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. Rolf Reitz.

USDA and DOE select 13 biofuels projects for more than $41M in awards

Green Car Congress

Five projects newly selected will help to replace the need for gasoline and diesel in vehicles. This project will optimize rapeseed/canola, mustard and camelina oilseed crops for oil quality and yield using recombinant inbred lines. The oils will be hydrotreated to produce diesel and jet fuel.
