Catalytic Converter

Proper emission control is accomplished with the special three-way catalytic converter which converts all 3 major pollutants (HC, CO and NOx). In order for this catalytic converter to be effective, precise control of the oxygen content of gases entering the converter is necessary, thus the need for the oxygen sensor, ECM and special carburetor.
