Design of Device for O-rings Fitting on Overflow Valve of Injection Pump
Matula, David ; Beran, Martin (referee) ; Ramík, Pavel (advisor)
The thesis deals with the problem of threading o-rings on the overflow valve of the CP4 injection pump. The thesis was prepared for the company Bosch Diesel s.r.o. in Jihlava. In the thesis, first of all, an introduction of the company and their products is given. In the next part of the thesis, an analysis of the current state of the workplace is made. This is followed by market research in the field of automated o-ring threading. This research served as inspiration for the design of the threading head. The constructed head was manufactured and tested at the test site. After testing the head, several variations of the o-ring threading station were developed. A multi-criteria method was used to select the most suitable variant. A design concept of the workstation was developed for the winning variant. The resulting concept was evaluated from an economic and technical point of view.

Exhaust Manifold for Formula Student Engine
Bartoš, Tomáš ; Beran, Martin (referee) ; Svída, David (advisor)
The aim of this diploma thesis is the design and tuning of the exhaust manifold and muffler for the Formula Student car. The single cylinder atmospheric spark ignition engine Husaberg FE 570 is used as a powertrain unit. The exhaust system is designed according to the Formula Student rules. To design the exhaust system has been used as theoretical knowledge as well as software Lotus Engine Simulation.

Transition State Simulation of Combustion Engine
Forbelský, Antonín ; Beran, Martin (referee) ; Svída, David (advisor)
Master's thesis focuses on the simulation engine transients. The model of single-cylinder engine was constructed in simulation software Lotus Engine Simulation. Then was made simulation of transients. The thesis try to describe the influence of moment of inertia of the engine, the engine starting speed and process of throttle opening during the transients. For all modes also compare two methods of fuel control.

Intake Manifold for 140kW CNG Engine
Wojcik, Rudolf ; Beran, Martin (referee) ; Svída, David (advisor)
The master´s thesis is focused on the design of the multi-point CNG injection for the VW 1.4 TSI intake manifold turbocharged spark ignited engine. The 3D model that was created using Autodesk Inventor Professional 2012 is based on the real intake manifold. This model served as an input for CFD analyses of mixing CNG with air. These were made in STAR-CCM+ software.

Aerodynamic components of Formula 1 vehicles
Mazáč, Petr ; Beran, Martin (referee) ; Vančura, Jan (advisor)
This bachelor’s thesis deals with research themed aerodynamic components of Formula 1 vehicles. The beginning of the thesis is focused on basic of aerodynamic and generating downforce. Afterwards it deals with developement of aerodynamic from the beginning of Formula 1 to the present time, followed by categorization of the various aerodynamic elements which were used on vehicles throughout the history of the sport and in the present time with their construction description. It also summarizes active aerodynamic components.

Indication apparatus installation for a diesel engine
Slávik, Andrej ; Ramík, Pavel (referee) ; Beran, Martin (advisor)
The issue of measuring combustion pressure has been a part of internal combustion engines since their inception. The measurement evaluates the course of pressure as a function of volume change. This dependence is plotted in indicator diagrams. Other parameters are evaluated directly, such as combustion noise, but also indirectly, i.e. by calculation from the values of indicator diagrams. Measurements can be performed with different types of sensors. However, these sensors must be properly positioned to measure the correct values. For a given motor with a problematic sensor location, a suitable sensor is selected using calculations. The engine cylinder head is processed by reverse engineering methods. According to the acquired knowledge and available solutions, two variants of piezoelectric sensor placement are proposed with the recommended use of variant no.1.

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.
