Reducing motor oil dilution in internal combustion engine driven by fatty acid ester with bivalent and polyvalent alcohols, fatty alcohols or oxygen functionalized long chain hydrocarbons, involves introducing motor oil

摘要

Motor oil dilution reduction involves introducing motor oil directly or as a component of the fuel with additives. The additive is selected from branched or unbranched monoalcohol containing 3-10C and their esters with 1-5C fatty acids, branched or unbranched mono esters of diols containing 3-10C with 1-5C fatty acids, alkyl ketones with 3-12C, alkyl ethers with 3-12C, alkyl amines with 3-12C or their mixture. An independent claim is included for a material composition for reducing motor oil dilution in internal combustion engine.
