Methanol and ethanol are promising alternative SI engine fuels. Engine simulation tools could help to unlock the full potential of these fuels. Previous work by the current authors has focused on building submodels to predict the gas dynamics, combustion and knock occurrence in alcohol engines. Here, these building blocks are implemented in a quasi-dimensional engine simulation code, which is subsequently...
Methanol is a sustainable and versatile alternative fuel for spark-ignition engines and other combustion applications. To characterize the combustion behavior of this fuel, a good understanding of the factors affecting its turbulent burning velocity is required. This paper presents experimental values of the turbulent burning velocity of methanol-air mixtures obtained in a fan-stirred bomb, for u′=2–6m/s,...
The use of biomass-derived ethanol in spark-ignition engines is an interesting option to decarbonize transport and increase energy security. An engine cycle code valid for this fuel, could help to explore its full potential. Crucial building blocks to model the combustion in ethanol engines are the laminar burning velocity and flame thickness of the ethanol–air–residuals mixture at instantaneous cylinder...
