2-methyltetrahydrofuran (MTHF2) has been recently regarded as a promising alternative engine fuel. However, the chemical reaction mechanism for MTHF2 combustion in not reported to date. In this study, reduced diesel/MTHF2 with only 78 species among 233 reactions was constructed dual-fuel simulations. Firstly, diesel surrogate involving sub-mechanisms of n-decane, iso-octane, methylcyclohexane (...
