An analytical approximation for low- and high-temperature autoignition for dimethyl ether–air mixtures

Dimethyl ether has proven to be one of the most attractive alternatives to traditional fossil oil derived fuels for compression ignition engines. In this study, a skeletal mechanism consisting of 32 species and 49 elementary reactions, based on the detailed mechanism proposed by Fischer et al. [Int. J. Chem. Kinet. 32 (12) (2000) 713–740], is further reduced to a short 36-step mechanism describing first and second stage ignition as well as the...
