چکیده انگلیسی
Unrefined biodiesels containing small quantities of monoglycerides, diglycerides, and triglycerides, and refined biodiesels not containing these glycerides were added to diesel fuel and the resulting lubricity was measured using the High Frequency Reciprocating Rig (HFRR) method. The unrefined biodiesels showed higher lubricity properties than refined biodiesels. The chemical factors influencing the lubricity properties of biodiesels were investigated. Methyl esters and monoglycerides are the main compositions that determine the lubricity of biodiesels that meet international standards. Free fatty acids and diglycerides can also affect the lubricity of biodiesel, but not so much as monoglycerides. Triglycerides almost have no effects on the lubricity of biodiesel.
