FIELD: engines and pumps.
SUBSTANCE: cylinders of engine running on lean mixes are proposed to be divided into two groups to discharge waste gases via pipelines assigned to each said group. Each said pipeline incorporates carbon-black filter. Said exhaust pipelines are integrated into one common exhaust pipeline at its inlet. Said common exhaust pipeline accommodates catalyst for nitrogen dioxide removal. Said filters are regenerated to limit waste gas temperature in common exhaust pipeline by mean temperature of waste gases in operating conditions and at filter recovery to protect aforesaid catalyst from thermal damages.
EFFECT: higher efficiency.
