1-Methylnaphthalene (1-MN), also known as α-methylnaphthalene, is a substituted diaromatic hydrocarbon that is widely used as one of the representative aromatic hydrocarbons in surrogate fuels of diesel. The ignition characteristics of 1-MN have been investigated in the present study using a rapid compression machine (RCM) at compressed pressures of P_C = 15–40 bar, low-to-intermediate compressed temperatures of T_C = 837–980 K, and varying equivalence ratios of ϕ = 0.5, 1.0, and 1.5 in air. The current RCM ignition delay measurements were found to complement the existing shock tube ignition delay data in the literature. The performance of two of the latest literature chemical kinetic models in estimating the ignition characteristics of 1-MN has been assessed and discussed. In addition, reaction path analyses and brute force sensitivity analyses have been conducted to identify the important oxidation pathways of 1-MN described by the two literature models. Based on the results from these chemical kinetic analyses, the improvements to the 1-MN model are suggested and discussed.
