Investigating the role of catalytic converters in vehicle exhaust to reduce air pollution

Abstract

Air pollution is considered one of the major environmental problems that arises from the combustion of fossil fuels. Vehicles are recognized as a significant source of harmful gases such as Carbon monoxide (CO), unburned Hydrocarbons (HC), and Nitrogen Oxides (NOX), which pose a serious threat to human health and the environment. This article examines the role of catalytic converters in reducing air pollution. The research method of this article is based on a developmental objective and is analytical-descriptive in nature. Additionally, data collection was conducted through library research by reviewing related studies. Catalytic converters are valuable devices installed in vehicle exhaust systems that reduce air pollution by converting harmful gases into non-harmful gases. Research results show that catalytic converters can convert 90 to 97 percent of harmful gases into non-harmful gases. Additionally, there is a need for further research to improve the performance of these converters. Especially in Afghanistan, which faces serious air pollution problems, the use of catalytic converters can lead to a reduction in diseases and the preservation of public health. Ultimately, paying attention to the maintenance and proper use of catalytic converters in vehicles, especially in urban areas, is of special importance and can help improve air quality and public health.
