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

Green Car Congress

JANUARY 5, 2015

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.

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.
