Determination of fuel-ecological efficiency of exploitation process of diesel ICE of power plants with considering of emission of benzo(a)pyrene and polycyclic aromatic hydrocarbons in exhaust gas flow

Abstract

In this study have been improved the previously proposed by the author methodicas of determination of magnitudes of mass hourly emissions of benzene(a)pyrene and polycyclic aromatic hydrocarbons in diesel engine exhaust gases flow. It were obtained distributions of magnitudes of such emissions on operational regimes field of 2Ch10.5/12 autotractor diesel engine and on regimes of standardized steady testing cycle ESC. It have been improved the mathematical apparatus and methodica of application of complex fuel-ecological criterion of Prof. Igor Parsadanov. It were obtained distributions of magnitudes of such indicator of ecological safety level of power plants with reciprocating ICE exploitation process on operational regimes field of 2Ch10.5/12 autotractor diesel engine and on regimes of standardized steady testing cycle ESC and also obtained its middle exploitation magnitude. It is established that, It is detected that middle exploitation magnitudes of values of criterion Kfe and effect δKfe for all studied variants of considering of mass hourly emissions of B(a)P and PAH in diesel engine exhaust gases flow almost equal to each other and declines the value of Kfe criterion on 29 – 32 % – from 63 ‰ up to 42 – 45 ‰.
