Study of the emissions in the diesel engines: A review

Abstract

Diesel engines are one of the main sources to supply the rapid growth of energy consumption worldwide. They have been widely used in the public and commercial transport sector due to their greater durability and efficiency. The current study in Diesel engines is focused on emissions from exhaust gases, as they are causing problems in human health and the ecosystem, because they contain dangerous substances, such as organic carbon, trace elements, elemental carbon and inorganic ions. In this paper, we study the different investigations on pollutant emissions in engines, focused on the mechanisms of formation of pollutants, the techniques to reduce these emissions and how they affect human health. With this, it will be possible to project the necessary improvements in this type of systems, to reduce the impact of these thermal machines on the environment.
