Catalytic Converter

Proper emission control is accomplished with a 3-way catalytic converter that converts all 3 major pollutants (HC, CO and NOx) into carbon dioxide and water. 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, the ECM and the feedback carburetor.
