Reactivity Controlled Compression Ignition (RCCI) for high-efficiency clean IC engines

Reactivity Controlled Compression Ignition (RCCI) is a new internal combustion engine concept that has been demonstrated to be a promising method to achieve high efficiency – clean combustion. RCCI engine experiments performed at the Engine Research Center in light- and heavy-duty test engines and in a vehicle have also been compared to conventional diesel engine experiments. In addition, detailed compu- tational fluid dynamics modelling is used to explain the experimentally observed trends. It has been found that RCCI combustion is capable of operating over a wide range of engine loads with near zero levels of NOx and soot pollutant emissions, acceptable pressure rise rates and ringing intensities, and very high indicated efficiencies. 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 in a heavy-duty test engine. Comparison between RCCI and conventional diesel show 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%. The simulation results indicate that the improvement in fuel conversion efficiency is due both to reductions in heat transfer losses and improved control over the start and end of combustion.
