摘要
FIELD: engines and pumps.;SUBSTANCE: proposed method comprises estimation of ageing of catalytic reduction device 3 used for neutralisation of waste gases. In compliance with this invention, ageing of catalytic reduction device 3 used for neutralisation of waste gases is defined by relationship between content of hydrocarbons present in offgas and conversion of nitrogen oxide by selective reduction catalyst 5.;EFFECT: efficient determination of ageing of catalytic reduction device used for neutralisation of waste gases.;10 cl, 6 dwg
