The five-cylinder inline diesel engine with eccentric crank mechanism
Süttő, Daniel ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
The aim of this thesis is to find out the influence of eccentricity of crank mechanism on the duration of the force between the piston and the cylinder liner. At the same time I wanted to find out its influence on the balance of the whole system. It is important to design the balance for the selected value of the eccentricity and subsequently put through the crank shaft to stress analysis with torsional vibrations. I got so interested in this problem that in addition to the whole topic I designed a torsional vibration damper.

Four-cylinder petrol engine with eccentric crank mechanism for passenger vehicles
Mlčoch, Pavel ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
This Diploma Thesis is aimed at exploring the potential of offset crankshaft mechanism for four cylinder inline petrol engine in terms of reducing the frictional losses of the piston group. Thesis deals with the influence of eccentricity on kinematics, dynamics and balance of the crank train. Furthermore, specific crankshaft balancing is elaborated and applied on 3D CAD model of the crankshaft. Calculation of fatigue safety factor using the advanced LSA method that takes into consideration the effect of forced torsional vibration and utilizes outputs from the FEA software (ANSYS APDL) is performed as well. Thesis also includes design of two options of rubber torsion damper mounted on the engine belt pulley and the follow-up choosing of the more advisable one.
