4-stroke CI-engine Con-rod for Truck
Židek, Lukáš ; Svída, David (referee) ; Dundálek, Radim (advisor)
Brief roundup resolution of problem, tendency and new technologies. Elaboration filling proportion and ordering engine and his exploitation. Suggested proportions of con-rod and his constructive resolution with respekt on strength, functional property, production, service and lifetime. Check strength calculation con-rod eye, shank, top, connecting-rod bolt.

Comparison of traditional and nontraditional cycles of heat engines
Dobiáš, Ladislav ; Jedelský, Jan (referee) ; Štětina, Josef (advisor)
The bachelor thesis describes the thermodynamic cycles of four-stroke spark ignition (SI) and compression ignition (CI) engine, Wankel engine and two-stroke spark ignition (SI) engine. Based on the information is compared with thermal efficiency of each engines with four-stroke spark ignition engine in the T-S diagrams. There were also dedicated to Atkinson cycle and its use in practice. The last part deals with the construction of a variable compression ratio used in the development of modern engines.

Design of single-cylinder diesel engine
Němec, Jan ; Ramík, Pavel (referee) ; Píštěk, Václav (advisor)
This thesis deals with the construction of the whole combustion engine, the crankshaft design, the piston and the piston rod. It also outlines the central lubrication, the cooling, the injection pump, the movable pump and the gear pump as well as fuel filtering, injection, engine timimg, etc. The four-cycle engine has four working cycles. During the first cycle the "clean" air is drawn and the piston moves from the bottom centre to the top centre and it comes to compression in the cylinder thanks to the adjusting of the advance and the fuel is injected into the cylinder. As the piston moves rapidly to the top centre, the pressure and the temperature increase so much that the fuel ignites. The pressure is about 26 atm (2.634Mpa) and the temperature is about 600°C. The fuel burns ideally in spherical wave fronts. The fuel is injected under high pressure as aerosol generates. As the fuel expands, the volume increases and the piston moves to the bottom centre. And it is its only working cycle.The piston moves from the bottom centre to the top centre and the exhaust valve opens through which the hot gases of combustion leave - and everything repeats. The design of the particular components is shown in the animations. Modelling and simulations were produced using CAD system. Everything is supported with calculations.
