FIELD: engines and pumps.
SUBSTANCE: exhaust gas cleaning system comprises a reagent injection nozzle (3) in front of catalyst (1) for nitrogen oxides selective reduction. Nozzle (3) is disposed on an angle tube (4) inside sleeve (5) mounted on perforated support rings (6) and (7) in exhaust gas pipeline (2). Opposite to openings (8) of support ring (6) located at the entrance to sleeve (5), flap valves (9) are mounted.
EFFECT: ensuring the capture by the exhaust gases flow passing through the sleeve of all reagent sprayed in the sleeve when the engine is running in different modes.
