Combined supercharging internal combustion engines
Melichar, Marek ; Mauder, Tomáš (referee) ; Štětina, Josef (advisor)
This bachelor’s thesis contains a basic division of various types of combined supercharging and a description of their functions. For the most common types of supercharging technologies there are listed specific examples of usage in the automotive industry. This thesis also contains a short overview of the history of supercharging and an analysis of ideal cycles supercharged internal combustion engines. One of the most important chapters of this thesis is thermal efficiency of supercharged engines and their comparison with naturally aspirated internal combustion engines.

Reversing cross for flexo printing machine
Falta, Jan ; Mazal, Pavel (referee) ; Brandejs, Jan (advisor)
The aim of this work is to develop a new concept of the reversing cross for flexo printing machine SomaFlex Optima. Work includes a description of the machine, the basic description of the principle of flexography. There is explained the principle of turning the material, the current method of supplying air to the air cushion and the difference between the blower and compressor as an air source for the air cushion. Conceptual solution includes two variants, namely vertical and horizontal position of turning bars. For each alternative are described its advantages and disadvantages.
