Unconventional heat cycles
Snášel, Jan ; Košner, Jan (referee) ; Jedelský, Jan (advisor)
The bachelor thesis is describing four unconventional heat cycles and devices which are using them. It is Stirling cycle, organic-Rankine cycle, Kalina cycle and Brayton cycle. The cycles are described in terms of the main parts of their devices and in terms of their thermomechanical principle. In thesis are also stated applications for each cycle and their advantages and disadvantages. There are also stated formulas for the ideal cases of cycles to calculate specific work done, specific input heat flow and efficiency of cycle.

Ideal cycles of internal combustion engines
Marušák, Ondřej ; Jedelský, Jan (referee) ; Štětina, Josef (advisor)
The thesis set out the basic thermodynamic circulation and their properties. For these orbits are shown ideal cycles gas engine and diesel engine, in which investigating thermal efficiency depending on the change in their characteristic parameters. The results are reported in tables and diagrams. For each of the engines is also a table with most values the compression ratio, the final compression pressure, the final compression temperature and maximum combustion pressure. Finally, we compare the thermal efficiency of the two orbits in the T-s diagrams.

Comparison of traditional and nontraditional cycles of heat engines
Dobiáš, Ladislav ; Jedelský, Jan (referee) ; Štětina, Josef (advisor)
The bachelor thesis describes the thermodynamic cycles of four-stroke spark ignition (SI) and compression ignition (CI) engine, Wankel engine and two-stroke spark ignition (SI) engine. Based on the information is compared with thermal efficiency of each engines with four-stroke spark ignition engine in the T-S diagrams. There were also dedicated to Atkinson cycle and its use in practice. The last part deals with the construction of a variable compression ratio used in the development of modern engines.
