Thermal Activation of the Combustion Chamber of a Reciprocating Internal Combustion Engine

The dominant feature of the work of many specialists on the design of the internal combustion engine is to achieve the possible lowest fuel consumption, which is the most convenient measure of the efficiency of the thermodynamic cycle. From the very beginning of this heat machine, there are many of solutions that are better or worse fit to the global development trend. In this paper, the authors suggest the possibility closer to the optimal solution by introducing structural active zones, where the task is instantaneous (during one cycle) heat transfer to the skin layer on elements of the combustion chamber and to transfer part of the recovered heat to the next cycle, reaching a growth effect of the useful efficiency by 10% to 20%. The solution is different from the ones used by the fact that it is only partially insulating barrier, and the main goal is focused on supporting the next thermal cycle by which it is possible to affect as mentioned above. This paper describes the idea of the functioning of the active combustion chamber and pointed out the technical capabilities of its creation.
