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