Particle material (PM) emission from a diesel engine was characterized. Effects of dielectric barrier discharge (DBD) reaction channels in a multilayer DBD reactor and discharge power on PM removal were investigated. Results showed that the temperature of exhaust gases and PM total number density increased with the increase of engine output power. PM removal improved with the increasing reaction channels due to the increase in residence time of exhaust gases in the multilayer DBD reactor. When the number of reaction channel was 40, PM removal efficiency was as high as 88%. PM removal increased up to 93% as maximum with increasing discharge power. PM with particle sizes smaller than 200 nm was removed more easily than those bigger than 200 nm．
