Development of a Surge Tank Set-up and Its Utilisation in the Diesel Engine for NOX Emission Reduction

Modern vehicles are the major source of air pollution and diesel engines are the at most pollutant with emission of NOx ranging from 500 to 1000 ppm. NOx is the most harmful pollutant amongst various other emission such as HC, CO2, CO, PM and soot. In this research work, an experimental investigation has been performed on a single cylinder direct injection compression engine with power capacity 3.5 KW. A surge tank set-up has been developed through which cooled EGR will be utilised for reducing the NO. The results of the engine performance and emission have been investigated at different loading conditions with EGR ranging from 10% to 20%. From the experimental analysis, it has been found out that with 20%, EGR the NO emission level has been reduced by 72% that is from 290 ppm to 83 ppm on full loading conditions.
