Changes of engine oil flow properties during its life cycle

Original language description

The work is focused on quantification of influence of operation on flow properties of motorcycle engine oil. Three diff erent kinds of synthetic engine oil (MOTUL) were tested, namely unused oil, run-in oil (650 km after engine reboring) and regular engine oil (6200 km of motorcycle operation). The samples were frozen to below zero temperatures and kinematic viscosity was continuously monitored in the range of minus 5 °C and +115 °C. Consequently, the kinematic viscosity at reference temperatures of 0,40 and 100 °C was compared. Viscosity was measured by digital viscometer with concentric cylinders measuring geometry. The biggest diff erence occurred in case of lower temperatures where e.g. at 0 °C decrease to 29 % and 43 % of its original value was detected for used oil and run-in oil respectively. Flow behavior was modeled using several mathematical models --Arrhenius equation, exponential, and Gaussian equation. The best match between experimental and computed data was received in
