Abstract:
An exhaust treatment system comprising: a first oxidation catalyst, to oxidize compounds comprising one or more of nitrogen, carbon, and hydrogen in the exhaust stream; a first dosage device o supply a first additive into an exhaust stream; a catalytic filter, consisting of a particulate filter with an at least partly catalytic coating with reduction characteristics, which is for catching and oxidizing soot particles and for a first reduction of an amount of nitrogen oxides NOx in the exhaust stream with the use of the first additive; a second oxidation catalyst, to oxidize one or more of nitrogen oxide NO and incompletely oxidized carbon compounds in the exhaust stream; a second dosage device to supply a second additive into the exhaust stream; and a reduction catalyst device, arranged for a second reduction of nitrogen oxides NOx in the exhaust stream, with the use of at least one of the first and second additives.

Claim (Index 11):
A method for treatment of an exhaust stream resulting from a combustion in a combustion engine, said method comprising:\n a first oxidation of compounds comprising one or more of nitrogen, carbon and hydrogen in said exhaust stream, with the use of a first oxidation catalyst; a control of a supply of a first additive into said exhaust stream with the use of a first dosage device, arranged downstream of said first oxidation catalyst; catching and oxidizing of soot particles in said exhaust stream, with the use of a catalytic filter arranged downstream of said first dosage device, wherein said catalytic filter consists of a particulate filter with an at least partly catalytic coating with reduction characteristics; a first reduction of nitrogen oxides NOx in said exhaust stream with the use of said first additive and said reduction characteristics of said catalytic filter; a second oxidation of one or more of nitrogen oxides NO and incompletely oxidized carbon compounds in said exhaust stream, with the use of a second oxidation catalyst which is arranged downstream of said catalytic filter; a control of supply of a second additive into said exhaust stream with the use of a second dosage device, arranged downstream of said second oxidation catalyst; and a second reduction of nitrogen oxides NOx in said exhaust stream, with the use of at least one of said first and said second additive in a reduction catalyst device, arranged downstream of said second dosage device.
