Abstract: According to the requirement of diesel engine particulate reduction, a new kind of sintered metal mesh filter is developed. The experimental study on the characteristics of filtration and flowing resistance of this kind of filter is made, the regeneration system of reverse clearing is designed and preliminary regeneration experiments are made. The results demonstrate that the sintered metal mesh filter has excellent characteristics and can satisfy the requirement of diesel engine particulate reduction, and the technology of filter reverse clearing is feasible.

Key words: Diesel engine, Particulate, Reverse clearing, Sintered metal mesh filter
