Three-Way CatalyticConverter conversion principle

- Aug 08, 2018-

Three-Way CatalyticConverter is used to limit the amount of pollutants such as HC, Co and NOx in the exhaust gas.

The Three-Way CatalyticConverter is located on the exhaust duct between the exhaust manifold and the muffler. Its role is to convert harmful substances (CO, NOX, HC) in the exhaust into harmless substances.

Three-Way CatalyticConverter conversion principle

The core of TWC is a honeycomb aluminum frame, and catalytic converters such as platinum, rhodium and palladium are deposited on the aluminum frame. Among them, platinum and palladium are catalyzed by oxidation, and ruthenium is a catalytic effect of reduction.


◆: H4C2+3O2 → 2CO2+2H2O

◆:NOX+CO → N2+CO2

Repose cites Germany's exhaust pipe modification concept and technology, keeps improving its own brand, strictly controls every link when modifying the exhaust pipe, and gives a full explanation of the questions raised by the owner.
