Insights into the oxidation kinetics of a cetane improver – 1,2-dimethoxyethane (1,2-DME) with experimental and modeling methods

A kinetic investigation was carried out in this work for an oxygenated fuel additive, 1,2-dimethoxyethane (1,2-DME) to reveal the oxidation chemistry responsible for its practical function as a cetane improver. Experiments were conducted for 1,2-DME/O2/N2 mixtures with different equivalence ratios (0.5, 1.0 and 2.0) in a high-pressure (10 atm) jet-stirred reactor (JSR) facility over the temperature range of 450–1100 K.
