Analysis of copper nanomaterial as catalyst for reduction of NOx gases in diesel engine

Abstract

In the automobile sector, the removal of pollutants (NOx) generated by diesel engines remains a fascinating scientific and technological issue. The emissions of the vehicle are in compliance with BS III standards. The Indian government came up with the Bharat Stage Emission Standards in order to place limitations on the amount of air pollution that can be released into the atmosphere by machinery that uses an internal combustion engine, such as automobiles. The central pollution control board, which is an agency under the ministry of environment and forests, is in charge of defining the requirements and the timetable for their implementation. The brake-specific fuel consumption decreased by 4.5% and 8%, while brake thermal efficiency rose by 5.5% and 14.6%. However, with CO additions of 1000 and 2000 ppm, respectively, nanoparticles increased the chemical processes and decreased the ignition delay time by 3.03% and 5.45%. The amounts of CO, HC, and NOx emissions decreased by 14.6%, 20.8%, 6.2%, and 13.4%, respectively. The catalytic oxidation of carbon monoxide is an important reaction in both commercial and academic settings. For the past years, hoplite, which is composed of copper-manganese oxides, has served as a low-cost and widely available carbon monoxide abatement catalyst.
