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.

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.

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.

Multistage turbocharging of diesel engine
Vichr, Tomáš ; Beran, Martin (referee) ; Svída, David (advisor)
This master thesis summarizes the basic knowledge in the field of turbocharging of internal combustion piston engines. It also focuses on the analysis of some properties of multistage turbocharging, especially for diesel engines. Using analytical relationships, a model in the form of a web application has been created, which describes the cooperation of a turbocharger or turbochargers with an internal combustion engine. With the help of this model, some two-stage supercharging options for the selected engine have been then proposed.

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.

Modification of a diesel generator for parallel operation with the grid
Černý, Martin ; Ctibor, Jiří (referee) ; Knobloch, Jan (advisor)
This works applies the idea of adjustment an engine-generator, so it is possible to connect an engine-generator, or other type of a generator, to the electricity. Consequently, the machine can transform the power supply without an outage. This work concerns the complex approach, provides the descriptions of particular parts, sensors and active components of a motor-generator and includes the explanation of their function. Further research is focused on designing and drawing a plan with a choice of a control unit for the whole system. Finally, the work deals with the complex implementation and testing the machine in real operation.
