    Low-temperature behaviour of the engine oil

  • Original language description

    The behaviour of engine oil is very important. In this paper has been evaluated temperature dependence kinematic viscosity of engine oils in the low temperatures. Five diff erent commercially distributed engine oils (primarily intended for automobile engines) with viscosity class 0W--40, 5W--40, 10W--40, 15W--40, and 20W--40 have been evaluated. The temperature dependence kinematic viscosity has been observed in the range of temperature from --15 °C to 15 °C (for all oils). Considerable temperature dependence kinematic viscosity was found and demonstrated in case of all samples, which is in accordance with theoretical assumptions and literature data. Mathematical models have been developed and tested. Temperature dependence dynamic viscosity has been modeled using a polynomials 3rd and 4th degree. The proposed models can be used for prediction of fl ow behaviour of oils. With monitoring and evaluating we can prevent technical and economic losses.
