摘要

在这项研究中,作者改进了其先前提出的方法,用于确定柴油发动机废气流中苯(a)芘和多环芳烃的质量小时排放量的值。研究的目的是在考虑苯并(a)芘和多环芳烃作为有毒和致癌污染物排放的情况下,获得表征柴油机开采过程生态安全水平的复杂燃料生态判据值。在2Ch10.5/12型自动拖拉机柴油机工况场和标准化稳态测试循环ESC模式下,得到了该排放的分布。对Parsadanov教授提出的复杂燃料生态判据的数学装置和应用方法进行了改进。得到了往复式内燃机开发过程电厂生态安全水平各指标值在2Ch10.5/12型汽车拖拉机柴油机运行模式和标准化稳态试验循环ESC运行模式上的分布及其平均运行值。结果表明,考虑柴油机废气中B(a)P和多环芳烃质量小时排放的所有研究变量的Kfe标准的平均工作值和δKfe效应几乎相同,并使Kfe标准的值从29 - 32% - 63‰降至42 - 45‰。所获得结果的科学新颖性在于,Igor Parsadanov教授考虑到以RICE EG为有毒污染物的大量小时排放的苯并(a)芘和多环芳烃,采用基于标准的方法评估作为发电厂一部分的汽车拖拉机柴油发动机的燃料生态效率的方法,以及确定这些污染物的排放量和可重性的方法得到了进一步的发展该数学装置在标准化稳态测试循环中的应用方向。

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
In 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 Parsadanov 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.
