Temperature distribution of rubber damper of gasoline engine
Knor, Pavel ; Ramík, Pavel (referee) ; Píštěk, Václav (advisor)
The main aim of this master’s thesis is to design the drivetrain of four-cylinder gasoline internal combustion engine with torsional vibration rubber dumper. For the basic parameters of the engine are designed two optional crankshafts. Crankshaft with eight counterweights and crankshaft with four counterweights. The thesis also includes modal analysis of the crankshaft using FEM, and design of the main dimensions of the dumper. The following part describes the calculation of force torsional vibration and safety factor solution of crankshaft fatigue using FEM. The final calculation is of the temperature field in the rubber dumper in selected operating modes.

Three-cylinder in-line gasoline engine
Balash, Ievgen ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
The main aim of this master’s thesis is to design the powertrain of turbocharged threecylinder in-line gasoline engine based on given parameters. The work introduces three variants of balancing of inertia moment of rotating masses and balancer unit of first order moment of inertia of reciprocating parts. The thesis also presents calculation of torsion vibration of the powertrain and structural design of the rubber damper. In conclusion a stress analysis of the crankshaft is submitted with and without torsion vibration damper.
