Catalytic Converter: Description and Operation

GENERAL DESCRIPTION (CATALYTIC CONVERTER)

The three way catalytic converter, together with the closed loop air-fuel ratio control based on the oxygen sensor signal, oxidizes carbon monoxides
(CO) and hydrocarbons (HC), also reduces nitrogen oxides (NOx).

When the mixture is controlled at stoichiometric air fuel ratio, the three way catalytic converter provides the highest purification against the three
constituents, namely, CO, HC and NOx.
