FIELD: engines and pumps.
SUBSTANCE: exhaust system 10 for ICE 12 running on lean mixes comprises first monolytic carrier including catalyst for nitrogen oxide (NO) oxidation and second monolytic carrier 18 arranged there behind and composed of filter with flow passing through the walls and having inlet and discharge channels/ Note here that inlet channels comprises catalyst absorbing NOx 20 while discharge channels comprises catalyst 22 for selective catalytic reduction of nitrogen oxides by nitrogen-bearing reducing agent.
EFFECT: higher efficiency of exhaust gas cleaning.
