Abstract (en)
[origin: WO2016175697A1] An exhaust gas treatment system (4) comprising a selective catalytic reduction catalyst (7) and a method for providing a desired ratio between NO2 and NOx in the exhaust gas intended to pass a selective catalytic reduction catalyst (7) are disclosed. The flow of exhaust gas is in the system is divided into two partial flows wherein NO is oxidised to a low degree in the first partial flow and to a high degree in the second partial flow. The exhaust gas treatment system (4) and the method enables a high conversion rate in the SCR for a large range of operating parameters in terms of temperature and mass flow.
