The study of the environmental pollution produced by internal combustion engines of locomotives

Abstract

It is believed that vehicles with internal combustion engines in European countries release about 89% of CO, 52% of NOx and 44% of volatile organic compounds of the total amount of pollutants [1, 5]. At the same time, railway transport releases only about 3% of all pollutants emitted by transport facilities. Railway transport of Lithuania mainly consists of locomotives, therefore, the main pollutants are products of incomplete combustion of fuel and other fuels, i.e. particulates, carbon monoxide CO and hydrocarbons CmHn. There are also large quantities of sulphur oxide SOx compounds, i.e. combustion products of sulphur admixtures. Nitrogen oxides NOx make the main part of poisonous substances released by Diesel locomotives (about 60 %). They are formed during the combustion of the nitrogen contained in the air.
