| 简介 |
The method for cleaning exhaust gas of a diesel engine (1), comprises guiding the exhaust gas into an exhaust gas tract (4) of the diesel engine by a catalyst (2) and a particle filter (3) for binding the soot particles, where the catalyst and/or the particle filter are coated with a coating, which has an element such as rare earth metal that is present in form of a salt or oxide or element. The particle filter is actively regenerated during reaching a predetermined exhaust gas back pressure in the exhaust gas tract.

The particle filter is actively regenerated during reaching a predetermined exhaust gas back pressure in the exhaust gas tract. The particle filter is regenerated by injecting a fuel into the exhaust gas tract before the catalyst, which has two elements. The coating has two or more elements in a concentration of 300.0-50000.0 g/m 3>, and has a lower coating layer on which an upper coating layer containing the rare earth metal is deposited. The upper coating layer has particles of crystalline silicon oxide or a glass-like silicon oxide-phase, whose average particle size of less than 100 nm. |
