Cold-start emission control and catalyst technologies
In response to pressure from government organizations in the US and Europe to reduce even further the already low hydrocarbon, carbon monoxide, and oxides of nitrogen emissions from light-duty vehicles, manufacturers and their suppliers are developing and evaluating novel ways to achieve these challenging emission standards. A significant part of the development resources within the emission control technology arena is focused on controlling emissions associated with the vehicle cold-start process. Hydrocarbon and CO emissions reach their highest levels within the first minute after a cold vehicle start. The papers presented here echo this trend by addressing the latest cold-start developments in pre-converters, electrically heated catalysts, microwave heated catalysts, hydrogen burners, hydrocarbon absorbers, and precious metal catalysts which have low temperature light-off capability. Performance improvements outside of the cold-start process are also an active area of technology development. In this subject field, contributions are included in this volume that address the latest catalyst chemistry improvements, substrate configurations, and improved manufacturing methods associated with both catalysts and substrates. Papers have been processed separately for inclusion on the data base.
