Article discusses about the use of heat exchangers for stationary combustion engines and cogeneration units. The paper is dedicated to the problem of unused thermal energy in stationary engines. It analyses possibilities of accumulation of heat energy and its possible application in various fields. The paper deals with the classification of heat exchangers and with the subsequent description of design solutions of heat exchangers types used in given field. Resolves draft of exhaust gas heat exchanger according to the required parameters of internal combustion engine and subsequent simulation in the simulation program Comsol multiphysics to verify the correctness of the design and the construction solution of the exhaust gas heat exchanger for stationary combustion engines.

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.

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.
