FIELD: technological processes.
SUBSTANCE: invention discloses methods and systems for operation of engine exhaust gas neutralization system for increasing efficiency of catalytic neutralizer of exhaust gases of body base and reducing engine emissions. In one of the examples, the bypass channel can be connected to the main outlet channel and, in conditions, which can negatively affect the functionality of the catalyst base body neutraliser, exhaust gases can be rationally directed through the bypass channel, bypassing the catalytic neutralizer of the body base.
EFFECT: heat of exhaust gases can be recuperated by means of heat exchanger connected with bypass channel, and heat can be used for engine heating and passenger compartment heating.
