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. The E-TEC incorporates pistons made from a new alloy originally developed by NASA.

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.

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

The dual-fuel PCCI strategy showed thermal efficiency of 53%. Emissions under the dual-fuel concept, at 11 bar IMEP. The University of Wisconsin concept proposes the use of dual fuel tanks, with port fuel injection of gasoline and direct injection of diesel, with the in-cylinder mixing of the fuels.
