Powertrain of in-line five-cylinder spark ignition engine
Hájek, Daniel ; Rauscher, Jaroslav (referee) ; Píštěk, Václav (advisor)
Objective of bachelor’s thesis is, for noted geometric, thermodynamic and operation parameters cylindrical unit of five-cylinder spark-ignition engine, perform calculation of thermodynamic cycle, project basic proportion of piston group and for noted operation modes perform strength check of connecting-rod eye. Rated value verify, if corresponded with true value of spark-ignition engine. In preamble is stated basic use of spark-ignition engines, their operation principle and design concept. The bachelor’s thesis is consists from description of calculation and supplement, where is calculation done. The calculation is consists from three parts. The first part is calculation of thermodynamic cycle, in the second part are calculated forces reacting to piston group and third part is strength calculation and check of connecting-rod eye. In the last part is results evaluation of calculation, show a methods of calculation and a new trends spark-ignition engine of evolution.

Crank mechanism of in-line three-cylinder diesel engine
Cetkovský, Martin ; Rauscher, Jaroslav (referee) ; Píštěk, Václav (advisor)
Objective bachelor’s thesis, which will be achived is, for scheduled elementary geometric, thermodynamic and operation parameters cylindrical unit of in-line three-cylinder diesel engine, perform calculation of thermodynamic cycle, design elementary dimensions of piston group and for schedule operation modes perform strength check of connecting-rod eye. Consequently rating value compare with value of real true diesel engine. In introduction is explained basic principle of diesel engine and their design concept. The bachelor’s thesis is consisted of description of calculation and supplement, where the calculation is done. The calculation is accomplished in three parts. Thermodynamic cycle is solved in the first part. Forces acting on piston group are solved in the second part and strength calculation and check of connecting-rod eye is solved in the third part. The end is focused on evaluation of calculation and recent solution of diesel engine.

The present state and development trends of tractors.
Valach, Přemysl ; Píštěk, Václav (referee) ; Rauscher, Jaroslav (advisor)
Přemysl Valach The present state and development trends of tractors. The aim this Bachelor thesis is to summarize the contemporary states of internal combustion engines in tractors and requirements on them. The overview of internal combustion engines was made and it also constains a brief characteristics and descriptions of these engines. At the end of this work there is a description of historical development and there are olso mentioned trends for the future.

Powertrain of in-line four-cylinder spark ignition engine
Mačuga, Martin ; Rauscher, Jaroslav (referee) ; Píštěk, Václav (advisor)
According to given to cylinder diameter, stroke and ideal indicator diagram we will investigate with maximum cylinder pressure and further design for proportions piston insider ( piston and piston - pin) as well as piston rod. Then shall do strength calculation upper connecting-rod eye according to given to calculations namely for the select material of piston rod. In the end we evaluate the select material whether is for suggested piston rod fit.

Powertrain of experimental single-cylinder spark ignition engine
Číp, Tomáš ; Rauscher, Jaroslav (referee) ; Píštěk, Václav (advisor)
Objective of bachelor’s thesis is, for noted geometric, thermodynamic and operation parameters cylindrical unit of experimental single-cylinder spark ignition engine, perform calculation of thermodynamic cycle, project basic proportion of piston group and for noted operation modes perform strength check of connecting-rod eye. In preamble is stated basic use of spark -ignition engines, their operation principle and basic fisson. The bachelor’s thesis is consists from of calculation, which is continuously described.The calculation is consists from four parts. The first part is calculation of thermodynamic cycle, in the second part are calculated concept piston group, in next part are calculated forces reacting to piston group and fourth part is strength calculation and check of connecting-rod eye. In the last part is results evaluation of calculation.

The present state and development trends of engines for motorcycles
Peňáz, Jan ; Píštěk, Václav (referee) ; Rauscher, Jaroslav (advisor)
This bachelor thesis describes the actual situation of construction solutions of small motorcycles engines. And then this thesis compares power and economic parameters of these engines.The thesis shows watched parameters in the diagrams and in the tables. From this we deduce the direction which the small motorbikes engines take. In the conclusion we summarize the main development tendencies and trends for the future
