EXPERIMENTAL INVESTIGATION AND EMISSION REDUCTION TEST OF BIO DIESEL BY USING SCR FOR DI DIESEL ENGINE
Subject area: Science,Engineering and Technology · Area of research: MECHANICAL ENGINEERING
Abstract
Diesel engines are widely used in many areas like automobiles, locomotive marine engines power generations etc., due to its high power output and thermal efficiency. Even though the diesel engines give more benefits, the human discomforts caused by the pollutant emission of these engines have to be considered. The major pollutant emissions of the diesel engines are particulate matters, smoke and the oxides of nitrogen (NOx). Out of these pollutant emissions, the oxides of nitrogen are considered as the most harmful pollutants to the human health. Emissions of nitrogen oxides (NOx) contribute seriously to air pollution, which is a major environmental problem of NOx react with moisture in the air to form nitric acid, contributing to soil and water acidification in sensitive areas. In the after treatment method, urea solution is sprayed in the exhaust stream which is at a temperature of 3000C to 450oC. At this high temperature of exhaust gas, the urea starts to decompose and form ammonia. The ammonia acts as reduction against and converts the oxides of nitrogen (NO and NO2) into free nitrogen (N2) and water vapour (H2O). There are many techniques being tried to control NOx emission from diesel engine. In this project, the emissions controlled by after treatment of exhaust gases. The selective catalytic reduction (SCR) of NOx is a promising technology for NOx reduction.
