SummaryTh e article is devoted to the study of cold fl ow properties of neat esters of branched chain alcohols with fatty acids and blends of these esters with fossil diesel fuel. According to the determined CFPP values the infl uence of alcohol branching on the fuel fi lterability is negligible and was detected only in the case of 2-ethyl hexanol. Fossil fuel blending with fatty esters up to 10 % vol. does not substantially change the cold fl ow properties of fossil fuel. DSC cooling scan parameters should be employed to predict CFPP of blended diesel fuel.
