    This 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.

    Determination of reference values of complex fuel and ecological criterion as the separate independent factor of ecological safety
    (Національний технічний університет "Харківський політехнічний інститут", 2021) Kondratenko, Olexandr Mykolayovych; Andronov, Volodymyr Anatoliyovych; Koloskov, Volodymyr Yuriyovych; Tkachenko, Olexandra Olexandrivna; Kapinos, Yelyzaveta Volodymyrivna
    In this study the approach and method on its basis for calculated assessment of reference values of complex fuel-ecological criterion of Prof. І. Parsadanov as separate independent ecological safety factor and as reference points of psychophysical scale of the partial desirability function when using it as the ecological safety factor of power plants with reciprocating internal combustion engines exploitation process was proposed. Also in the study calculated assessment of reference values of ecological indicators of reciprocating internal combustion engines as components of complex fuel-ecological criterion depending on magnitudes of effective power and coordinates of field of engine operating regimes for different levels of statutory ecological standards in force in Ukraine and previously in force was carried out. Thus, calculated assessment of reference values of complex fuel-ecological criterion and its components was performed and obtained the distribution of such reference values in field of 2Ch10.5/12 autotractor diesel engine operating regimes depending as well as dependences of such reference values on magnitudes of level of ecological standards EURO, engine effective performance and lower calorific value of engine fuel. So, the study for the first time proposes the approach to calculated assessment of reference values of the complex fuel-ecological criterion of Prof. І. Parsadanov as reference points of the psychophysical scale of the Harrington's partial desirability function when using it as the separate independent ecological safety factor of exploitation process of power plants with reciprocating ICE. The method, based on the proposed approach for calculative evaluation of reference values of the complex fuel-ecological criterion of Prof. I. Parsadanov as reference points of psychophysical scale of partial desirability function is suitable for obtaining necessary data for the complex criterion evaluation of the ecological safety level of operation process of power units with piston ICE using generalized Harrington desirability function, in the structure of which the complex fuel-ecological criterion acts as a distinct factor of environmental safety.
