Theoretical and Experimental Research on the Characteristics of Micro-length Fiber Carbonized Wood DPF

摘要

The Diesel powered vehicles produce a considerable amount of particulate laden exhaust gases, which is thought to be the main source of air pollution and also cause lung cancer. The diesel particulate filter (DPF) is one of the leading technologies for reducing diesel particulate matter (PM). In this paper, the method of utilizing micro-length fiber carbonized wood (MLFCW) as filter material of DPF is presented for the first time. Theory and test prove that the filter efficiency of the MLFCW DPF is high, the exhaust back pressure low and service life long, which can successively open up a new direction for reducing diesel PM.
