Diagnostika a opravy systému Common Rail
VASTL, Tomáš
This bachelor thesis deals with the common-rail system. It focuses on serial and parallel diagnostics on a specific Ford vehicle. The introductory part is focused on system theory, diagnostic methods and its importance. The following section addresses a specific issue with a focus on a specific defect in the vehicle. In the practical part of the work, individual measurements are performed by serial and parallel diagnostics on the vehicle.

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.

Computational model of an CR diesel combustion engine
Kučera, Vlastimil ; Beran, Martin (referee) ; Svída, David (advisor)
Combustion-engine control is one of the most important parts of engine application and has a direct impact on its characteristics. Diploma thesis shows the preparation of a test engine and its installation to test cell. It describes measurement and data post processing necessary for common-rail diesel engine control and their application in the creation of a mathematic model in GT-SUITE.

Praktické měření a diagnostika systému Common-rail
HART, Petr
This diploma thesis deals with practical measurement and diagnostics on chosen Hyundai Santa Fe vehicle and on the training panel. The thesis is divided into two parts. The first part is to familiarize the reader with the fuel system of the diesel engine with the common-rail pressure magazine, with the concept of serial and parallel diagnostics. In the second part, the diplomat performs serial and parallel diagnostics of the diesel engine fuel system on the vehicle and on the training panel. The diplomant will further describe the measured data and evaluate the differences in the measurements.

Measurement Panel Common-rail
HART, Petr
This diploma thesis deals with practical measurements on the fuel system of the diesel engine system Common rail. The thesis is divided into tvo basic parts. The first part is theoretical and has the task to familiarize the reader with the history of the diesel injection until after the system Common-rail, where the principle and part of this system will be explained. The second part is focused on the possibility of practical measurement to the fuel system Common-rail on the tutorial panel. Measurement tasks for students will be created on the basis of practical measurements, including the sample assignment, and the elaboration of the form of the protocol. Verification tasks on students and the evaluation of the thesis work will be carried out in the conclusion.

The High Pressure Fuel System for CI-engine
Strouhal, Pavel ; Prokop, Aleš (referee) ; Dundálek, Radim (advisor)
This diploma thesis is focused on examining the development of a diesel tractor engine with a newer injection system, concretely common-rail system. Mainly it is about the application of the high pressure fuel pump, fuel rail and injectors. With regard to the used components are appropriate adjustments made on the engine, and then checked using the available calculations. Brief mention is given to the theoretical summary of the contemporary state of applied injection system and its development trend. Selecting adjustments is primarily based on observed operating load. However, it is also striving to their simplest implementation. An integral part of this work is drawing documentation of newly designed components.

Application of Pressure Accumulator Injection System on CI Engine
Šiška, Adam ; Štěpánek, Karel (referee) ; Dundálek, Radim (advisor)
This master’s thesis deals with building the most modern injection systém Common-Rail for four-cylinder tractor diesel engine. The following application is a conversion from a obsolete system with inline injection pumps. Because the costs for this conversion must be minimized, that it is effort of minimal intervention in engine design. First this master’s thesis focuses on the theory of injection systems of diesel engines and related things and then the thesis shows the design conversion supported analytical calculations and FEM analysis of newly designed components.

Common-rail System for 4-cylinder CI-engine
Ošmera, Petr ; Svída, David (referee) ; Dundálek, Radim (advisor)
This diploma thesis with a view to „common rail system for 4-cylinder CI-engine“ deals with the application of modern injection system „common rail“ to already existing compression-ignition tractor engine. The diploma thesis treats of the most necessary adjustments related with the replacement of injection systems which was solved in the way of the minimum adjustments. This kind of solution deals with an economic aspect of the problem. The reconstruction contains the engineering design of development of high pressure components and the suitability of their placing on engine.The primary adjustment of the application of system „common rail“ for existing tractor engine confirmed the possibility of this reconstruction.

Passenger Vehicles Drive Unit Recent Development
Sedlář, Martin ; Svída, David (referee) ; Beran, Martin (advisor)
This bachelor’s thesis is an overview of modern drive units trends. The first part of this thesis demonstrates combusting engines sorting; the next main part is an overview of a few drive units which are characteristic for their categories. There is a comparison of two lower power class engine representatives and two higher power class representatives in final chapter. The conclusion summarizes described topic and expresses own opinion.
