Abstract
A skeletal reaction mechanism was constructed including three saturated furan biofuels such as tetrahydrofuran(THF), 2-methyltetrahydrofuran(2-MTHF) and 2-butyltetrahydrofuran(2-BTHF). The mechanism contained 133 species and 582 reactions. In addition, the chemical reaction processes of polycyclic aromatic hydrocarbon(PAH) formation, growing to pyrene(A4) and soot formation were described. The experimental data of ignition delay, laminar flame velocity, and molar concentration of species for different sub-mechanisms were further compared with the simulated results under the wider operating conditions. The results showed that the mechanism could reproduce the combustion characteristics of fuel. In addition, the effect of blending diesel with furan fuels on the soot emissions was investigated on a gasoline-diesel RCCI engine. The results showed that blending saturated furan biofuel could mitigate the formation of engine soot emission. Consequently, the mechanism reliability for soot emission prediction was verified.
