TL;DR: In this article, a fuel reactivity controlled compression ignition (RCCI) concept is demonstrated as a promising method to achieve high efficiency, which is demonstrated in a heavy-duty test engine over a range of loads.
Abstract: A fuel reactivity controlled compression ignition (RCCI) concept is demonstrated as a promising method to achieve high efficiency – clean combustion. Engine experiments were performed in a heavy-duty test engine over a range of loads. Additionally, RCCI engine experiments were compared to conventional diesel engine experiments. Detailed computational fluid dynamics modelling was then used to explain the experimentally observed trends. Specifically, it was found that RCCI combustion is capable of operating over a wide range of engine loads with near zero levels of NOx and soot, acceptable pressure rise rate and ringing intensity, and very high indicated efficiency. For example, a peak gross indicated efficiency of 56 per cent was observed at 9.3 bar indicated mean effective pressure and 1300 rev/min. The comparison between RCCI and conventional diesel showed a reduction in NOx by three orders of magnitude, a reduction in soot by a factor of six, and an increase in gross indicated efficiency of 16.4 per cen...

TL;DR: In this paper, the authors provided deep insights into the processes occurring during knocking combustion in spark ignition engines, and future research directions, such as turbulence-shock-reaction interaction theory, detonation suppression and utilization, and super-knock solutions, are also discussed, including use of exhaust gas recirculation (EGR), injection strategy, and the integration of a high tumble - high EGR-Atkinson/Miller cycle.
