Abstract:
An exhaust treatment system arranged for treatment of an exhaust stream is presented. The exhaust treatment system comprises a first reduction catalyst device arranged for reduction of nitrogen oxides in said exhaust stream through the use of compounds comprising one or several of carbon monoxide and hydrocarbons, which are comprised in said exhaust stream when said exhaust stream reaches said first reduction catalyst device; a particulate filter which is arranged downstream of said first reduction catalyst device to catch and oxidize soot particles in said exhaust stream; a second dosage device arranged downstream of said particulate filter and arranged to supply an additive comprising ammonia or a substance from which ammonia may be extracted and/or released into said exhaust stream; and a second reduction catalyst device, arranged downstream of said second dosage device and arranged for reduction of nitrogen oxides in said exhaust stream through the use of said additive.

Claim (Index 49):
A computer program product comprising computer program code stored on a non-transitory computer-readable medium, said computer program product for the treatment of an exhaust stream resulting from a combustion in a combustion engine, said computer program product comprising computer instructions to cause one or more computer processors to perform the following operations:\n a reduction of nitrogen oxides NO x  in said exhaust stream through the use of a first reduction catalyst device, wherein said reduction is carried out with the use of compounds comprising one or more of carbon monoxide CO and hydrocarbons HC, which are comprised in said exhaust stream when said exhaust stream reaches said first reduction catalyst device; catching and oxidizing of soot particles in said exhaust stream with the use of a particulate filter, which is arranged downstream of said first reduction catalyst device; and a control of supply of an additive comprising ammonia or a substance form which ammonia can be extracted and/or released into said exhaust stream, with the use of a second dosage device arranged downstream of said particulate filter, wherein said supply of said additive impacts a reduction of nitrogen oxides NO x  in said exhaust stream through the use of said additive in a second reduction catalyst device, arranged downstream of said second dosage device.
