A global air pollution has been increased, environmental organizations of each countries have made more strict regulation. In such a situation, the most effective way of reducing air pollutants which from automotive is Three-way catalytic converters (TWCs). It have been successfully used for the control and the suppression of automotive emissions by converting basic air pollutants like CO, CxHy and NOx to their inactive products CO2, N2 and H2O. EPA required a verification of their TWCs with an enforced emission regulation. A purpose of EPA and other durability test is to verify the after treatment system"s function during warranty period. A car manufacturer must qualify the durability test of exhaust gas after treatment system. Consequently, the durability test is one of important certification course when a car manufacturer developing a new car. The main object of this research is to comprehend by demonstrating the EPA durability procedure. This experimental data will be used to investigate the thermal ageing characteristics of The EPA durability procedure.
