University of Wisconsin Researchers Investigating Dual-Fuel (Gasoline and Diesel) Partially Premixed Combustion for High-Efficiency, Ultra-Low Emission Combustion; 53% Thermal Efficiency

Green Car Congress

Researchers at the University of Wisconsin, led by Dr. Rolf Reitz, are investigating a blended dual-fuel (gasoline and diesel) concept to extend the operating range of partially premixed charge compression ignition combustion by using the varying fuel reactivity of the charge blend, which is determined in real time.

ORNL study finds multi-mode RCCI can offer 15%+ fuel economy improvements across multiple light-duty driving cycles

Green Car Congress

Drive cycle fuel economy for PFI, CDC, and multi-mode RCCI operation. Among their findings were that multi-mode RCCI has the potential to offer greater than 15% fuel economy improvement over a 2009 gasoline PFI baseline over many light-duty driving cycles, despite the lack of complete drive cycle coverage for RCCI mode.
