FIELD: engines.
SUBSTANCE: invention relates to catalytic product for processing exhaust emissions of diesel engine containing hydrocarbons, carbon monoxide and solid particles. Product contains a diesel oxidation catalyst and a carrier. Herewith the diesel oxidation catalyst contains the first layer of porous coating applied on the said carrier containing a high-melting metall-oxide substrate with highly developed surface, and platinum group metal component containing platinum (Pt) and palladium (Pd) on a high-melting metall-oxide substrate. First zeolite component has the ratio of silicon dioxide to aluminium oxide greater than 1000. Invention also discloses a system for processing exhaust gases of a diesel engine and a method of processing the flow of diesel exhaust gases.
EFFECT: invention allows minimizing the negative interactions of platinum group metals with zeolite.
