The paper deals with an experimental measurement of the fatigue operating life of a specimen from the aluminium AlMgSi07 alloy on a built testing equipment, into which the welded joint was implemented. An importance of the measurement is in a comparison of achieved results with the same material, which was not subjected to welding. The result of the research is verification of the influence of welding on the fatigue operating life of the concrete material at torsion stress.

The paper deals with a design of a regenerator of Stirling engine with unconventional mechanism of engine FIK. The final design of the regenerator is based on previous simulations of flowing of a working fluid, created in software Fluent. The paper presents basic requirements to be followed in the design of the regenerator. The contribution also contains a dimensional computation of the regenerator, which describes basic procedures and boundary conditions in the computation of the designed shape of the regenerator.

This paper deals with comparing three types of non-conventional mechanisms of Stirling engines. It is a wobble yoke mechanism, a special type of wobble yoke mechanism and mechanism with ring. The mechanism with a ring was designed as another possible mechanism for structural design of wobble plate in projekt Nonconventional engine FIK –Stirling. The aim is to compare the relative movement of two consecutive pistons in the Stirling engine system and thus evaluate the course compression that arises in one interconnected system of this engine. The paper deals with the dynamic simulation of these mechanisms. The dynamic simulations were made in Autodesk Inventor sofware.

the contribution deals with problems of measurement indicated pressure of internal combustion engine. Indicated pressure measurement allows better monitoring of change state quantities during implementation working cycle of internal combustion engine.
Measurement is realized with the mobile unit on the vehicle under the specified mode, the real conditions of transport, as well as on brake bench in the laboratory. By analysing the results of experiments can be more precisely to quantify efficiency of power transmission and energy flows in the drive mechanism of the vehicle.
