Kia Cadenza YG: Exhaust Emission Control System / Description and Operation
Exhaust emissions (CO, HC, NOx) are controlled by a
combination of engine modifications and the addition of special control
components.
Modifications to the combustion chamber, intake manifold, camshaft and ignition system form the basic control system.
These items have been integrated into a highly effective
system which controls exhaust emissions while maintaining good
drivability and fuel economy.
Description
The catalytic converter of the gasoline engine is a three way
catalyst. It oxidizes carbon monoxide and hydrocarbons (HC), and
separates oxygen from the oxides of nitrogen (NOx).
