Abstract:
An exhaust treatment system and method for the treatment of an exhaust stream from a combustion engine are provided. A first oxidation of compounds comprising one or more of nitrogen, carbon and hydrogen in the exhaust stream is carried out by a first oxidation catalyst. Further, a value (NO2_1/NOx_1)det for a ratio between a first amount of nitrogen dioxide and a first amount of nitrogen oxides leaving said first oxidation catalyst is determined. Active control of at least one parameter related to the combustion engine is carried out, based on the determined value, so that the ratio is impacted. A first additive is supplied into the exhaust stream, following which a first reduction of the first amount of nitrogen oxides is carried out through a catalytic reaction in a catalytic filter, which consists of a particulate filter with an at least partly catalytic coating with reduction characteristics. The catalytic filter is arranged for catching and oxidizing of soot particles, and to carry out the first reduction of the first amount of nitrogen oxides using the first additive.

Claim (Index 29):
A computer program product comprising computer program code stored on a non-transitory computer-readable medium, said computer program product for treatment of an exhaust stream, which results from a combustion in a combustion engine, passes through an exhaust treatment system and comprises nitrogen oxides NO x , wherein said nitrogen oxides NO x  comprise nitrogen monoxide NO and nitrogen dioxide NO 2 , said computer program product comprising computer instructions to cause one or more computer processors to perform the following operations:\n a first oxidation of compounds comprising one or more of nitrogen, carbon and hydrogen in said exhaust stream, wherein said first oxidation is carried out by a first oxidation catalyst, arranged in said exhaust treatment system; a determination of a value (NO 2 _ 1 /NO x _ 1 ) det  for a ratio between a first amount of nitrogen dioxide NO 2 _ 1  and a first amount of nitrogen oxides NO x _ 1  leaving said first oxidation catalyst; an active control of at least one parameter related to said combustion engine based on said determined value (NO 2 _ 1 /NO x _ 1 ) det  for said ratio, wherein said active control impacts on said ratio: a first supply of a first additive into said exhaust stream with the use of a first dosage device, arranged downstream of said first oxidation catalyst; and a first reduction of said first amount of nitrogen oxides NO x _ 1  via a catalytic reaction in 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, which is arranged for catching and oxidizing of soot particles, and to carry out said first reduction of said first amount of nitrogen oxides NO x _ 1 , and wherein said catalytic reaction uses said first additive.
