"Start&Stop" system spark ignition engine, passanger car implementation
Kubiš, Milan ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
My bachelor work describes a system implementation Start&Stop and its usage in passenger cars with gas engine. The work details reasons for the usage of this system and technically describes the basic elements. It shows different constructions of the systems, their advantages and disadvantages, both from the point of the influence over the car movement and in terms of the motoring comfort and the safety of running, especially in the urban environment.

Direct injection systems for spark-ignition engines
Vondráček, Václav ; Rasch, František (referee) ; Drápal, Lubomír (advisor)
This bacheleor´s thesis deals with direct injection of fuel spark-ignition motors. In each chapter you can learn about principle activities injection of fuel, meet single parts and components and learn how these components work. Further, this work compare some constructional differencies of the systems of some automobile producers and observes contemporary general way of those problems with reference to future.

Powertrain of experimental single-cylinder spark ignition engine
Laštovica, Karel ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
These bachelor’s thesis deals with experimental single-cylinder engine, calculation of his thermodynamic cycle, design of a piston, design of a can rod eye and his strength check. In introduction there is states function principle of combustion engine and their basic division and application. The bachelor’s thesis consists of five parts: scheduled initiatory parameters, calculation of thermodynamic cycle, calculation of the piston group weight, calculation of forces reacting to piston group and strength check of con rod eye. In the conclusion results of calculation are evaluated.

Crank mechanism of in-line four-cylinder spark ignition engine
Marek, Petr ; Rauscher, Jaroslav (referee) ; Píštěk, Václav (advisor)
Objective of this bachelor’s thesis is for given geometric, thermodynamic and operation parameters cylindrical unit of in-line four-cylinder spark ignition engine perform calculation of thermodynamic cycle, project basic proportion of piston group and for given operation modes perform strength check of connecting-rod eye. In the introduction is described ordinary use of spark ignition engines, several details of history of their evolution and present most widly used construction. Major text of bachelor’s thesis attend to four main chapters: description of thermodynamic cycle, calculation of forces reacting to piston, strength calculation and check of piston pin and of connecting-rod eye. Supplement consists of accomplishment of these calculations and a few of graphs. In the conclusion is evaluation of performed calculations and there are mentioned technological directions of present evolution of gas-engine.

Powertrain of experimental single-cylinder spark ignition engine
Číp, Tomáš ; Rauscher, Jaroslav (referee) ; Píštěk, Václav (advisor)
Objective of bachelor’s thesis is, for noted geometric, thermodynamic and operation parameters cylindrical unit of experimental single-cylinder spark ignition engine, perform calculation of thermodynamic cycle, project basic proportion of piston group and for noted operation modes perform strength check of connecting-rod eye. In preamble is stated basic use of spark -ignition engines, their operation principle and basic fisson. The bachelor’s thesis is consists from of calculation, which is continuously described.The calculation is consists from four parts. The first part is calculation of thermodynamic cycle, in the second part are calculated concept piston group, in next part are calculated forces reacting to piston group and fourth part is strength calculation and check of connecting-rod eye. In the last part is results evaluation of calculation.

Animované modely tepelných motorů
Honzl, Michal
The present diploma thesis "Animated models of heat engines" describes the design of an interactive application. The theoretical part deals with the classification of heat engines and their rotations. The result of the present diploma thesis is the new application "Animation of heat engines" designed in Flash programme. This application is focused on the basic function principle of four demonstrated engines. The present work also deals with assessing and comparison of real engines, their cuts, real models and animated engines.
