EXHAUST SYSTEM
CATALYTIC CONVERTER
The purpose of the catalytic converter is to convert the three pollutants of carbon monoxide (CO), hydrocarbons (HC)
and oxides of nitrogen (NOx) contained in the exhaust of gasoline engines, into the harmless compounds of water
(H2O), carbon dioxide (CO2) and nitrogen (N2).
The catalytic converter contains a catalyst, a word coming from the Greek and which designates the element essential
for catalyst which triggers chemical reactions without itself being consumed.
These catalysts in the 3--way catalytic converter are the rare metals platinum (Pt) and rhodium (Rh).
The catalytic converter consists essentially of three main elements. The exhaust gases flow through the catalytic con-
verter and, in so doing, coming into contact with rare metals (Pt and Rh).
The following chemical reaction are produced.
CO + O2 → CO2
HC + O2 → CO2 + H2O
NOx → N2 + O2
