Документ Accounting the emissions of engine fuel vapors in the criteria-based assessment of the ecological safety level of power plants with reciprocating ice exploitation process(Національний технічний університет "Харківський політехнічний інститут", 2022) Kondratenko, Olexandr Mykolayovych; Andronov, Volodymyr Anatoliyovych; Polishchuk, Tetiana Ruslanivna; Kasionkina, Natalia Dmytrivna; Krasnov, Viacheslav AnatoliyovychThis study proposed the approach and method on its basis for carrying out of the calculated assessment of the values of the comprehensive fuel and environmental criterion of Prof. I. Parsadanov as the indicator of the ecological safety level of the exploitation process of power plants with diesel reciprocating internal combustion engine, considering the mass hourly emissions of engine fuel vapor caused by the phenomena of large and small breathing of reservoirs. The purpose of the study is to develop the method for taking into account the parameters of pollutant emissions into the environment, such as motor fuel vapors due to the phenomena of large and small breathing of the power plant fuel tanks, as an independent factor of ecological safety. The calculated assessment according to the proposed method is carried out considering the properties of engine fuel, degree of a fuel tank filling, features of model of the engine operation, daily difference of atmospheric air temperature and settings of the respiratory valve of the tank. It is found that considering the emission of engine fuel vapors caused by the phenomenon of small breathing has almost no effect on the level of environmental safety, but for the option of taking into account the effect of the phenomenon of large breathing, such an effect is significant. The scientific novelty of the obtained results is that for the first time a method for considering the emission of engine fuel vapors caused by large and small breathing of fuel tanks of reciprocating internal combustion engines in complex criteria-based assessment of ecological safety. The practical value of the obtained results is that they are suitable for quantitative and qualitative assessment of the studied effects and development on this basis of technical solutions and organizational measures to reduce or eliminate them by developing appropriate environmental protection technology with actuators on a methodological basis of environmental safety management system, including the use of other steady standardized testing cycles as models of engine operation.Документ Assessment of fuel and ecological efficiency of exploitation process of reciprocating ICE of power plants with considering of emission of benzo(a)pyrene and polycyclic aromatic hydrocarbons(Національний технічний університет "Харківський політехнічний інститут", 2020) Kondratenko, Olexandr MykolayovychIn this study, the author has improved its previously proposed methods for determining the value of mass hourly emissions of benzene(a)pyrene and polycyclic aromatic hydrocarbons in diesel engine exhaust gases flow. The purpose of the study is to obtain the values of complex fuel-ecological criterion that characterize the ecological safety level of diesel engine exploitation process considering the emissions of benzo(a)pyrene and polycyclic aromatic hydrocarbons as toxic and carcinogenic pollutants. The distributions of such emissions have been obtained over the field of a 2Ch10.5/12 autotractor diesel engine operating modes field and over the modes of standardized steady testing cycle ESC. The mathematical apparatus and method of application of complex fuel-ecological criterion of Prof. Igor Par-sadanov have been improved. The author has obtained the distributions of these indicator values of ecological safety level of power plants with reciprocating ICE exploitation process over the field of 2Ch10.5/12 autotractor diesel engine operating modes of and over modes of standardized steady testing cycle ESC, as well as its average operating value. It has been established that, average operating values of Kfe criterion and the δKfe effect for all investigated variants of accounting for mass hourly emissions of B(a)P and PAH in diesel engine exhaust gas flow are almost identical and reduce the value of the Kfe criterion on 29 – 32 % – from 63 ‰ up to 42 – 45 ‰. The scientific novelty of the obtained results is that the approach of Prof. Igor Parsadanov for criteria-based assessment of fuel-ecological efficiency of autotractor diesel engines exploitation process as a part of power plant considering the of mass hourly emissions of benzo(a)pyrene and polycyclic aromatic hydrocarbons with RICE EG flow as the toxic pollutants and also methods for determining of such emissions and ponderability of such pollutants received further development towards in direction of application of this mathematical apparatus for standardized steady testing cycles.Документ Features of determination of the efficiency of devices for improvement of ecological safety level of vehicles with reciprocating ICE exploitation(Національний технічний університет "Харківський політехнічний інститут", 2019) Kondratenko, Olexandr Mykolayovych; Chernobay, Gennadiy Olexandrovych; Derkach, Juriy Fedorovych; Kovalenko, Svitlana AndriivnaThis article describes the results of analysis and numerical study of prof. I.V. Parsadanov conversion formula as the one of relevant issues of the metrological features of determination of particulate matter mass hourly emission in exhaust gases flow of reciprocating internal combustion engine on the testing bench without dilution tunnel. Purpose of the study is detection of relationship between magnitudes of cleaning efficiency coefficients of particulate matter filter of diesel reciprocating internal combustion engine for unburned hydrocarbons volume concentration in exhaust gas flow and emission of particulate matters with using of conversion formula for whole dia pason of changing of influencing factors. Object of the study is efficiency of operation of system of neutralization of legislative normalized pollutants in diesel internal combustion engine exhaust gases flow, namely particulate matter filter. Subject of the study is relationship between magnitudes of indicators that characterized object of the study which connected with each other by conversion formula. It was showed that the magnitudes of values of efficiency coefficients of operation of particulate matter filter of diesel reciprocating internal combustion engine for indicators of opacity and concentration of unburned hydrocarbons in exhaust gas which was obtained by direct measurements during bench motor tests and also mass hourly emission of particulate matter in exhaust gas flow which was obtained with using of the conversion formula, is not equal to each other for every individual operational regime of diesel engine.Calculation assessment and graphical illustration of relationship between magnitudes of this coefficients for unburned hydrocarbons volume concentration in exhaust gas flow and emission of particulate matter for whole diapason of changing of influencing factors was carried out. For the first time it was detected the differences between magnitudes of values of efficiency coefficients of particulate matter filter operation process of diesel internal combustion engine in pairs for mass hourly particulate matter emission with exhaust gases flow and opacity and toxicity of exhaust gases which connected with each other by conversion formula.
