Multi-point Injection
Slavík, Tomáš ; Svída, David (referee) ; Dundálek, Radim (advisor)
The main objective of this Bachelor degree thesis is to describe and to bring closer the function of the multiple fuel injection system (nebo the function of fuel injections with multiple sets) in spark-ignition combustion engines, as well as to create a summary of individual components in fuel injection frameworks together with describing their functions and comparing them with other alternatives in fuel systems. In the conclusion, an elaboration on development trends in combustion engines will be provided.

Vliv tepelné elektrárny na životní prostředí
Huvar, Karel
Combustion of fossil fuels in the energy sector is one of the largest sources of air pollution in the Czech Republic. This thesis describes the conversion of heat energy in coal power plant into electricity. It compares the combustion plants of solid fuel. It compares combustion of coal, biomass and solid alternative fuels. It analyzes the resulting pollution from the combustion of solid fuels and its impact on the environment. It also describes the use of cogeneration. There are mentioned the methods of disposal and elimination of harmful substances and waste products of solid fuels combustion and their use. It deals with a preview of the future of classical power engineering in the Czech Republic.

Alternativní pohony motorových vozidel
Puchnar, Lukáš
This Bachelor thesis focuses on the possibilities of using alternative fuels to operate the vehicle. In the first chapters, there is a review of fossil fuels used, its properties and monitored emission parameters. The following section is devoted to gas fuels, problems associated with the storage in the vehicle and engine modifications. Further are descri-bed biofuels, its production and application in combustion engines. Subsequently the electric vehicles is briefly described, current state and performance characteristics of this type of vehicles. The distribution of hybrid vehicle propulsion systems follows. The final section focuses on the economic comparison of selected alternative drives, its af-fordability and costs of operation.

Ekonomické aspekty využívání dendromasy pro energetické účely
Badal, Tomáš
The focus of this work is on the economic aspects of using dendromass (logging residues) for energy purposes in the production of energy chips. In defining economic factors, the paper employs as a basis actual manufacturing and sales data from 247 business cases in 2011-2012 at nine forest properties. The data reflect 44,971 m3 of harvested wood, 6671 tons of energy chips with a total energy content of 63.92 TJ. The initial objective of the paper is to derive average and proportional variables using data from actual business cases and then use these to discover the limiting production values, particularly those of the purchase price and energy chips, as well as logging residues and the limiting transport distance. The relationships derived are shown both mathematically and graphically. Results found in the paper are primarily designated for preproduction calculation by economic entities, the valuation of logging residues and as a basis for national policy regarding both forests and energy.
