TWC Catalyst for Gasoline Engines (Platinum-Palladium): Reduces Gasoline Sulfur
TWC Three-Way Catalyst With Metal Shell For Gasoline Engine
Product Description
1. Introuduction
he three-way catalytic converter stands as the most critical external purification component in a car’s exhaust system. Its core function? Converting harmful automotive emissions—like carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx)—into harmless substances through oxidation and reduction reactions.
Here’s how it works: When high-temperature exhaust gas flows through the converter, the built-in catalyst (typically containing platinum, palladium, or rhodium) boosts the reactivity of CO, HC, and NOx. This triggers key chemical reactions:
- CO (carbon monoxide) is oxidized at high temperatures into colorless, non-toxic carbon dioxide (CO₂).
- HC (hydrocarbons) are broken down via oxidation into water (H₂O) and carbon dioxide.
- NOx (nitrogen oxides) undergo reduction, transforming into nitrogen (N₂) and oxygen (O₂)—gases naturally found in air.
By neutralizing these three primary pollutants, the three-way catalytic converter plays an irreplaceable role in purifying vehicle exhaust, making it a cornerstone of modern automotive emission control systems.
