Sooting characteristics of polyoxymethylene dimethyl ether blends with diesel in a diffusion flame

In this paper, we investigate the sooting propensity of PODEn/diesel blends. The sooting characteristics of PODEn/diesel blends are determined using a standard ASTMD1322 smoke point lamp. The performance of PODEn with different chain length (addition of –CH2O– units) is benchmarked against other oxygenated soot suppression additives, including esters (methyl butyrate), carbonates (dimethyl carbonate) and alcohols (n-butanol). Soot reduction...
