An engine exhaust treatment system, comprising an engine exhaust dust removal system and an engine exhaust ozone-purification system. The engine exhaust dust removal system comprises an exhaust electric-field device (1021) and an exhaust cooling device. The exhaust electric-field device (1021) comprises an exhaust electric-field device inlet, an exhaust electric-field device outlet, an exhaust dust removal electric-field cathode (10212), and an exhaust dust removal electric-field anode (10211). The exhaust dust removal electric-field cathode (10212) and the exhaust dust removal electric-field anode (10211) are used for generating an exhaust ionization dust-removal electric field. The exhaust cooling device is used for reducing the exhaust temperature before the exhaust electric-field device inlet. The exhaust cooling device can not only improve fuel economy, but also reduce the exhaust temperature to below the dew point, so as to facilitate the process of electric dust removal and ozone-based exhaust purification that requires a low temperature environment. The engine exhaust treatment system can effectively treat engine emissions and enable the engine emissions to be cleaner. |
