Abstract: The experimental study of the reverse cleaning system of diesel emission particulate metal mesh filter is made, the effect of the structure parameter and operation parameter of the reverse cleaning system of metal mesh filter on the maximum regeneration pressure, maximum pressure time and regeneration efficiency of the diesel particulate metal filter are analyzed, and some useful conclusions are obtained. The results of study are very important to the understanding of the characteristics of the reverse cleaning system of diesel emission particulate metal mesh filter entirely and to the design of the metal mesh filter structure and the reverse cleaning system.

Key words: Diesel engine  Particulate  Metal mess filter  Reverse clearing  Characteristic
