FIELD: engines and pumps.
SUBSTANCE: invention relates to exhaust gas postprocessing system. Claimed system (10) comprises the components that follow. Catalytic neutraliser unit (12) with at least one catalytic material (14) arranged in exhaust gas pipe (16) downstream of ICE (18). First tank (44a) stores at least one reducing agent (22) while second tank (44) contains the activating agent and one or several dispensers (20, 20a, 20b) to feed at least one reducing agent (22) to reduce the content of NOX oxides in exhaust gases (24) including at lest one hydrocarbon. Said tanks are meant for feed of at least one activating material (26) into exhaust gases (24). Said material (26) includes at least one ether-type oxygen-bearing hydrocarbon selected from the group consisting of triglyme, diglyme, monoglyme, diethyl ether and dipropyl ether. It ups the catalytic activity of catalytic material (14) as compared with its catalytic activity without activating material (26) in at least the preset temperature range. This invention discloses the process of exhaust gas (24) processing in the postprocessing system (10) and vehicle (40) with such system.
EFFECT: higher catalytic activity, lower costs and reducing agent consumption.
