Catalytic Converter

Proper emission control is accomplished with a special 3-way catalytic converter which converts all 3 major pollutants (HC, CO and NOx). The converter is a dual-bed converter. The "upstream" section of the converter contains a reducing/oxidizing bed to reduce NOx while at the same time oxidizing HC and CO. An air supply pipe from the AIR or PAIR system introduces an extra amount of air between the dual beds (during closed loop mode), so second bed can oxidize any remaining HC and CO with a high conversion efficiency to minimize overall emissions.
