Abstract

An oxidation mechanism of dimethyl ether (DME) low-temperature autoignition was examined. The mechanism comprised of three main steps, chain initiation, followed by chain propagation, and then chain branching. The kinetics of DME autoignition was found to be a complex mechanism . It was found that the change in kinetics was influenced by the factors like temperature, pressure, and relative concentrations.
