Experimental study of Exhaust Emissions from Diesel Engines using Gas Analyser and Smoke Meter with Activated Carbon Filter

Abstract

Abstract The adsorption technique has proven a better solution to reduce emission in diesel engines. Activated carbon is taken as an adsorbent for the study to investigate the engine behaviour on its performance and emissions. The experimental setup along with testing of the emission for gas analysers as well as for smoke meters was performed. In this paper, the emissions from diesel engines are reviewed. To reduce the emissions from an automobile, experimental methods of adsorption using activated charcoal in diesel engines is set up. Activated carbon is one of the best adsorption materials due to its high porosity and capture capacity, when reacted with other reagents in order of activation. The measurement of emissions from the diesel engine is obtained using gas analyser and smoke meter, both before and after the installation of filter. After successive results obtained by using these devices, the performances of the devices and efficiencies of the filter used is compared. In this experiment, we can see that the filter (activated carbon) has efficiently reduces the value of HSU by 43.73% and K value by 48.94%. Hence, the overall efficiency of activated carbon used is about 46%.
