As lubricants petrodiesel, rapeseed methyl ester biodiesel and a mixture thereof were used. In the application-oriented test setup wear was considerably reduced and a low friction coefficient of 0.04 was achieved. Impurities of monoglycerides are assumed to be the cause for the friction-modifying effect.enBiodieselDiesel pumpDLCGMOta-Cultra-low friction621671journal article
