Charge Efficiency of a Gasoline Turbocharged Engine
Holas, Tomáš ; Böhm, Michael (referee) ; Svída, David (advisor)
This bachelor thesis deals with the topic of volumetric efficiency of a gasoline turbocharged engine. The first part of this thesis is devoted to research on this topic. In the second part of the thesis an analysis of data from a 1.5 TSI engine from the Volkswagen group line-up obtained during the WLTP test was performed. This analysis was achieved by the means of creating regression models on the measured data and comparing their results. The result of this analysis was the determination of the main ordinarily measured parameters on which the volumetric efficiency depends.

Increasing the Volumetric efficiency of a two-stroke engine
Šmahel, Matěj ; Drápal, Lubomír (referee) ; Beran, Martin (advisor)
This bachelor thesis deals with a design modification of a chosen two-stroke engine with respect to an increase in its filling efficiency resulting in increased performance. The first part of the thesis describes basic principles of a two-stroke engine alongside a detailed description of all its cycles and their influence on the filling efficiency. The second part is dedicated to the design modification itself ending with a result evaluation.

Increase of Charging Efficiency of 140kW CNG Engine
Hadrava, Martin ; Vančura, Jan (referee) ; Svída, David (advisor)
The master’s thesis is focused on flow analysis work filling in turbocharged CNG engine. The research method is reverse engineering. The intake canal is casted and than scanned by 3D Scanner ATOS. The CAD model is created in program Creo Parametric 2.0. In the created interactive model is simulated flow in the CFD program Star CCM +. The air intake system is modified for increasing the charging efficiency of the engine.
