CRITERIA-BASED ASSESSMENT OF FUEL AND ECOLOGICAL EFFICIENCY OF EXPLOITATION PROCESS OF RECIPROCATING ICE OF POWER PLANTS CONSIDERING OF EMISSION OF SULFUR OXIDES

In the calculation method and mathematical apparatus for assessment of the complex fuel and ecological criterion of Prof. Igor Parsadanov has been improved by considering the mass hourly emissions of sulfur oxides with the exhaust gases flow from the reciprocating ICE as a toxic pollutant. The purpose of the study is obtaining the values of complex fuel-ecological criterion that characterize the ecological safety level of diesel engine exploitation process considering the emissions of sulfur oxides as a toxic pollutant. The European Steady Cycle (according to UENCE Regulations № 49) was used as the exploitation model. A set of initial data has been obtained for the calculated criteria-based assessment of the ecological safety level of the exploitation process of power plants with a reciprocating ICE on the example of the autotractor diesel engine 2Ch10.5/12 based on the results of data processing of bench motor tests. The calculated assessment of specified criterion values considering sulfur oxides emissions was carried out. It has been detected that the value of the fuel-ecological criterion for the basic variant of considering the emissions of sulfur oxides, i.e. considering the values of sulfur content in motor fuels and oils and burning oil consumption, typical for diesel 2Ch10.5/12, differs for the variant that does not take into account this ecological safety factor, on average by 6.6 %. For the option that takes into account the modern requirements for the sulfur content in technical fluids and the technical level of modern reciprocating ICE, this difference is 0.5 %. The identified dependences are described by formulas by the method of least squares. The scientific novelty of the obtained results is that the approach of Prof. Igor Parsadanov received further development for criteria-based assessment of fuel-ecological efficiency of autotractor diesel engines exploitation process as a part of power plant considering the mass hourly emissions of fulfur oxides with RICE EG flow as the toxic pollutants and also methods for determination of such emissions and ponderability of such pollutants in direction of application of this mathematical apparatus for standardized steady testing cycles.
