Measurement of internal combustion engine performance on a chassis dynamometer
Farka, Jan ; Ramík, Pavel (referee) ; Štětina, Josef (advisor)
Since the beginning of the automotive industry, a lot of years have passed and the characteristics of vehicles and all its components, especially the engine, are being given greater and greater emphasis both in terms of safety, performance and ecology. The performance of the internal combustion engine, along with a number of other vehicle features, is measured on chassis dynamometers. The aim of the thesis is to describe and analyse the dynamometers produced, the tests performed on them and also to measure the performance of the internal combustion engine on the chassis dynamometer. In conclusion, the assessment of the impact of tests on the automotive industry is just mentioned.

Increasing Single Cylinder SI Two-Stroke Engine Performance
Stejskal, Miroslav ; Drápal, Lubomír (referee) ; Svída, David (advisor)
This thesis deals with two-stroke engine design modifications to enhance its performance parameters. The introduction summarizes the various solutions of two-stroke engines. The next part deals with design modifications of the engine power, their implementation and subsequent modification. The work includes strain and stress analysis of the piston, which includes a complete indication of pressures in two-stroke engine. The achieved results of FEM analysis were used to design better piston geometry.

Measuring the power of IC-engines
Adamec, Vojtěch ; Ramík, Pavel (referee) ; Štětina, Josef (advisor)
This bachelor thesis deals with topic measuring the power and the torque of internal combustion engines on chassis dynamometer. The aim of the thesis was to show advantages and disadvantages of different types of dynamometers, to make review of standards for measuring power on chassis dynamometer, effect of atmospheric conditions, resistances and slippage. Thesis also describes evolution, different designs of chassis dynamometers, effect of roller diameter to rolling resistance and deformation of tire, suitable types of dynamometers for chassis dynamometer, equipment of testing room, modes of operating and differences between static and dynamic power testing. In the end I have made prediction of incoming development devices of this type with regard to evolution of intelligent chassis control systems and electric vehicles.

The use of a chassis dynamometer in automotive development
Obid, Daniel ; Březina, Michal (referee) ; Štětina, Josef (advisor)
This bachelor's thesis deals with the use of chassis dynamometers, which are an integral part of the development centers of the world's automobiles. The main goal was to create an overview of design solutions. Using information materials from AVL, the use of these dynamometers in automotive development was summarized. The used measuring cycles and their development after the "DieselGate affair" were presented.

Stanovení parametrů motocyklového motoru na válcovém dynamometru
Paráček, Marek
This diploma thesis focuses on the topic of engine and chassis dynamometers. Emphasis is given to historical development as well as current findings in this field, especially in field of motorcycle dynamometers. This diploma thesis also describes the motorcycle engine and its main structural parts. The practical part of this diploma thesis deals with measuring motorcycle parameters by using a chassis dynamometer. These parameters have been measured with various combinations of air filters and exhaust silencers. In the evaluation process, results based on measurements have been displayed as graphic dependences. The discussion part goes on and presents recommendations and proposals for the practical use of the motorcycle. These proposals and recommendations are based on measured values.
