FIELD: transport.
SUBSTANCE: invention may be used in engine production. Engine exhaust gas containing NO2 is brought in contact with catalyst. Said catalyst is active in reducing NO2 to NO and comprises, at least, one platinum group metal provided that platinum metal is not platinum. Catalyst comprises, at least, one metal oxide active in redox reactions for NO2 reduction to NO in reaction with CO, hydrocarbons and/or carbon black present in exhaust gas. Proposed device comprises engine exhaust system provided with above described catalyst.
EFFECT: reduced emission.
