Biodiesel contains large Me esters including Me palmitate (MP), Me oleate (MO), Me linoleate (ML), etc. Long alkyl chains and asym. structures of these large Me esters lead to complexity in development of kinetic models. In this paper, surrogate fuels for large Me esters were proposed and developed. Surrogate models can be used to replace the detailed mechanisms of large Me esters in prediction of oxidation and autoignition properties. Key characteristics in combustion have non-linear relationships with fuel components in a neural network diagram, which indicates that surrogates with the same functional groups can exhibit similar combustion properties as large Me esters. In formulation of surrogate fuels, candidates consist of small species such as Me decanoate, n-hexadecane, Me trans-3-hexenoate, and 1, 4-hexadiene. To compare the oxidation properties, point-to-point exptl. validations were conducted in laminar flow reactor. Oxidation properties of surrogate and target fuels were in satisfactory agreements. Surrogate fuels not only successfully captured the discrepancies in reactivity of different Me esters, but also reproduced species concentrations of intermediate and products at various equivalence ratios. To test the performance in predicting autoignition characteristics, simulations based on surrogate models were compared with previous exptl. data. Surrogate models not only predicted ignition delay times at various pressure and equivalence ratios, but also reproduced the trends of apparent activated energy under different conditions. To sum up, oxidation and autoignition characteristics of large Me esters can be predicted by the combined kinetic model of small mol. compounds, which will have great potentials in the development of kinetic models for fuels with complicated mol. structures.
