Testing of the Common-rail pressure regulation valve by ADwin device
Šoulák, Vojtěch ; Svída, David (referee) ; Kučera, Pavel (advisor)
Tato diplomová práce se zabývá rozšířením testovacích možností vývojové stanice pomocí zařízení ADwin. Hlavní částí diplomové práce je navržení přídavného okruhu testovací stanice a naprogramování testu pro tlakový regulační ventil. V další část se diplomová práce zabývá předpokladem stavu komponent regulačního ventilu po testování. Při porovnání tohoto předpokládaného stavu a reálném stavu po testování je ověřeno správné naprogramování testu a správná funkce nově navrženého okruhu.

Dieselgas Engines
Březina, Tomáš ; Böhm, Michael (referee) ; Štětina, Josef (advisor)
This bachelor thesis deals with the topic of Dieselgas engines. The first part work is focused on the history and development of engines and motor fuels. The second part deals with diesel engines, a description of the engine operating cycle, fuel injection system, types of diesel fuel, engine efficiency and emissions. The following chapter provides an overview of gaseous fuels suitable for passenger and public transport. Of these fuels, the two most commonly used are further elaborated. The fourth chapter deals with the use of gaseous fuels in diesel engines, the possibility of conversion of these engines, both by conversion to petrol and without this change. The last chapter deals with the effect on consumption and emissions of dual fuel engines.

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.

Internal combustion engine control in the LabView environment
Adamec, Vojtěch ; Kučera, Pavel (referee) ; Svída, David (advisor)
This thesis deals with the control of a diesel internal combustion engine. The aim of the thesis was to make a methods overview of diesel internal combustion engines control, to develop an algorithm for a six-cylinder diesel engine control and then to program it in the LabView environment. The thesis also describes the calibration of sensors and engine control unit. The algorithm was tested using a programmed signal generator and an oscilloscope.

Design of Diesel Aircraft Engine One-cylinder Engine with Contra Rotating Pistons
Svoboda, Tomáš ; Drápal, Lubomír (referee) ; Novotný, Pavel (advisor)
Diploma thesis deals with design of crankshaft for two stroke opposed piston diesel engine. In the theoretical research part a history, comparison with competitive engines in nowadays light aircrafts and the advantages of opposed piston engines are mentioned. In the practical part the balancing is chosen and CAD model of crankshaft is designed. Geometry of this model is than checked for fatigue damage fallout. In the final part was chosen the propeller and appropriate reduction gearbox.

Fuel injection pumps for diesel engines
Kovářová, Lucie ; Beran, Martin (referee) ; Píštěk, Václav (advisor)
Bachelor thesis about "Fuel injection pumps for diesel engines," deals with fuel injection pumps for diesel engines and their development. The goal of this thesis is to describe and explain the principle of fuel injection pumps and to categorize them according to their design solution. The categorization begins with the first historical usage of fuel injection pump and ends by outlining the future usage of this technology.
