Abstract

In this paper, the author uses DME as an additive to methanol diesel, and uses AVL-Fire software to make a simulation analysis to mixed fuel. In the analysis, the mass ratio is fixed by a methanol content of 12% unchanged. The content of diesel oil are respectively 70%, 60%, 50%, and 40%, and the rest is DME. Under 2200r/min high load conditions, the author analyzes the combustion process and emission of these four mixed fuels, and compares them with diesel. The results show that: with lowers levels of diesel, the cylinder pressure gradually decreases, the pressure peak where the crank angle is essentially the same, the heat release gradually increases; with the reducing content of diesel, the emissions of NOx increase, while the Soot emissions reduce.
