Gas exchange systems of two-stroke engines
Kovář, Michal ; Kučera, Pavel (referee) ; Píštěk, Václav (advisor)
This bachelor thesis is focused on the analysis of the development and critical evaluation of the gas exchange system of two-stroke engines. The aim of the work was to use research to concentrate various options for gas exchange system of two-stroke engines of various power categories, to describe individual solutions and point out the advantages and disadvantages of individual systems and then outline possible future developments in this area.

Optimalization of Exhaust Manifold for SI Engine
Prášek, Martin ; Beran, Martin (referee) ; Svída, David (advisor)
The master thesis is focused on optimizing existing or proposal for a new exhaust tracts on the Volkswagen Polo moving series rally-cross A1 division. The car is powered by concern, water-cooled, atmospheric engine capacity 1599 ccm. To achieve the objectives of the lessons are applied as a theoretical nature (analytical calculation), especially the advanced approaches of the software environment from the firm Lotus. Exhaust treatment systems are designed to suit all rules FIA Sports Association.

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.

Exhaust Manifold for Formula Student Engine
Bartoš, Tomáš ; Beran, Martin (referee) ; Svída, David (advisor)
The aim of this diploma thesis is the design and tuning of the exhaust manifold and muffler for the Formula Student car. The single cylinder atmospheric spark ignition engine Husaberg FE 570 is used as a powertrain unit. The exhaust system is designed according to the Formula Student rules. To design the exhaust system has been used as theoretical knowledge as well as software Lotus Engine Simulation.

Modification of a motorcycle spark ignition engine
Poulíček, Matěj ; Ramík, Pavel (referee) ; Kaplan, Zdeněk (advisor)
This diploma thesis is about possible modifications of four-stroke motorcycle petrol engines for increasing power. It also deals with the modification of the Aprilia Leonardo 250 engine from a 2-valve variant to a 4-valve variant, the simulation of this engine and the proposed solution in the GT SUITE. Attention is also paid to the strength control of the crank mechanism of the engine.

Exhaust Manifold for Formula Dragon 3
Brezanský, Vít ; Janoušek, Michal (referee) ; Svída, David (advisor)
Main goal of this thesis is to design exhaust manifold for Formula Student car Dragon 3. Construction parameters follow requirements on high engine power and also have to meet some restrictions given by competition rules. Lotus Engine Simulation software was used for modelling the engine (originally from Husaberg FE 570 motorcycle) and for determination of influence of the exhaust parameters on power characteristics. This thesis is also dedicated to noise emitted by the exhaust system which is important due to Formula Student rules.
