Abstract (en)
[origin: EP4082667A1] An electrostatic precipitator includes a plurality of precipitation portions, each including a charging electrode configured to charge a particulate matter contained in an exhaust gas of an engine by generating a corona discharge; and a collection electrode configured to collect by a Coulomb force the particulate matter charged by the corona discharge. The precipitation portions are arranged in series with respect to a flow of the exhaust gas.
