Cranktrain with High Mechanical Efficiency
Krajči, Jakub ; Raffai, Peter (referee) ; Novotný, Pavel (advisor)
This master's thesis is concerned with the mechanical efficiency of cranktrain contact pairs in a combustion engine. In the introductory part, the fundamental terminology relating to the cranktrain is presented along with the specification of the areas of mechanical losses, greasing modes and types of wear. The following chapters describe the possibilities of eliminating mechanical losses of the cranktrain and the calculation methods that can be utilized to mathematically solve mechanical losses. The practical part includes the proposal of a calculation model and its use in the analysis of the cranktrain of Skoda 1.2 HTP engine. The last part of this thesis comprises modified alternatives of the standard cranktrain focusing on the elimination of mechanical losses. The evaluation of the results is presented in the conclusion of this thesis.

Computational modeling of cranktrain mechanical losses
Smetana, Roman ; Píštěk, Václav (referee) ; Novotný, Pavel (advisor)
In the introduction of master’s thesis is introduced the common identification with basics of friction, wear and mechanical losses. Master’s thesis includes description of solving losses by help of the MBS software and analysis of mechanical losses in the crank train. In the last part of work is introduced design for decrease mechanical losses in the crank train. At the close of master’s thesis are reviewed records.
