Three-Way Catalytic Converter Manufacturer

We manufacture three-way catalytic converters for distributors, wholesalers, exhaust suppliers and automotive businesses. Custom designs, substrates, catalyst formulations and production volumes are available for different vehicle applications and emission requirements.

Що таке трикомпонентний каталітичний нейтралізатор?

  • A three-way catalytic converter (TWC) is an emission control device primarily used in gasoline vehicles. It helps reduce three major pollutants in engine exhaust: nitrogen oxides (NOx), carbon monoxide (CO), and hydrocarbons (HC).
  • Inside the converter, exhaust gases pass through a catalyst-coated substrate containing precious metals such as platinum (Pt), palladium (Pd), and rhodium (Rh). These catalysts promote oxidation and reduction reactions, converting harmful pollutants into less harmful gases.
  • NOx → N₂ + O₂    CO → CO₂       HC → CO₂ + H₂O (This three-pollutant conversion capability is why it is called a three-way catalytic converter.)

How Does a Three-Way Catalytic Converter Work?

As exhaust gases pass through the catalyst-coated substrate, oxidation and reduction reactions help convert NOx, CO and HC into less harmful substances.

01

Engine Exhaust

NOx + CO + HC

Harmful pollutants enter with the engine exhaust.

02

Catalyst-Coated Substrate

Pt / Pd / Rh

Provides a large surface area for catalytic reactions.

03

Catalytic Reactions

Oxidation + Reduction

Converts harmful pollutants into less harmful substances.

04

Cleaner Exhaust

Reduced NOx, CO & HC

Targeted pollutants are reduced before exhaust release.
