Abstract Derived Cetane Numbers (DCNs) of engine lubricating oil/multicomponent 95 Research Octane Number (RON) gasoline surrogate mixtures were measured in an Ignition Quality Tester (IQT). Measurements separately assess the effects of calcium- and magnesium-based detergent additive fraction, oil viscosity, oil degradation, and base oil classification on mixture ignition propensity at conditions with relevance to low speed pre-ignition (LSPI) in gasoline engines. Testing of 0–25% (by mass) oil ...

Abstract Many studies of the flame speed of hydrocarbon and oxygenated fuels show that flame speed is very sensitive to formyl radical (HCO) reactions with small species, such as HCO + M = H + CO + M (R 1 ), HCO + O 2 = HO 2 + CO (R 2 ) and HCO + X = CO + XH (X = H, OH) (R 3 ). Through comparison among experimental measurements and kinetic model predictions, this paper investigates CH 2 O flame speed sensitivities to the effects of HCO prompt dissociation and CO 2 third-body participation in R 1...

Abstract The global chemical character of complex chemical fuel mixtures is explicitly determined by evaluating the abundances of chemical functional groups present within them rather than by applying a traditional interpretation based upon molecular species composition. Statistical analyses of the relationships among each chemical functional group and specific combustion property targets (CPTs) of the fuel are rigorously developed. The results demonstrate that the four CPTs currently used in av...

The reactivity-promoting effect of trace nitrogen oxides (NOx) on post-induction oxidation of a synthetic natural gas (2% ethane in methane) has been experimentally studied in a high-pressure laminar flow reactor (HPLFR) at 10 ± 0.1 atm, nominal reaction temperature of 818 ± 5 K, and several equivalence ratios (φ ∼ 0.5, 1.0, and 2.0). Each set of experimental measurements was simulated using several literature C0–C2 + NOx kinetic models, both recent and legacy, using approaches shown to lead to ...
