Development Status of Metal Substrate Catalysts

摘要

Driven by stricter emissions limits, the effectiveness of catalyst systems must be increased continually. Metal catalyst substrates offer a variety of solutions for all combustion engine applications: 1. Metal substrate technologies are available for both spark ignition and Diesel engines 2. All emissions (HC, CO, NO_x, PM) can be significantly reduced 3. New developments like the cone-shaped catalyst and the open particulate traps help to meet future emissions legislation 4. New, high cell density, ultra thin foil substrates further increase catalyst efficiency 5. Stress and durability of metal substrates can be precalculated using detailed FEM models before component or engine tests
