Development of an internal combustion engine selection method on the basis of heat exchange conditions evaluation at modernization and repairs of energy-transforming objects

The problem of raising efficiency of power plants with internal combustion engines has been analyzed in the article. Comparative analysis of internal combustion engines has been carried out. Energy conversion in internal combustion engines is one of the most energy consuming systems. Efficiency increase of this system is considered with due regard to both the design parameters of a diesel engine and its operating conditions, making it possible to work out more reliable and objective methods of minimizing consumption of natural and energy resources in power plants. Comparative analysis of the existing methods of evaluation as well as of internal combustion engines models were performed with due regard to all the limitations. on its basis the principal drawbacks and imitations of those methods as well as types of engines were determined. It has been decided that in spite of plenty of investigations on the internal combustion engines the problem of selecting a proper engine type it has not been solved yet and solved and further investigations are required. A method of specifying an internal combustion engine type on the basis of descriptive forecasting model was suggested. Such models are compiled by processing of statistic investigations results. The main tendency of development be-comes evident, it being the most important result of this investigation and making it possible to increase the efficiency of these processes. The developed method makes it possible to specify internal combustion engines with optimal parameters, taking into account the heat transfer conditions at modernization or repairs of energy transforming objects. Implementation of this method simplifies evaluation and selection of diesel engines at modernization and repairs that results in energy and resources saving and ensures optimal conditions for technological processes
