William Pitz

Chemical Sciences Division's William Pitz's research on the combustion kinetics of homogeneous charge compression ignition (HCCI) and diesel fuels earned the top score (out of more than 50 projects) in the 2010 DOE Vehicle Technologies Program Annual Merit Review. The goal of Pitz's work is to provide accurate, fundamental kinetic mechanisms for combustion models that are used as tools to improve fuel efficiency and reduce emissions of vehicles.

The Advanced Combustion Engine subprogram of the Department of Energy's Vehicle Technologies Program is improving the fuel economy of passenger and commercial vehicles by increasing the efficiency of the engines that power them.

Work is performed in collaboration with industry, national laboratories, and universities, as well as in conjunction with the FreedomCAR and Fuels Partnership for passenger vehicle applications and the 21st Century Truck Partnership for commercial vehicle applications.

Research and development efforts focus on improving engine efficiency while meeting future federal and state emissions regulations through a combination of: combustion technologies that minimize in-cylinder formation of emissions; after-treatment technologies that further reduce exhaust emissions; and understanding fuel property impacts on combustion and emissions. Technologies that improve the overall engine performance are also pursued.
