Abstract
A device for purifying the exhaust gas of an internal combustion engine is disclosed. The device has a particulate filter, arranged in the exhaust system, on which the trapped particulates are oxidized. The engine can be operated in a first operating mode in which it is given priority to improve the fuel consumption rate thereof and a second operating mode in which it is given priority to regenerate the particulate filter to oxidize the trapped particulates. One of the first operating mode and the second operating mode is selected to operate the engine at need.
