The carbon emissions from the diesel engines is not so high but after the reduction of NOX emissions the pollutants present in the exhaust gas is carbon and particulate matter. The stringent emission norms lead to maximum possibility of reduction of pollutants in exhaust gas so activated charcoal or activated carbon is used to adsorb the carbon emissions from the engine. Activated charcoal is grained into fine pieces they should be the size that they could not pass through the metal mesh fixed at the both the ends of the carbon container. The activated charcoal particulates should be heavy that they should not be carried away by the exhaust flow. The particulate matter or HC emissions are reduced at the catalytic converter so the exhaust emissions are mostly reduced and exhaust gasses are free from pollutants. The engine is operated for different load conditions like 100%, 75%, 50%, 25%, and 0% and the different emissions like CO, HC, CO2 and NOx. The activated carbon is linked with the catalytic converter to further reduce the emissions from the engine. The surface area of the activated carbon also plays a major role in reducing carbon emissions by allowing better adsorption of carbon.
