Klasické a alternativní pohony motorových vozidel
Widholm, Tomáš
This thesis is focused on the classic and alternative drives of cars. First part of the thesis deals with history and present of classic combustion engines. Next part is focused on the environmnetal effect of classic engine cars and alternatively driven cars. The end of this thesis is focused on concrete alternative drives. First part are gas drives, hydrogen drives and fuels cells. Further the thesis deals with electromobiles and finally hybrid drives, because they are widespread today. These chapter describes their functions and introduces the necessary components. The end of the chapters includes positives and negatives of each drive, together with its valuation. The end of the thesis inculudes some examples of production hybrids, together with their parameters.

Bycicle with Combustion Engine and Electrical Transfer of Power
Mazálek, Tomáš ; Huták, Petr (referee) ; Vorel, Pavel (advisor)
The objective of this semester thesis is design of the control algorithm, needed control and power circuits and PCB design for the unfinished bicycle concept with a combustion engine and electric power transmission. The control algorithm had to be designed to make efficient use of the combustion engine performance and to minimalize the fuel consumption and noise level of the device. All circuits are fully implemented by analog components for which were designed printed circuit boards using program Eagle and this boards were revived and debugged.
