APPLICATION OF THE SCR SYSTEM IN MODERN INTERNAL COMBUSTION ENGINES TO REDUCE EMISSIONS OF NITROGEN OXIDES

Abstract

The designs of power units in modern vehicles are continuously being improved, and the requirements for harmful emissions are becoming stricter. The modern AdBlue exhaust gas cleaning system deserves special attention, the concepts of performance, maintainability and operation, when emission standards are tightened, and exhaust gases can contain a large content of harmful substances that adversely affect the environment and public health.

At the same time, it is necessary to understand whether it makes sense to install, maintain in working condition and how well the SCR system copes with emissions, in particular NOx emissions. Using Internet sources, various literature, the authors conducted a study and analysis based on the reviews of car owners, various tests in which the advantages and disadvantages of the SCR system were compared with the Unified State Register system.
