Abstract Combustion chemistry models have been developed with inherent uncertainties in them. Whether a model that is developed using fundamental combustion experiments is capable to reproduce practical combustion processes within typical levels of measurement uncertainty is an open question. This paper quantifies the uncertainty of engine autoignition simulation using the uncertainties in the selected chemical kinetic model and then minimizes the model prediction uncertainty using various exper...

Abstract This paper investigates the impact of ethanol on the oxidation of iso-octane at low and intermediate temperatures. Flow reactor experiments are conducted on binary mixtures ranging from neat iso-octane to neat ethanol at temperatures of 650 K and 875 K, a pressure of 10 bar and an equivalence ratio of 0.058, with the intermediate species and gas temperatures measured along the reactor. At 650 K, where neat iso-octane is near the peak of its low temperature chain branching, the addition ...

Abstract This work develops a surrogate fuel that reproduces the octane blending of a market gasoline with ethanol. It first extends our previous investigation that reported strong, non-linear blending for ethanol/paraffin and ethanol/aromatic mixtures (Foong et al., Fuel 2014 p. 727) to consider mixtures of ethanol/cycloparaffin, ethanol/olefin, and hydrocarbons from different groups. On the molar basis, ethanol blends synergistically with cyclohexane and 1-hexene, whereas toluene blends antago...

Abstract This paper presents a study of the oxidation of iso-octane, ethanol, toluene and their mixtures in a pressurised turbulent flow reactor operating at 900–930 K, 10 bar, and an equivalence ratio of 0.058. A large set of fuels is investigated, including neat iso-octane, ethanol, toluene, their binary mixtures, gasoline reference fuels (PRF91 and TRF91), and their mixtures with ethanol. The resulting species are measured along the length of the reactor and simulated using existing kinetic m...

Abstract This paper studies the oxidation of n-heptane, iso-octane, ethanol and their mixtures in a pressurized flow reactor, with a focus on the potential relation between the fuels oxidation reactivity and their octane ratings. The flow reactor experiments are conducted at 550–900 K, 10 bar and an equivalence ratio of 0.058. Carbon monoxide is measured as an indicator of the global reactivity. Evident low temperature oxidation and negative temperature coefficient (NTC) behaviors are observed f...

Abstract Nitric oxide (NO) is a trace species that is always present in reciprocating engines, and can significantly affect fuel autoignition. This work presents a systematic investigation of the impact of NO on fuel autoignition in a standard, octane rating engine. Knock onset timing is investigated over a wide range of equivalence ratios, intake temperatures, and fuel compositions with increasing levels of NO added via the engine intake. NO is observed to both promote and retard autoignition i...

Abstract This paper investigates the impact of nitric oxide (NO) on n-heptane ignition in a rapid compression machine (RCM). The ignition delays of stoichiometric mixtures of n-heptane and varying amounts of NO (0–400 ppm) are measured in an argon diluent at 9 bar and over 650–1000 K. In the low temperature oxidation regime (≤ 720 K), ignition of n-heptane was promoted by NO up to 100 ppm, whilst higher NO levels do not further promote ignition. Stronger promoting effects are observed in the neg...
