Small methyl ketones are known to have high octane numbers, impressive knock resistance, and show low emissions of soot, NOx, and unburnt hydrocarbons. However, previous studies have focused on the analysis of smaller ketones and 3-pentanone, while t

Short-carbon-chain ketones are known for their high octane numbers, their knock resistance, and their low soot emission. However, studies on the combustion behavior of ketones, particularly in the low temperature regime, are sparse, and small ketones

With the aim to study potential cooperative effects in the low-temperature oxidation of dual-fuel combinations, we have investigated prototypical hydrocarbon (C5H12) / oxygenated (C2H6O) fuel mixtures by doping n-pentane with either dimethyl ether (D

In view of a desired transition from fossil fuels to sustainably produced biofuels that should contribute to a net reduction of CO 2 emissions, promising fuel candidates have been identified including 2-butanone (methyl ethyl ketone, MEK) that is qua

2-butanone (methyl ethyl ketone) is a recently identified high-octane, next-generation biofuel candidate, synthesized through microbiological pathways from biomass. Its high octane number (RON = 117), low boiling point (80 °C), and relatively high v

Recently the possibility of hot beta-scission pathways gained attention. These reactions give a shortcut during the important fuel consumption phase in combustion processes leading from H-atom abstraction directly to the beta-scission products withou
