The High Pressure Fuel System Application for CI-engine
Ševčík, Ondřej ; Prokop, Aleš (referee) ; Dundálek, Radim (advisor)
This thesis focuses on the design of new high pressure injection system application on diesel engine. The design came from company Zetor’s demands. For this application was chosen system Common Rail supplied by company Bosch. Assignment was separated into several tasks. Research of suitable components for low pressure section, design of waste system and high pressure injection tubes design including injector clamping. Due to injectors used in this system was necessary to redesign cover for valves and even new system to lead wires from outside of the engine to injectors. Injector is attached by screw connection, which is composed from screw and clamping jaw. These parts are subjected to an analytic calculations. Clamping jaw of injector is even subjected to a FEM analysis, which focuses on fatigue life. Finally, the drawings were documented.

Zeroshifting Transmission Mechanism Design
Mičola, Ivo ; Prokop, Aleš (referee) ; Svída, David (advisor)
This thesis deals with no delay gear shifting. The first part is devoted to theoretical introduction. The next part describes comprehensive approach to vehicle dynamics, the choice of gear ratios, the use of reverse engineering to model the interior of the gear housing and the actual structural design of the internal components and strength analysis. Moreover, this work should fill the gap in the available literature which is publicly accessible.

Increase of Charging Efficiency of 140kW CNG Engine
Hadrava, Martin ; Vančura, Jan (referee) ; Svída, David (advisor)
The master’s thesis is focused on flow analysis work filling in turbocharged CNG engine. The research method is reverse engineering. The intake canal is casted and than scanned by 3D Scanner ATOS. The CAD model is created in program Creo Parametric 2.0. In the created interactive model is simulated flow in the CFD program Star CCM +. The air intake system is modified for increasing the charging efficiency of the engine.

Six cylinder diesel engine for commercial vehicles
Pulava, Oleksandr ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
The aim of this diploma is to design a crankshaft for a six-cylinder commercial vehicle, which is one of the unified motors. The main parts are the design of the crankshaft configuration, the crankshaft balancing method for forces and moments, the crankshaft design documentation, and the crankshaft strength verification. The design of torsional vibration damping characteristics is also made and its effect on torsional vibration and crankshaft strength is determined.
