UTILIZATION OF BIOGAS IN TRANSPORT
Štylárek, Milan ; Zháňal, Lubor (referee) ; Vopařil, Jan (advisor)
Objective of this bachelor thesis is evaluating the possibility of utilization of biogas as an alternative fuel for combustion engines in traffic. Production and distribution of upgraded biogas is described as well as situation of its utilization in the world. This is followed by a comparison of situation in biomethan utilization in Czech republic and Sweden. There are explained barriers to commercial placing and its possible eliminating. In the end the model study of replacement of farm vehicle fleet for CNG vehicles is described.

Intake Manifold for 140kW CNG Engine
Wojcik, Rudolf ; Beran, Martin (referee) ; Svída, David (advisor)
The master´s thesis is focused on the design of the multi-point CNG injection for the VW 1.4 TSI intake manifold turbocharged spark ignited engine. The 3D model that was created using Autodesk Inventor Professional 2012 is based on the real intake manifold. This model served as an input for CFD analyses of mixing CNG with air. These were made in STAR-CCM+ software.

Fuel for internal combustion engines
Vrbický, Jiří ; Jedelský, Jan (referee) ; Štětina, Josef (advisor)
This thesis is concerned with basic features of fuels for internal consumption engines, especially their influence on thermal efficiency. It also introduces dividing of fuels and their compare in ecologic, economic and technologic side. It is concerned convectional fuels (gasoline, diesel oil) and alternative fuels (nature gas, bottled gas, hydrogen, biodiesel, biogas, methanol and ethanol).
