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

RCCI is a dual-fuel combustion technology developed by Dr. Rolf Reitz and colleagues at the University of Wisconsin-Madison Engine Research Center laboratories. The process involves introduction of a low reactivity fuel into the cylinder to create a well-mixed charge of low reactivity fuel, air and recirculated exhaust gases.

UW-Madison engineer collaborating with entrepreneur on 6-cycle, external combustion engine; could be up to 30% more efficient than standard diesel

Green Car Congress

As an external combustion engine, it can be powered by a wide range of liquid and gaseous fuels. The K6 engine uses six strokes instead of four to reduce the pressure of exhaust gases, which allows it to harvest more energy rather than expelling it with the gas. —Timothy Shedd.
