The Cylinders of Four-stroke Engines
Vanda, Marek ; Řehák, Kamil (referee) ; Dlugoš, Jozef (advisor)
The topic of this bachelor thesis is Cylinders of Four-stroke Engines. First part is about four-stroke cycle, engine construction. Next parts are about cylinders, their function and requirements. Also included is the importance of the cylinders on the engine operation and engine life. Last part is focused on the construction, materials of the cylinders and their usage in the past and today.

Evaluation of mechanical and structural properties of new block
Lefner, Jiří ; Nová, Iva (referee) ; Čech, Jaroslav (advisor)
The purpose of this dilploma thesis is to evaluate mechanical and structural properties of two types casts of Al-alloy (components of the engine block) which were made by different technologies. Die casting with local squeeze casting and without local squeeze casting. First of them is used in lot manufacture of the current engine block. The aim of the foundry is to change the technology and start to produce new block by the die casting without local squeeze casting. The samples were taken from the both parts (lower and upper part) of the current and the new engine block which are made in foundry of Skoda Auto a.c. in Mladá Boleslav. Sets of mechanical and structural properties were selected, evaluated and tested by statistical programs. It was used fifty casts of the engine blocks for the experiment.
