BMW Exhaust Manifold
Ševčík, Miroslav ; Beran, Martin (referee) ; Svída, David (advisor)
This master´s thesis describes design and optimalization of the exhaust mainfold and an effective muffler for BMW 320i E30 car. This car is equipped with 6 cylinder engine M20B20. The construction is carried out with regard to the rules laid down by FAS Czech Republic. I used theoretical knowledge and Lotus Engine Simulation software in this thesis.

Dynamic Characteristics of Exhaust System and Noise Transmition to the Car Cocpit
Novotný, Václav ; Ramík, Pavel (referee) ; Svída, David (advisor)
This thesis deals with the complex analysis of dynamic characteristics of the exhaust system and the transmission of noise from exhaust system to the vehicle. In the first part is performed modal analysis, which is compared to experimentally measured data. Modal analysis of the complete exhaust system is made with focusing on the influence of temperature of the exhaust system. There is also performed an analysis of noise transmission from exhaust system to the car cockpit.

Modeling of Exhaust Manifold for Turbocharged Engine
Fanta, Tomáš ; Beran, Martin (referee) ; Svída, David (advisor)
This work describes different structural designs of the exhaust manifold and creation of parametric models of exhaust downpipes of supercharged engine 1,4 TSI. Next, the study deals with exhaust manifold’s materials and with present basic principles of thermodynamic and hydrodynamic. Then two parametric models were modelled in Solidworks software. First model was made according to existing exhaust manifold of engine 1,4 TSI. It was symmetrical model (collector in the axis). For second parametric model the collector was moved in horizontal direction, so this model is asymmetrical. Both models were evaluated considering their complexity of structural design and their manufacturing claims. Finally the possibility of CFD analysis for evaluation of parametric models was studied.

Petrol Direct Injection
Moravec, Tomáš ; Janoušek, Michal (referee) ; Dundálek, Radim (advisor)
This bachelor thesis is about the system of direct injection petrol engines within cars. The first chapter is designated to the history of the direct injection petrol system and the development of different concepts. The thesis then concentrates on the mixing of air with fuel and describes the injection system in detail. Within the content of my work is a list of specific engines, using the direct injection system. The last chapter is devoted to the future development of direct injection petrol system and those with the compression-ignition system.

Noise impact of combustion engine exhaust systems
Ptáček, Petr ; Knotek, Jiří (referee) ; Zubík, Martin (advisor)
This bachelor’s thesis is focused on creating a research study about noise of combustion engine exhaust systems. Introducing of this work coves all parts of common exhaust systems while mostly focused on silencers. It further describes several methods of measuring the noise established by legislation and at its end it deals with a noise impact of exhaust system treatments.
