Combustion of high carbon (C7-C8) alcohol fuels in a reactivity controlled compression ignition (RCCI) engine as low reactivity fuels and ANN approach to predict RCCI emissions

Fuel, 2022
High carbon alcohol fuels such as heptanol (C7) and octanol (C8) have recently attracted attention among alternative fuels due to their high oxygen content, cetane number and energy density and their production using sustainable pathways in comparison to other common alcohols.
