DETERMINATION OF REFERENCE VALUES OF COMPLEX FUEL AND ECOLOGICAL CRITERION AS THE SEPARATE INDEPENDENT FACTOR OF ECOLOGICAL SAFETY

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.
