Experimental investigation on diesel engine emission using selective catalytic reduction technique with urea injection

Abstract

Diesel engines are widely used in many fields such as automobiles newlinelocomotives marine engines power generators etc due to their high torque newlineand thermal efficiency Even though the diesel engines give more benefits newlinethe pollutant emissions of these engines cause a lot of problems to people newlineThe major pollutant emissions of the diesel engines are particulate newlinematter hydro carbon smoke and the oxides of Nitrogen NOx Out of these newlinepollutant emissions the oxides of Nitrogen are considered to be the most newlineharmful pollutant to human health plants and environment Hence NOx newlineemission from engines and vehicles are legislated and made more stringent at newlineregular intervals Therefore the industries manufacturing diesel engines are newlineunder pressure to device various methods to minimize the emission of NOx newlineAmong the many methods available to reduce NOx the after treatment is less newlineexpensive and simple newline newline
