TWC catalyst three way catalysts with ceramic substrate for
catalytic converters
Product Description
- Introduction
Our company specializes in manufacturing a comprehensive range of
automotive three-way catalytic converters (TWCs). These catalysts
feature either ceramic honeycomb substrates (cordierite monoliths)
or metal honeycomb substrates (constructed with stainless steel
casings and Fe-Cr-Al honeycomb cores). The substrate surface is
coated with a high-surface-area, thermally stable washcoat
integrated with precious metals including platinum (Pt), palladium
(Pd), and rhodium (Rh).
As exhaust gases from internal combustion engines pass through the
catalyst, harmful hydrocarbons (HC), carbon monoxide (CO), and
nitrogen oxides (NOx) are efficiently converted into harmless
carbon dioxide (CO₂), water (H₂O), and nitrogen (N₂), achieving
superior emission purification. Our TWCs are compatible with all
vehicle types and meet stringent emission standards such as Euro 2,
Euro 3, Euro 4, Euro 5, Euro 6, EPA, and CARB.
