NOx Reduction System
Karafa, Pavel ; Bradávka, Marek (referee) ; Svída, David (advisor)
This diploma thesis deals with the issue of nitrogen oxides emissions in exhaust gases and possibilities of their reduction. The task of the thesis was analysis of systems for NOX reduction by contemporary diesel engines, design and construction of NOX reduction device for given diesel engine, then verify functionality of this system compiled from commercially available components. In the last part of thesis available measurements will be made with an analysis of achieved results.

Engineering design of the vehicle suspension rocker
Poláček, Vojtěch ; Ramík, Pavel (referee) ; Bradávka, Marek (advisor)
Diploma thesis deals with the design and stress analysis of the rocker suspension for an autocross car. The research describes some real cases of using suspension with pushrod and rocker in motorsport. Subsequently, the work deals with the design of the wheel bump/rebound limiting stops and bump/rebound measuring. The challenge is to design a component shape, size and select fit of a rocker with an emphasis on low weight whilst maintaining sufficient strength and rigidity. The design study include stress analysis which leads to optimize the final shape.

Turbocharged 1,2L Spark Ignition Engine
Věříš, Michal ; Svída, David (referee) ; Bradávka, Marek (advisor)
This diploma thesis is focused on performance options for turbocharged 1.2 litre spark ignition engine. First of all, couple of engine variants are compared and the most suitable one is chosen. Production turbocharger is determined upon the calculation of compressor parameters. Simulation in Lotus Engine Simulation and GT-Power is done to confirm co-operation of turbocharger with engine. Two stage serial turbochargers are also compared and the most effective pair is chosen for simulation. Research through the possibilities for increase the power output and the detail focus on turbochargers is also part of this thesis.

Honda Turbocharged SI Engine
Malec, Petr ; Bradávka, Marek (referee) ; Svída, David (advisor)
This diploma thesis describes the design of a suitable filling turbocharger for gasoline engine Honda 1.98L. Includes professional research existing systems used for charged gasoline engines. Another part is a calculation to determine the correct parameters of the compressor and turbine. At the end is a simulation of selected turbocharger and engine work together using GT Power software simulation.

Piston for SI Turbocharged Engine 2.0L
Kusyn, Petr ; Bradávka, Marek (referee) ; Svída, David (advisor)
This diploma thesis is focused on solve of design solutions for piston for turbocharged version of Honda K20A engine, especially on reduce of side force acting on piston. There are mentioned methods and on their basis also design solutions for piston to reduce this force. There is also included kinematic and dynamic analysis for each solution and as well their FEM analysis for testing the suitability of these solutions.
