FIELD: engines and pumps.
SUBSTANCE: catalytic neutraliser used in internal combustion engine exhaust system. It comprises case with gas inlet and outlet and encased catalyst carrier. Catalyst carrier can be divided into multiple zones or sections partially separated to inhibit heat transfer. Said zones can be partially isolated by walls. Said walls can include isolation material to decrease heat escape radially outward. Every said zone defines, on the whole, a separate channel communicating said inlet and outlet.
EFFECT: accelerated heating at cold starting.
