Degradace motorového oleje ve vznětovém motoru osobního automobiluOral, Martin January 2016 (has links)
The thesis is focused on the problems of degradation of engine oils of the same viscosity class 5W-30.The first part of the thesis is describing lubricating systems and their component parts. The thesis also focuses on the division of oil in each classification and description of its properties. Samples of the oil have been taken from two cars with identical diesel engine, but with different total traveling distance. Attention is paid to the amount of structural metals, contaminants and additives in both oils, and throughout the oil usage interval. The results are interpreted graphically and various dependencies are modeled using appropriate regression functions. Thesis compares the mechanical and physical properties of engine oils, depending on mileage. The conclusion summarizes the evaluation and the results obtained.

Teplotní závislosti různě viskózních automobilových motorových olejůPiták, Jan January 2016 (has links)
This thesis is focused on the determination of the temperature dependence of automotive engineoils with different viscosity class. The first part of the thesis describes the individual functions, properties and composition of engineoils which it is possible to meet the automotive industry. Experimental part deals with temperature dependence density and viscosity of five new engine oils and one used engine oil with the same specification as one of the new oil. The four oils are classified with synthetic base and one with mineral base. The viscosity measurement was carried out using digital rotary viscometer Brookfield DV2T LV and the density measurement was carried out using a digital densitometer Densito 30 PX. As expected, the values of shear stress, dynamic viscosity, kinematic viscosity and density decreased with increasing temperature. Temperature dependence of density and viscosity of oils was modelled using an exponential function, in which were subsequently evalued coefficients of determination R2.
