Exhaust Emission Control System
VEHICLES WITH CATALYTIC CONVERTERExhaust emissions (CO, HC, NOx) are controlled by a combination of engine modifications and PCM fuel control.
Modifications to the combustion chamber, intake manifold, camshaft and ignition system form the basic control system. Additional control devices include a catalytic converter and the oxygen sensors which monitor mixture control.
These systems have been integrated into a highly effective system which controls exhaust emissions while maintaining good driveability and fuel economy.
