Temperature dependent kinematic viscosity of different types of engine oil

Popis výsledku v původním jazyce

The objective of this study is to measure how the viscosity of engine oil changes with temperature. Six different commercially distributed engine oils (primarily intended for motorcycle engines) of 10W--40 viscosity grade have been evaluated. Four of theoils were of synthetic type, two of semi--synthetic type. All oils have been assumed to be Newtonian fluids, thus flow curves have not been determined. Oils have been cooled to below zero temperatures and under controlled temperature regulation, kinematic viscosity (mm2/s) have been measured in the range of --5 °C and +115 °C. Anton Paar digital viscometer with concentric cylinders geometry has been used. In accordance with expected behavior, kinematic viscosity of all oils was decreasing with increasing temperature. Viscosity was found to be independent on oil's density. Temperature dependence has been modeled using several mathematical models -- Vogel equation, Arrhenius equation, polynomial, and Gaussian equation. The best match bet
