Instalation of AR64304 Engine
Kubiš, Vojtěch ; Beran, Martin (referee) ; Svída, David (advisor)
This diploma thesis is concerned about installation of AR64304 engine into Alfa Romeo 75. The main goal of this thesis is a design of exhaust system for AR64304 engine installed in the engine bay of the vehicle. The design of the exhaust system was done with a respect to the noise and emission requirements, as well as with a respect to the performance of the engine. Lotus Engine Simulation software was used for the simulation of the engine with proposed exhaust system. Input data for the simulation were obtained from measurements of the cylinder head on a flow bench and precise measurement of camshaft profile. The essential contribution of this work is a set of construction parameters of the exhaust system. This thesis also contains technical specifications of AR64304 engine and the installation process.

Intanke and exhaust manifold for racing engine
Chuchma, Ondřej ; Zháňal, Lubor (referee) ; Beran, Martin (advisor)
This Master’s thesis is focused on design and optimalization of intake and exhaust system of the C20XE engine. It is four-cylinder gasoline engine with stroke volume of two litres, which was produced by car company Opel. This engine is determined for Opel Astra F automobile, that is build for racing. For optimalization of dimension parameters there is used a Lotus Engine simulation software, which simulates one-dimension gas flowing in manifold. 3D CAD models are made in Pro ENGINNER software.

VD Vlachovice - concrete gravity dam
Juriga, Jan ; Šulc, Jan (referee) ; Zachoval, Zbyněk (advisor)
As a part of this bachelor thesis an alternative design of the concrete gravity dam VD Vlachovice was made, to the already design of the earth-fill dam. The design of the outlet works, intake and spillway were also carried out as a part of the study. The introduction of the thesis includes a description of the site and an evaluation of local conditions. The next part deals with the stability of the dam and the load-bearing capacity of the subsoil. Furthermore, the design of the outlet works, intake and spillway were made. A part of the thesis also deals with the transformation of flood by the water reservoir. Finally, drawings and simplified 3D model of the dam were created. The documents necessary for the creation of the work were provided by company AQUATIS a.s. with the permission of Povodí Morava, s.p.

Tractor Engines Intake Systems Overview
Pacovský, Tomáš ; Svída, David (referee) ; Dundálek, Radim (advisor)
The main focus of this work is creation of textual and pictorial documentation of equipments used on nowadays tractor engine intake systems. Firstly author is focused on introduction of individual parts of intake system with their detail function description and pictorial documentation. After that the separate intake systems overview is made via world known tractors such as Case IH, Deutz – Fahr, John Deere, Massey Ferguson and New Holland. Every representative of tractor is introduced with its overview and pictures of the most significant parts concerned with inletting of air into the engine. The entire pictures documentation of intake systems overview is made by camera at the place of tractor’s dealer and when this photo documentation was unsatisfactory, the www pages of dealers was used. This bachelor’s thesis should show the progressive development of intake system’s individual equipments. Eventually this thesis can be used to evolve another research projects.

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.
