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

Green Car Congress

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. Their paper is published in the International Journal of Engine Research. RCCI background.

Study finds E20 offers higher peak load capacity and thermal efficiency than gasoline in RCCI combustion

Green Car Congress

In the newly reported study, they examined in-cylinder fuel blending with port fuel injection of gasoline or E20 and early-cycle, direct injection of ultra-low sulfur diesel or B20. Both biofuels offered faster transient response to recover the CA50 to the steady-state CA50 value than gasoline or ultra-low sulfur diesel.
