Abstract

The perovskite catalyst in diesel exhaust purifying and four-way-catalyst device were studied on characteristics of the diesel.The specific surface area,thermal stability and structural were tested in the BET,DTA and XRD.The ignition temperature of carbon particle was effected perovskite catalyst.Decontamination effect of four-way-catalyst diesel exhaust was tested,Analysis results show that CO and HC emissions are reduced outnumber 90%,NO are reduced about 60%,a solid content about 90% are filtered.
