Electrostatic filter for removing soot particles from internal combustion engine exhaust gases comprises at least one filtration cell and includes a catalyst disposed in the gas flow path in each cell

摘要

Electrostatic filter for removing soot particles from internal combustion engine exhaust gases, comprising at least one filtration cell (7) with a high-voltage central electrode (14) passing through a gas passage (10) surrounded by a gas-permeable outer electrode (8), includes a catalyst disposed in the gas flow path in each cell to promote oxidation of soot particles, carbon monoxide, unburned hydrocarbons and/or nitrogen oxides.
