Three-Way Catalyst (TWC)

Advanced Emission Control Solution for Gasoline Engines

Function & Application

The Three-Way Catalyst efficiently converts major gaseous pollutants in engine exhaust—including carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), and formaldehyde—into carbon dioxide (CO₂), water (H₂O), and nitrogen (N₂) through catalytic reactions. It significantly reduces harmful vehicle emissions and helps minimize their environmental impact.

Designed for Next-Generation Emission Standards

Engineered to meet Euro 7 and China 7 emission requirements.

Key Advantages

01 | Low Light-Off Temperature

Reaches its effective operating temperature rapidly and delivers high catalytic activity, enabling efficient pollutant conversion soon after engine start-up.

02 | High Oxygen Storage Capacity

Provides strong oxygen storage capacity and rapid oxygen storage and release, helping maintain stable catalytic efficiency under changing air-fuel conditions.

03 | Excellent Thermal Durability

Offers excellent resistance to high temperatures and minimizes performance degradation, supporting reliable operation and a long service life.
