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.

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.

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.

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.

Injection System with Pressure Accumulator for Commercial Powertrain Units
Suchánek, David ; Prokop, Aleš (referee) ; Dundálek, Radim (advisor)
The present work deals with a common-rail fuel injection system for powertrain applications. As part of the solution of the thesis, a comprehensive analysis of the injection system has been carried out with an indication of the principle and function of the necessary components, including demonstrations on specific vehicles and an outline of future developments. The injection system can be divided into 3 parts: low pressure, high pressure and control. The low-pressure section describes the fuel filter and feed pump. Within the high-pressure part, the components which are the injector, the high-pressure pump and the fuel rail are given in context. The control section then presents the control unit, sensors and actuators necessary to control the pressure and quantity of fuel. In order to give a comprehensive overview of the common-rail fuel injection system, the common-rail system parameters were measured and evaluated on a specific power unit using diagnostic equipment. The measurements verified the maximum pressure declared by the vehicle manufacturer, while showing the fuel pressure waveform in the fuel rail in different engine operating modes. style.
