The catalytic converter is a device that purifies exhaust gases discharged from the engine exhaust pipe. It is an external purification technology. The generation of harmful gases in gasoline engines is inseparable from the fuel combustion process. Among them, the three pollutants that have the greatest impact on humans are CO, HC and NOx. The main function of the three-way catalytic converter is to remove the three harmful pollutants in the exhaust gas. Gases undergo oxidation and reduction reactions and become harmless gases. The catalyst of the three-way catalytic converter itself does not undergo chemical reactions. Its function is to speed up the chemical reactions of harmful substances.
