This paper contains results of mathematical modeling connected with non-conventional energetic system using the cooling combustion engine (the engine cooling circle is the ejector of absorption cooling). We especially have focused on the influence of a more intensive cooling on the engine ecological parameters. The paper is a continuation of previous publications and focuses on the results of the designed mathematical model of particulate matter formation and its experimental verification under extreme intercooling. Our previous achievements were already presented on scientific conferences and in professional journals.
