Alternative eco-friendly lubes for clean two-stroke engines

摘要

High performance lubricant for clean two-stroke engines operating with ethanol-containing fuels was developed by the selection of the optimal synthetic esters base oil followed by an improvement of the additives composition. The developed lubricant has very good wear resistance, ashless and low carbon soot deposit formation. The lubricant has low toxicity for aqueous organisms (algae and Daphnia Magna) and high biodegradability. Good wear resistance and low friction were achieved because of formation of a protective transparent friction lacquer on the contact surface due to tribochemical reactions.
