Abstract:
1. A method for regenerating a particle filter ( 13 ) arranged in thermic connection to a catalyzer unit ( 14 ) in an exhaust canal ( 10 ) connected to an internal combustion engine ( 2 ), and wherein the internal combustion engine ( 2 ) is arranged to assume a first operational mode ( 60 ) in which a driving torque is produced and a second operational mode ( 80 ) which constitutes engine braking, where the internal combustion engine ( 2 ) supplies a compression work to a gas mixture which flows through the internal combustion engine ( 2 ) and the exhaust canal ( 10 ) without a corresponding expansion work having been emitted from the gas mixture, said method comprising: determining, using a control unit ( supplying fuel, via an injection unit ( exposing the catalyzer unit (
