EXHAUST CLEANING DEVICE FOR INTERNAL COMBUSTION ENGINES |
摘要 |
The present device for purifying the exhaust gas of an internal combustion engine comprises a particulate filter 70 arranged in the exhaust system and reversing means 71 for reversing the exhaust gas upstream side and the exhaust gas downstream side of the particulate filter. The trapped particulates are oxidized on the particulate filter, and the particulate filter has a trapping wall for trapping the particulates. The trapping wall has a first trapping surface and a second trapping surface. The reversing means reverses the exhaust gas upstream side and the exhaust gas downstream side of the particulate filter so that the first trapping surface and the second trapping surface are used alternately to trap the particulates. <IMAGE> |
