Influence of Oxymethylene Ethers (OMEn) in Mixtures with a Diesel Surrogate

Within this work the effects of blending oxymethylene ethers (OMEn) to a diesel surrogate (50 mol% n-dodecane, 30 farnesane, and 20 1-methylnaphthalene) were investigated by performing two different types experiments: measurements sooting propensity laminar burning velocity, each in premixed flames. For propensity, OME3, OME4, OME5 considered as compounds—each mass fractions 10%, 20%, 30%. The was found depend strongly on OMEn grade but not its chain length. In addition, effect velocity studied for OME4 admixture 30% with first time. This lead increased velocities; however, much less than might be foreseen when considering respective values neat fuels.
