increase. To ensure the performance of engine, when pressure loss reaches some value, it is a must to recycle the filter. The recycle is making the particulate burning, by raising the gas temperature of filter.

The particulate condition is related to the oxygen concentration. Normally, it is burning at 550-650 .Its adopted to raise emission temperature by adjusting throttle, and increase gas temperature with burner. The particulate burning temperature can be decreased by catelyzer, making cumulative particulate burning as soon as possible, thus recover the pressure loss and fitters performance, then the filter is recycled.
