The Miller Cycle and its benefits in terms of NOx emissions on diesel engines and power density on gas engines is likely to remain a dominant theme among engine developers. Likewise, the Atkinson Cycle offers improved fuel consumption benefits. To assist gas engine developers to exploit these techniques, researchers at the Swiss Federal Institute of Technology Zurich and Munich University of Technology set out to create realistic mathematical models.

1 Growing significance of methane as an engine fuel

Natural gas has gained significance in recent years due to its availability and its potential for emissions reduction while allowing a simultaneous increase in engine efficiency due to the high knocking resistance of methane. Lower combustion temperatures due to lean burn operation and Miller/Atkinson valve timing lead to a reduced tendency to combustion knock compared to operation under stoichiometric conditions. They hence allow higher compression ratios or boost pressures to the...
