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.

W artykule omówiono automatyczny systemu pomiarowy, który zastosowano w niekonwencjonalnym obwodzie energetycznym. Podstawą niekonwencjonalnego obwodu energetycznego jest układ trójzmienny, w którym silnik spalinowy o zapłonie samoczynnym jest podstawowym źródłem energii. System ten produkuje energię elektryczną i energie ciepłą na trzech poziomych termicznych. Opisany system jest niekonwencjonalny ponieważ zastosowano niekonwencjonalny obwód chłodzenia silnika spalinowego, który zaprojektowano jako termokompresor dla absorpcji ciepła z tego obwodu.

The paper deals with an automated measuring system implemented in a non-conventional energetic circuit. The basis of a non-conventional energetic circuit is a trivalent system in which the ignition combustion engine is the source of primary energy. The system produces electric and thermal energy at three thermal levels. The system is referred to as non-conventional because of the non-conventional cooling circuit of the combustion engine which has been designed as a thermo compressor for absorptive cooling circulation.

Within the framework of the basic research task funded by the Agency for support of research and development we solve a problem of a more effective non-conventional usage of the part of energy taken away by the ICE cooling system. The energy is used for production of cold. Results ofpartial solutions and methodology of energetic evaluation have been already presented in various conferences and symposia as well as published in several professional journals. This contribution brings some newly acquired theoretical and practical experience gathered during the operation of a test laboratory sample of the cooling engine in a non-conventional energetic unit. Experiments were focused on temperature mapping. The basic scheme of a non-conventional energetic unit with a cooling engine, the view of a functional laboratory sample, surface temperature in the vicinity of evaporator - taken by thermal imaging, time course of changes in the engine torque, revolutions and temperature on the engine, temperatures in the evaporator, temperatures in the liquefier, temperatures in the absorber, temperatures in the evaporator, temperatures in the VBR exchanger are presented in the paper. The results of the experiment shown that there is a 10 - 15 % agreement with the results acquired through calculations. Theoretical assumptions and solutions carried out for the alternative cooling liquid of the cooling engine in a non-conventional energetic unit can be considered real. Within the framework of this consideration a test circuit is being prepared for experiments with alternative cooler.

The paper describes a possibility of implementation of a non-conventional energetic system for ships. The described system is a source of heat at three levels, cool, refined electric energy and mechanical energy. Individual secondary energies are acquired by means of transformation of primary chemically bound energy in fuel. Primary energy is transformed by means of a combustion engine used as a driving unit of ships designed for transportation of passengers and goods. The paper contains a brief illustration of efficiency criterion by means of Carnot circulation for non-conventional system using energy and, consequently, exergy produced by means of a combustion engine. Mechanical energy can be used to drive a ship and its equipment. Exergy as a source of heat and cool for technological equipment of a ship. The implementation of a non-conventional system of a ship offers more possibilities for effective usage and increases energetic evaluation of the combustion engine in this means of transport.

The basis of a non-conventional energetic circuit is a trivalent system in which the ignition combustion engine is a source of primary energy. The system produces electric and thermal energy at tliree thermal levels. The system is referred to as non-conventional because of the non-conventional cooling circuit of the combustion engine which has been designed as a thermo compressor for absorptive cooling circulation. The paper deals with an automated measuring system implemented in the above-mentioned non-conventional energetic circuit.
