FIELD: transport.
SUBSTANCE: device (2) for vehicle (4) exhaust gases (20) aftertreatment by means of liquid reducing agent (18) delivery to exhaust gases (20) in exhaust pipe (32). The device (2) can locally heat surface (31) inside exhaust pipe with the help of Peltier element (6) using heating energy of exhaust gases (20) to evaporate liquid reducing agent (18) which reaches surface (31) and thus to prevent formation of reducing agent deposits inside exhaust pipe (32). Proposed invention also relates to method of vehicle exhaust gas aftertreatment using device (2) containing Peltier element (6).
EFFECT: higher speed of injected reducer evaporation and providing device operation at low temperatures of exhaust gases.
