Possibility of reducing the technogenic load on the environment by reducing oil waste in diesel

Abstract

The study is aimed at solving an important environmental problem of reducing the technogenic load on the environment created by automotive diesel engines. The issue of reducing the toxicity of exhaust gases by reducing the waste of oil in the combustion chamber of the cylinder-piston group for various modifications of 15/18 diesel engines is considered according to the results of bench tests. It was found that a decrease in oil burnout in a diesel engine is accompanied by a decrease in CO, CH, PM emissions with exhaust gases. At the same time, a slight increase in emissions of nitrogen oxides NOx was observed. It was found that with a change in oil burnout from 0.32 to 0.6% of fuel consumption, the estimated indicator for nitrogen oxides decreased by 10%, for carbon monoxide - increased by 52%, for hydrocarbons - increased by 50%, for solid particles - increased by 94%. The results of the study showed that the technogenic load matters. The indicator of technogenic load was HTL = 43.63 tl/g with oil burnout of 0.32% and HTL = 39.87 tl/g with oil burnout of 0.6% due to reduction of NOx emissions.
