Engine Cycle Design for Plug-in Hybrid
Koutník, Štěpán ; Kudláček, Petr (referee) ; Novotný, Pavel (advisor)
The content of this thesis is analysis of energy flows of the propulsion system in plug-in hybrid utility vehicle. Theoretical part of the thesis deals with electrically assisted turbochargers, which can positively influence engine characteristics. The following part analyses given diesel engine and utility vehicle in simulations in GT-Suite software, with simulations being performed on WLTC driving cycle. The results of the simulations demonstrate the relation between the usage of electrical and fuel energies and the driving cycle and show the engine operation points. By using optimal battery capacity, it is possible to save according to driving cycle more than 50 % energy consumed by the engine, directly influencing the fuel consumption. The results are possible to use as a guidance for moving the engine operation points and for sizing of the battery pack of hybrid utility vehicle according to real life application.

Real consumption of primary energy of plug-in hybrid and electric cars
Bochníček, Ondřej ; Pokorný, Jan (referee) ; Fišer, Jan (advisor)
The topic of bachelor thesis is to evaluate a consumption of primary energy in electric cars and plug-in hybrids depending on the place of the operation and also to compare a particular representative with similar classic cars with combustion engine. Another criterion used for evaluation is the emission of carbon dioxide for one driven kilometer. For the consumption of primary energy in electric cars and plug-in hybrids is essential to know how is the electricity produced in the chosen area. With the energy mix of each state, characteristics of given ways of producing electricity and consumptions of selected cars the consumption of primary energy of selected cars and emission of carbon dioxide for one driven kilometer were determined. From the computed data results, that the lowest energy consumption have the electric cars driven in countries with dominant representation of renewable energy sources. Conversely the worst conditions are in the countries with high part of fossil fuels in electricity production. From the comparison of single electric cars and plug-in hybrids with classic cars results that electric cars or plug-in hybrids are at the time of writing this thesis practically in all cases more energy efficient and also produce less emission of carbon dioxide.

Vozidla s hybridním pohonem
Vančatová, Šárka
The Bachelor thesis deals with hybrid engines applied at cars. First of all there is a historical overview of these engines and then there is a description of their principles and types. In this chapter are also in sum pros and cons of hybrid vehicles. It shows technical properties of a few chosen road vehicles which have similar power and are available in the Czech Republic. Last but not least chapter describe analysis of the chosen technical parameters. Necessary data were downloaded from web pages of Czech car sellers.
