Determining the amount of harmful emissions of diesel internal combustion engines

Abstract

The authors insist on creating a methodological apparatus to ensure an objective assessment of the negative impact of mobile sources on the environment, in particular, an adequate determination of the qualitative and quantitative parameters of emissions from internal combustion engines of locomotives. It is not yet known in what direction the absolute values of the «ecological deductions» of the corresponding enterprises of the locomotive facilities of the Ukrainian railways, or industrial railway transport enterprises operating the locomotives will change in practice. The talk is exclusively about the objectivity of the quantitative assessment, without possible proposals of an active influence on the technical condition of the power plants of diesel locomotives. The authors proposed to improve the technique of quantitative operational assessment of diesel ―sources‖ of harmful emissions, regardless of the type of transport work they perform, by implementing the possibility of installing control and diagnostic fuel-ecological complexes (CDFEC) at the time installed in locomotive depots, to carry out an environmental assessment of the diesel locomotive fleet their maintenance (registration), pay attention to the bench fuel-measuring complexes, which must necessarily be composed with control and measuring facilities of depot stands, conduct comparative studies on the conformity of bench test and measurement complexes to the production conditions of operation and propose an indicator to take into account such differences, start a monitoring program and develop new approaches to reduce the impact of railway mobile sources of pollution on the environment; analysis of the current European standards for rationing and monitoring emissions from diesel locomotives and to perform analysis of ecologic - economic risks for in the future implementation of these EU environmental directives and standards.
