This component consists of an outside steel shell and inside ceramic element 
coated with noble metals of Pt, Pd, Rh. When the exhaust is passing through the 
three-way catalytic converter CO, HC, and NOx the activity of gas is enhanced. 
Under such a high temperature, the CO would be oxidized into a gas without 
color and poison, CO2; meanwhile the HC compound is turned into H2O and CO2;
finally the NOx is deoxidized into nitrogen. The three gases are turned into 
the non-toxic gas to purify exhaust.
