HCCI engines
Otáhalík, Pavel ; Šebela, Kamil (referee) ; Štětina, Josef (advisor)
This bachelor thesis deals with the problematics of HCCI engines. Due to later required knowledge of fundamental principles, the beginning of the thesis is devoted to the history of combustion engines, the principle of their function and their division by basic criteria. The following section consists of the description of petrol and diesel engines in terms of the principle of the mixture formation and its combustion with emphasis on their advantages and disadvantages. In the central part of the thesis, which focuses on the HCCI engines, various mixtures creation methods and ignition are described. Next, the HCCI engines are described in terms of emissions including current concepts solutions. Finally, the conclusion of the thesis consists of speculation of the future of combustion engines and their prospective alternatives.

Capacitive Ignition System
Benček, Kristián ; Bazala, Jiří (referee) ; Beran, Martin (advisor)
Bachelor thesis deals with the complex issue of ignition system, with a special emphasis put on the capacitive ignition. Due to the later needs the knowledge of the principles, on the basis of which the individual internal combustion piston engines work is the beginning of a work dedicated to the just distribution of these engines according to the basic criteria and elementary define different types of piston internal combustion engines and storylines, which in them take place. Subsequently is described in detail dismantled the issue of the kindle system as a whole but also the individual components of the ignition system and attention is required even to properly set the most suitable moment of ignition (pre-ignition) and the need to ensure sufficient ignition energy. Ignition systems are divided according to the historical development from the earliest induction of the classical ignition until after the state of the art fully electronic ignition system. The greatest emphasis is put on detailed analysis of the capacitive ignition, which is then compared with the conventional ignition. The last part is devoted to the management of the combustion event using the initialization of the burning. As an example, that the management of the combustion event using the initialization of the burning is nowadays a real, is referred to the engine Skyactive X, which should be in 2019, the commonly commercially used in the model of the Mazda 3.
