 scientist and inventor.

Nicknamed the "father of catalytic combustion," he invented the original catalytic combustor for gas turbine engines in the early 1970s. Gas turbines work by mixing fuel with compressed and heated air, which burns and generates energy to turn the turbines. Unfortunately, nitrogen oxide gases, which contribute to global warming, are emitted during this process. Dr. Pfefferle developed a process that uses a catalyst (a substance used to speed up a chemical reaction) to allow combustion without the significant formation of nitrogen oxides and carbon monoxide.

After 20 years with Engelhard Industries, he became co-founder of Precision Combustion in North Haven, CT in 1986. He continues to work as Principal Investigator. Dr. Pfefferle has dedicated his career to developing clean and efficient technologies for combustion engines. He has also invented the Microlith catalytic reactor for automobiles and fuel processing and the RCL catalytic combustor for ground-power gas turbine machines.
