Development of a Reduced Methane-Hydrogen-Polyoxymethylene Dimethyl Ether Mechanism under Engine-Relevant Conditions.

ABSTRACT: Polyoxymethylene dimethyl ethers (PODE _n ) have a high cetane number and a high oxygen content, which can effectively reduce the soot emission. In this study, PODE₃, methane, and hydrogen were used as the characterization fuel. First, the detailed reaction mechanism of PODE₃ and GRI-Mech 3.0 was reduced under engine-relevant conditions by using the reduced methods of the direct relation graph, the directed relation graph with error propagation, the sensitivity analysis, and the reaction pathway analysis. Then, the simplified PODE₃ and methane-hydrogen mechanism were coupled and optimized. Finally, the simplified chemical kinetics mechanism of methane-hydrogen-PODE₃ (67 species, 260 reactions) was developed. After that, the metha
