Catalytic reduction techniques for post-combustion diesel engine exhaust emissions
MetadataShow full item record
Strict exhaust emission regulations set for limiting the air Pollution caused by motor vehicles have oriented the producers and researchers to investigate new techniques to reduce exhaust emissions. The main pollutants caused by diesel engines are particle matters (PM), nitrogen oxides (NO,), hydrocarbons (HC), and carbon monoxides (CO). Among the preventive actions to keep the emissions caused by motor vehicles at a certain level are enhancing the fuel quality, preventing the pollutant formation in the engine, and developing the post-combustion emission control systems. There are many different technologies used for reducing the amount of pollutants in diesel engine exhausts. In this study, the main post-combustion techniques applied for reducing these pollutants catalytically are being examined.
