Concept of an In-line Spark-ignition Engine
Kočvara, Antonín ; Píštěk, Václav (referee) ; Drápal, Lubomír (advisor)
This thesis deals with comparison of straight four-cylinder petrol engine with a displacement of 1,5 litres and its three-cylinder alternative, which is based on a four-cylinder. The thesis starts with a research, where are examples of some currently manufactured engines. The research is followed by design of both engines, where the design of the crank mechanisms is made more in detail. After that, both crank mechanisms are subjected to dynamic analysis using FEM and MBS methods. The thesis ends with comparison of both engines in terms of crankshaft load, mass and dimensions.

Rubber torsional vibration damper for a four-cylinder diesel engine
Galásek, Martin ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
The diploma thesis ‚Rubber Torsional Vibration Damper Of a Four-Cylinder Diesel Engine‘ covers all the development phases related to a design of a rubber damper for a specified engine. The individual phases of it are discussed in details throughout the thesis. At first, the construction plan of a crankshaft is given. The computational checks for torsional vibrations and forced torsional vibration are performed then. With regards to it there might be derived the basic parameters and dimensions of a rubber torsional vibration damper. The knowledge of them enables to prepare the constructional plan of a rubber torsional vibration damper. By using this damper construction plan the torsional displacements (deviations) and forced vibrations are calculated. Finally, a mechanical and thermal stress test of this damper is performed and a crankshaft production drawing is produced.

Spark-ignition engine design for hybrid passenger car
Smejkal, Jan ; Dlugoš, Jozef (referee) ; Drápal, Lubomír (advisor)
This diploma thesis deals with design of four-cylinder spark ignition naturally aspirated engine with indirect fuel injection for hybrid passenger cars. The thesis begins with research of engines that meet the requirements of the thesis assignment. The research is followed by design of the engine, where the main components are described in detail. The last part deals with FEA analysis of the connecting rod which is followed by analytical computation of high cycle fatigue by the LSA method.
