Cooled EGR system loop architecture for gasoline engines
Pospíšil, Juraj ; Svída, David (oponent) ; Bazala, Jiří (vedoucí práce)
This master s thesis is focused on proving the effects of different exhaust gas recirculation architectures on turbocharged gasoline engines. Simulations were made in thermodynamic simulation software GT-Power. It starts with comparing the effects of different exhaust gas recirculation architectures on the steady-state simulations, mainly from the fuel consumption aspect, which are later implemented into the transient models running emission test cycles. At the end of the thesis are described impacts of exhaust gas recirculation on the function of three-way catalyst and function of the turbocharger.

Decreasing of generation of emissions of already produced passenger cars with spark ignition engines in EU
Hálek, Dominik ; Beran, Martin (oponent) ; Bazala, Jiří (vedoucí práce)
This bachelor thesis is dealing with reduction of unwanted emissions of passenger cars given by EU standards. The thesis is focused particularly on idea of fitting of already produced passenger cars with spark ignition engines, that meet older emission standards, with a system, that can reduce this unwanted emissions coming from the exhaust pipe. Outcome of this work is summary of basic retrofits, theoretical calculation of reduction of emissions for cars equipped with selected retrofit and decision about using retrofits as an appropriate component for decreasing of emissions, especially CO2 emissions.
