300 CPSI Euro 3 Ceramic Honeycomb SCR Substrate | 2.7 g/cm³ Density, 1500°C Temperature
Automotive exhaust catalysts are engineered systems composed of four essential components that work together to efficiently convert harmful emissions into less toxic substances.
- Active Ingredients: Core catalytic elements including precious metals, non-precious metals, and rare earth-doped catalysts that drive chemical reactions to break down pollutants.
- Carriers: Structural foundation providing optimal surface area and pore structure, with honeycomb ceramic carriers offering superior mechanical strength and thermal stability.
- Coatings: Surface applications like gamma-alumina (γ-Al₂O₃) that maximize contact between exhaust gases and active ingredients.
- Additives: Performance enhancers such as rare earth oxides that improve thermal stability and extend service life.
