Electric vehicle charging solutions in apartment complexes
Machajdík, Marek ; Poulíček, Matěj (referee) ; Štětina, Josef (advisor)
In the work, public charging stations are classified, their description is given, and is added information about the compatibility of charging stations with current electric cars. Information of individual electric car charging using wallboxes is summarized and their characteristic features and power limits are listed. Considerable attention is paid to V2B technology and the possibilities of charging electric cars in multi-unit apartment buildings with their own parking space. The work will also include a file used to calculate a suitable solution for charging electric cars in an apartment building. The final part of the work is devoted to the solution of charging electric cars for a specific apartment building using the created calculation file.
Thermodynamic 1-D model of the turbocharger of an internal combustion engine
Mrázková, Kristýna ; Böhm, Michael (referee) ; Štětina, Josef (advisor)
Master thesis deals with 1D heat transfer simulation of turbine housing laying emphasis on temperature of exhaust gas leaving the turbine. The thesis covers construction and thermodynamics of turbochargers, exhaust gas aftertreatment and heat transfer simulation software. Then the thesis focuses on exploring turbine housing 3D model discretization, building physical turbocharger model for 1D simulation of exhaust gas output temperature and heat transfer through turbine housing. Heat transfer coefficients were calibrated for transient simulation predicting temperature of output exhaust gas in compliance with NEDC cycle. Results analysis and optimization follow, a suggestion on model integration into the virtual turbocharger system is also included.

Predicting spark-ignition engine emissions
Jirout, Petr ; Böhm, Michael (referee) ; Štětina, Josef (advisor)
This diploma thesis deals with the possibility of predicting emissions of SI engines. The aim was to create an algorithm for predicting unburned hydrocarbons and carbon monoxide, based on ECU signals. The algorithm is based on practical experiments with SI engines. In the summary, the issues and the possible use of the created algorithm following the incorporation of EU7 are outlined.
Refrigeration systems in the food industry
Dvořák, Josef ; Katolický, Jaroslav (referee) ; Štětina, Josef (advisor)
Bachelor´s thesis is aimed at refrigeration systems in the industry which are used mainly in the food industry. Here are described individual parts that are refrigeration systems assembled. The work also contains summary of the ways you can make use of waste heat and also factors that have impact on economy of operation. The aim of work is to describe the basic analysis of thermodynamic cycles in the refrigeration systems which are displayed on the illustrative diagrams.
Trends in the development of hybrid vehicles
Ďurica, Matej ; Tobiáš, Martin (referee) ; Štětina, Josef (advisor)
This bachelor thesis is dedicated to make brief research in the hybrid automotive department, focused on the last ten years of development. The first part describes the categories of hybrid vehicles with an emphasis on the development of accumulators and related technology. An important part is the advantages and disadvantages of systems and drives. The second part deals with the future of hybrid drives, applications mainly in heavy industry, and the possibilities of changing "heavy" fossil fuels with "greener" alternatives. At the end of the work is the evaluation of the impact of the COVID crisis on the automotive industry.
A demonstration lab for building ventilation
Kundrát, Roman ; Štětina, Josef (referee) ; Charvát, Pavel (advisor)
Objective of this thesis is the design of ventilation system for demonstration laboratory. Based on literature studies, experience and advice of experts is at work introduced the concept of design of ventilation equipment for laboratory, which will serve to demonstrate the air inlet into the room using different diffusers. Introduction of distribution elements for ventilation, priors the actual design of laboratory.
Airflow inside of a passenger car
Bělka, Miloslav ; Štětina, Josef (referee) ; Charvát, Pavel (advisor)
This bachelor thesis deals with hearting, air-conditioning, air distribution and airflow in a cabin of a passenger car. Ventilation of the cabin is needed for acceptable level of indoor air quality. The air supplied into the cabin is conditioned by heating or air conditioning system in order to achieve an appropriate level of thermal comfort of the passengers. Various arrangements of automotive heating and air-conditioning systems are described in the thesis. The thesis also includes the description and results of a set of measurements of air temperatures and air velocities inside of a passenger car cabin.
Emission standards for IC-engine vehicles and emission test systems
Náhlík, Tomáš ; Pech, Ondřej (referee) ; Štětina, Josef (advisor)
This bachelor thesis deals with the issue of emission standards and emission measurements with contemporary motor vehicles. Introduction acquaints reader with the reason it is actually necessary to address this issue and what are the main negative components of emissions by motor vehicles. Effects of such components on human health and the environment are also included. List of historic and of course current emission standards both from within the European Union and globally follows. The thesis concludes with an overview of analytic methods, tests and test techniques focused on emissions by motor vehicles.
Comparison of Hybrid Powertrain Topologies in Daily Commuting Regime
Ušiak, Michal ; Štětina, Josef (referee) ; Vondrák, Adam (advisor)
The master’s thesis deals with modelling of various architectures of hybrid powertrains for three vehicle sizes in GT-SUITE and compares them in daily commuting operating mode. On top of making of the hybrid vehicle simulation models, control algorithms had to be created to manage the energy split between the internal combustion engine and the electric motor for each of the architectures. Routes to work and back were logged using the GPS and postprocessed to obtain the speed and the road grade profiles. Resulting data was used as an input in simulations of daily commuting. To compare all hybrid powertrain architectures, fuel economy and electricity consumption were evaluated for WLTP and daily commuting operating modes. Finally, the environmental impact of each topology was assessed based on an estimation of corresponding well-to-wheel emissions.
