Exactly how does it function?
The catalytic converter works to reduce the emission of damaging gases such as carbon monoxide gas, nitrogen oxides as well as hydrocarbons. All the gases from the engine go through the converter as well as the muffler. As they pass across the ceramic beads a chemical reaction happens which changes the gases into water vapour and other safe gases. The oxidation catalysts convert the carbon monoxide as well as hydrocarbons right into carbon dioxide and also water, while the decrease catalysts transform nitrogen oxide right into its constituent parts of nitrogen as well as oxygen.
