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.

Bombardier introduces new, more efficient and cleaner Evinrude outboards

Green Car Congress

Using advanced computational fluid dynamics software developed by the University of Wisconsin, BRP crafted the entire engine around the moment of combustion and developed the first outboard engine block designed specifically for direct-injection technology. This combined with the new alloy, increase the piston strength and durability.

Light duty RCCI can deliver engine-out Tier 2 Bin 5 NOx; potential for 52% gross indicated efficiency

Green Car Congress

Rolf Reitz of the University of Wisconsin found that reactivity controlled compression ignition (RCCI) ( earlier post ) in a light-duty engine can meet Tier 2 Bin 5 NO x levels without aftertreatment, while offering a 4% improvement in fuel consumption and 7.3% Sage L Kokjohn and Rolf D.

Achates Power wins $9M from ARPA-E to develop gasoline compression ignition medium-duty multi-cylinder opposed-piston engine

Green Car Congress

The unthrottled nature of the compression ignition process provides high engine efficiency while achieving compliant exhaust emissions with conventional, low-cost aftertreatment. This—in addition to the opposed engine architecture—could increase fuel efficiency by 40-50% over the comparable spark-ignited gasoline engine, Achates said.
