Cold Start Concept (CSC) Catalysts for Future Emission Regulations

摘要

1. Low temperature emission control is a major challenge (1) Control of cold-start emissions is crucial to meet the future stringent emission regulations (2) Fuel economy and GHG legislation lead to lower exhaust temperatures 2. Cold Start Concept (CSC) technologies not only improve low temperature storage functions but also enhance low temperature conversion functions (1) Gasoline Cold Start Concept (gCSC) catalysts combine low temperature TWCs and extruded zeolite substrates (2) Diesel Cold Start Concept (dCSC) catalysts integrate NO_x/HC storage/conversion and CO/NO_x conversion functions (3) Performance advantages demonstrated on vehicles/engines.
