Spark-ignition engine for small autonomous devices
Horák, Vojtěch ; Beran, Martin (referee) ; Svída, David (advisor)
The thesis deals with the design of a small-volume four-stroke internal combustion engine with a maximum displacement of 10 cc and a power of 1 kW for autonomous devices of smaller dimensions. In addition to the analysis of individual propulsions for small aircraft, there is also a chapter with the comparison of an internal combustion engine and an electric motor with similar power. Another part of the work is the creation of a thermodynamic model in the GT Power program and its subsequent optimization to increase the overall efficiency of the engine.
Design of the condensation separator unit for water injection system for spark ignition engine
Burjeta, Michal ; Beran, Martin (referee) ; Bazala, Jiří (advisor)
Tato práce je zaměřena na systém vodního vstřikování a způsoby zajištění dostatečného množství potřebné kapaliny pro správný chod tohoto systému. Jedním zajímavým a nezávislým řešením je využití odpadních produktů motoru, a to vodní páry produkované spalováním paliva. Pro zajištění kondenzace je nutné zchlazení výfukových plynů pod rosný bod páry, což lze zajistit opatřením výfukového potrubí chladiči. Vzniklý kondenzát je pak potřeba efektivně oddělit od proudu plynů a zachytit. Návrh takovéhoto systému vychází z reálně naměřených dat a jeho následným ověřením pomocí CFD simulace.
Remote diagnostics of the combustion engine in real time
Jobánek, Vojtěch ; Beran, Martin (referee) ; Svída, David (advisor)
There is a current trend of constantly increasing emphasis on the cost-effective operation of vehicles in freight and passenger transportation. One of the efforts is to reduce the unproductive time of the driver and the vehicle which is spent on maintenance and repairs. The unproductive time can be significantly minimized by well-timed and faultless diagnostics that is, ideally, without need for a service visit. Real-time remote diagnostics, including an application that evaluates the current state of the vehicle, is a modern tool for efficient use of the vehicle.
Camshaft design for Miller cycle engine
Dúlovcová, Gabriela ; Beran, Martin (referee) ; Svída, David (advisor)
The main aim of this thesis is the analysis of influence of inlet valve opening length and compression ratio on performance and thermodynamic parameters of Miller cycle using GT-SUITE software. Next step was an optimization of inlet and exhaust valve timing with goal of increasing motor effective power. For chosen option was designed cam shaft with regard of kinematic and dynamic magnitude courses.
The potential of biofuels for modern internal combustion engines
Matyáš, Milan ; Bazala, Jiří (referee) ; Beran, Martin (advisor)
The aim of the bachelor thesis is to map the potential use of biofuels for modern piston internal combustion engines. The thesis deals with both reducing the environmental impact and a possible increase in performance parameters and engine efficiency such as the use of fuel with increased anti-knock resistance in spark ignition engines.
Automatic Estimation of Distance between Vehicles
Beran, Martin ; Špaňhel, Jakub (referee) ; Sochor, Jakub (advisor)
This thesis deals with the automatic estimation of distance between moving vehicles. The resulting files contain edited video showing the distance. The solution is implemented in C++.
Electronic Mail Room of the BUT
Beran, Martin ; Křena, Bohuslav (referee) ; Marušinec, Jaromír (advisor)
This dissertation thesis attends to problems of electronic registry for VUT. It deals with the principal of electronic registry functioning, electronic signature and it compares offer of the commercial registries. It goes in for the proposal and implementation of the electronic registry for VUT. Since the using of the e- registry on all public service Office was legalized the people can avoid long queues and the employees are avoided from the stress before dead lines. By the communication through the electronic registry is very important the electronical signature. It is almost a full-valued and lawful alternative to the physical signature. For its safety and utility this system employes asymmetric codes and hash algorithm. Presently in many states, where the electronical signature is legalized it is used together with standard X 509 which defines the format of certificates, organization and action of certification authorities. The certification autority ensures safe connection of the person and general key for using of the electronical signature.
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
