Effect of additives on wear reduction of rubbing surfaces
Súkeník, Juraj ; Dzimko, Marián (oponent) ; Křupka, Ivan (vedoucí práce)
Lubricants additives are inseparable component of modern high-tech lubricants. Viscosity index improvers additives play uncoverable role in a branch of boundary lubrication. They are designed to ensure sufficient oil film thickness in low speeds of frictional surfaces motion. This thesis deal with effect of specific viscosity index improvers additives on boundary lubrication film formation in elliptical contact. The purpose of this work is also checking the effect of concentration changing these additives on lubricantion film thickness formation.

Lubrication of combustion engines in 21st century
Súkeník, Juraj ; Nevrlý, Josef (oponent) ; Křupka, Ivan (vedoucí práce)
Lubrication is inseparable part of internal combustion engines. It primary influences operation, lifetime and efficiency of internal combustion engine. This bachelor`s thesis summarizes present state and future view of internal combustion engine lubrication. The work deals with tribology of several engines sections and composition of present lubricants for internal combustion engines.
