FIELD: engines and pumps.
SUBSTANCE: invention relates to diesel exhaust gas cleaning system. This system comprises selective catalytic recovery device and diesel carbon-black filter coated at least partially with catalytic layer. Said filter is arranged downstream of said selective catalytic recovery device. The catalytic oxidation device is arranged upstream of said selective catalytic recovery device and/or between said selective catalytic recovery device and carbon-black filter. Device to inject controlled amount of reducing agent is arranged at selective catalytic recovery device inlet. Device to inject controlled amount of hydrocarbons is arranged ahead of catalytic oxidation.
EFFECT: efficient cleaning and recovery.
