Diesel Emission Control: 2001 in Review

The paper covers reported developments from all major conferences in the year 2001 that occurred in the US and Europe and gives a comprehensive overview of the current state-of-the-art in diesel emission control.

The latest developments on nature of diesel particulates are summarized. The variety of diesel particulate filter regeneration strategies that will become so important to filter application are reviewed. Filter retrofit and durability issues are addressed. DeNOx catalysts, SCR, NOx traps for diesel, and non-thermal plasma methods are summarized. Integrated NOx/PM systems are described. NOx efficiency and fuel penalty costs for various NOx systems are summarized, as are the published capital costs of some key systems.
