Studies in Surface Science and Catalysis | 1999

The use of catalysts with ambient temperature activity for the control of cold-start automotive emissions

David Scott Lafyatis; Todd Howard Ballinger; Gregg S. Lammey; Jonathan Charles Frost; Barry John Cooper

Abstract A combination of engine management and catalyst technology has been utilized to greatly reduce HC emissions from a 1994 production vehicle. The key to the catalyst technology is its activity for CO and H2 oxidation at ambient temperature, allowing excellent pollutant control from a cold start.
