Catalytic Converter: Description and Operation
GENERAL DESCRIPTION
The three-way catalytic converter, together with the dosed loop air-fuel ratio control based on the oxygen sensor signal, oxidizes carbon monoxides (CO)
and hydrocarbons (HC) and 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.
