Catalytic Converter

Proper emission control is accomplished with the special catalytic converter used with the CEC system. All models use a dual bed monolithic-type converter with "downstream" air injection. The injection of air between the 2 beds allows more complete oxidation of HC and CO in the closed loop mode. In order for these converters to be effective, precise control of the oxygen content of exhaust gases entering the converter is necessary; thus the need for the oxygen sensor, MCU and feedback carburetor.
