Exhaust emission control device

摘要

Arranged within a cylindrical housing are capturing cells each including a cylindrical outer electrode capable of capturing particulates and an inner electrode inserted into the outer electrode and lined at its outer surface with a dielectric. A divergent exhaust unit is arranged on an end of the housing so as to guide exhaust to interiors in the respective capturing cells. A convergent exhaust unit is arranged on the other end of the housing so as to communicate with a gap between an inner surface of the housing and outer surfaces of the outer electrodes in the respective cells. The inner and outer electrodes are connected to an electric discharge controller.
