Combustion engine active exhaust muffler.
Hurt, Libor ; Blaťák, Ondřej (referee) ; Rasch, František (advisor)
The object of this thesis are the active exhaust mufflers of internal combustion engines. This thesis is specialized on function description such a mufflers and on a technical design, including systems, which are very similar to those active systems. Further work describe the using analogous systems at motorcycles and it how with four stroke engines so with two stroke engines.

Belt Drive for Valvetrains
Tomanec, Filip ; Rasch, František (referee) ; Novotný, Pavel (advisor)
This bachelor’s thesis deals with belt drive of valve timing mechanisms, estimation of their vanteges or disavantages. In the first section treat of drive for valvetrains generally, summary description of different drives types and comparison their features and right application. In the second section deals specially with toothed belt systems – construction of toothed belts, their types, marking, most frequent failure, tension and guide. In the last section is showed real solution of timming belt drive.

Passenger Cars Four Wheel Drive.
Hrádek, Zbyněk ; Rasch, František (referee) ; Blaťák, Ondřej (advisor)
The aim of my Bachelor´s project is to form the search describing individual drive concepts of the all cars´ wheels. It is focused especially on the construction, working principle and usability of the particular concepts. The beginning of the thesis is interested in the the history as well as the advantages and disadvantages of this engineering solution. In the following part the most used drive concepts are described. The end of the project covers the summary of the acquired information and the consideration of how the all wheels´ drive will be developed in the following years.

Gear Timing Mechanism for Valvetrains
Drdla, Adam ; Rasch, František (referee) ; Novotný, Pavel (advisor)
The objective of this thesis is to provide an overview of geared valvetrain. In introduction are described individual types of gears and their application in combustion engines. Then, the thesis is divided into three chapters. The first chapter provides a thorough analysis of geared valvetrain. Also, individual parts of valvetrain together with alternative methods of valve timing are briefly introduced. The chapter then follows to examine the working principle of gears, how forces and moments are transmitted, advantages of introducing helical gears instead of spur gears, different ways of gear manufacturing, gear material selection, heat treatment of gears and common gear failure mechanisms. The second chapter examines pros and cons of using geared valvetrains. The third chapter shows examples of how are geared valvetrains applied in tractors, trucks, ships, trains, cars and motorcycles. In the conclusion, the main advantages of using geared valvetrains are discussed and the whole thesis is summerized.
