Components of coating Catalytic Converters:
Aluminium Oxide
- Increase of surface area by a factor of approx. 10,000
- High precious metal dispersion
- Durability (temperature as well as poison resistance)
Cerium Oxide:
- Oxygen storage and release under cycling exhaust conditions
- Lambda – Window
Zirconium Oxide/Promoters:
- Increase of temperatures stability
- Catalytic active Precious Metals (Pt, Pd, Rh)
- Substrate/ Monolith
- Cordierite/ Metal
- Volume/ CPSI/ Wall thickness
