Essay

The technology of modeling / research of the phenomena of heat generation, heat transfer, heat use in the heat engine of fast internal combustion (otto-engine), which is based on the principles of praxeology, is considered. It is noted that further development of classical approaches to modeling of work processes in the engine, relying purely or mostly on analytical and algorithmic descriptions, is almost impossible. Therefore, it is proposed to involve in the model also the real working space of the engine, systematically connecting it to the virtual, embodied in the software-algorithmic environment, and thus introducing part of reality into the model of the same reality. The desired efficiency of the model is provided by the simulation in the software environment of the interaction between themselves and the environment of the two zones into which the model working space of the engine is divided. It is in the case of two-zone interpretation of the model workspace that it becomes possible to abandon analytical control over the chemical equilibrium in the working environment and there are no reasons that would determine the material exchange between the zones.
