Research Interests:

Dr. Jim Parks is a staff scientist in the Fuels, Engines, and Emissions Research Center (FEERC) at ORNL. A broad range of catalyst studies are performed at FEERC for the primary interest of controlling emissions from transportation vehicles to improve the environment and reduce potential health impacts. Dr. Parks conducts research in FEERC’s engine dynamometer labs where advanced catalysts are studied in real engine exhaust. His research interests are focused on the application of novel catalytic technologies to fuel efficient engine systems.

Selected current research themes include:

• Characterizing synergies between catalysts and advanced diesel combustion modes such as PCCI (Premixed Charge Compression Ignition) for both lean NOx trap and urea-based selective catalytic reduction catalysts.
• Understanding the chemistry of regeneration of a lean NOx trap with in-cylinder diesel engine reductant production.
• Developing unique analytical tools for the measurement of exhaust chemistry during the operation of lean catalytic emission control devices.
• Studying intra-catalyst chemistry during operation on a diesel engine platform for comparison to bench flow reactor data for the purpose of developing simulations and models for catalytic control devices.
• Investigating the potential of forming and/or controlling Mobile Source Air Toxics and other unregulated potentially health affecting species from engine and emission control systems.
