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.
Engine Control Units for 6-cylinder Diesel Engines
Florek, Matej ; Beran, Martin (referee) ; Svída, David (advisor)
This thesis is focused on diesel combustion engines, their history and technical development. It describes the working principle of 4-stroke process and components of the engine. After that, it brings the overwiev of the fuel injecton systems development and the types that are used nowadays. Then it comes to electronic control unit, its significance and role in fuel injection process. The last part indicate a couple of commercial electronic control units which are currently used for managing 6-cylinder diesel engines.
Exhaust Manifold for 600ccm Engine
Řezáč, Vojtěch ; Beran, Martin (referee) ; Svída, David (advisor)
In this bachelor’s thesis I am comparing affect of different exhaust mufflers on parameters of Yamaha FZ6 Fazer’s motorcycle engine. I am focusing on power, torque, volumetric efficiency, brake measure effective pressure and brake-specific fuel consumption. Theese data were taken from simulations made in special software. Theese parameters are measured for three types of exhaust mufflers, original, tuned by Devil company with catalytic converter and without catalytic converter. Result of this thesis is to compare simulated data for two types of motorcycle riders, one who prefers touring style of riding and for one who prefers sport style of riding
Knock detection and analysis
Melichárek, Patrik ; Svída, David (referee) ; Beran, Martin (advisor)
This thesis focuses on knocking combustion. First part of this thesis focuses on recherche of this topic, where is a brief comparison of normal and knocking combustion, introduction of factors that have impact on occurrence of knocking and discusses methods of knocking detection. It is followed by description of negative effects of knocking combustion and modern methods of its prevention. Second part consists of measurements to prove credibility of theoretical basis of the topic.
Electronic speed controller
Šimbera, Michal ; Kučera, Pavel (referee) ; Svída, David (advisor)
The thesis deals with the design, realisation and functional verification of an electronic cruise control unit. Required inputs, outputs and controller of the control unit are identified first. The design and layout of the electronical components, including the processor, power supply and other necessary hardware is discussed. The algorithm for the control unit is developed in C/C++ and thoroughly analysed. The functionality of the cruise control unit equipped with the algorithm is verified through a case study performed on a combustion engine.
Concept of the aircraft CNG engine
Šmerda, Ondřej ; Beran, Martin (referee) ; Svída, David (advisor)
Master’s thesis deals with comparsion and rating the compressed natural gas as an aircraft piston engine fuel. An information search of conventional fuels and differences of the fuel systems for AVGAS and CNG is included. Next part describes the aircraft and its engine on which is the mathematic model based. After that perfomance and consumption data are calculated for both fuels and the results are then compared. At the end of the thesis, a design of the CNG fuel system with components selection is described.
Testing Stand for Fuel Injection Units
Rytina, Matěj ; Beran, Martin (referee) ; Svída, David (advisor)
Master’s thesis is focused on construction of testing stand for unit injector system mounted in Iveco Trakker engines. Testing stand can be with appropriate changes used for testing wide variates of unit injector systems. Simulation of computational model was computed in GT Suite software. Stress strength analysis was computed in Ansys Workbench 18.1 software.
Automotive fuels and their future in green transport
Mrázková, Kristýna ; Svída, David (referee) ; Beran, Martin (advisor)
This bachelor thesis deals with the problematic of currently most used automotive fuels and their impact on the environment. It briefly describes the development of combustion engines and provides an overview of most common automotive propulsions and their alternatives. The final chapter of the thesis deals with the problematics from socially political perspective.
Issues of legislative tests in the assessment of exhaust pollutants
Weidenhöfer, Jan ; Svída, David (referee) ; Beran, Martin (advisor)
This work deals with issues of emissions in passenger cars with a focus on legislative tests in the European Union. At first, the reader is briefly informed about the historical context and current legislative requirements for modern passenger cars in Europe and other parts of the world. The following section is devoted to the NEDC driving test, with special emphasis on describing and evaluating the methods by which manufacturers have been able to artificially reduce their car emissions. The main part of the thesis are chapters devoted to newly introduced measurement using global WLTP methodology and especially measurements in real operation RDE. An important part of these chapters is the analysis of advantages and disadvantages of new methodologies and the problems of their implementation.
Problematics of ecological transport of passenger cars
Španko, Dominik ; Svída, David (referee) ; Beran, Martin (advisor)
This bachelor thesis deals with the problematics of ecological transport of passenger vehicles. The aim of the thesis is to analyze given issue and evaluate negative effects caused by passenger vehicles. In the introduction are presented the most widely used types of vehicles, later on are evaluated facts that influence the environmental impact of given vehicles throughout their entire life cycle. In the last part of thesis, the ecological burden of passenger vehicles with combustion engine is compared to electric vehicles, also possible future development in given issue is outlined.
