NOx Reduction of Diesel Engine with Madhuca Indica biodiesel using Selective Catalytic Reduction (SCR) in different flow rates

An Experimental Study of Production and Properties of Animal Fats Biodiesel

“…Here, Glycerol, which is a co-product in the biodiesel production, refining and unrefined. There was a considerable reduction takes place while adopting Selective Catalytic Reduction (SCR) fuelled with Madhuca India biodiesel blends [8]. The diesel engine was investigated fuelled with various blends of preheated cotton seed oil.…”

DCU development of diesel engines under V-type procedure

“…The application of SCR has been widely used in diesel engines [5]. The principle of SCR system is spraying aqueous urea solutions into the exhaust pipe of the diesel engine, reacting with nitrogen oxides and making it into harmless nitrogen and aqueous vapor [6] [7]. The conversion efficiency of nitrogen oxides has its limit which is determined by the temperature of the catalyst and space speed.…”

Study of the Emission Characteristics of the SCR System on CI Engine Fuelled with Diesel-Ethanol Blends and an Optimised Urea Injection System

“…Themajor amount(66%) of the total NO x emissions was caused by human activities involving combustion processes [9] [10]. The remaining NO x emissions were derived from natural sources, such as lightening(16%) and microbiological activities (16%) or as input from the stratosphere [11] [12].The formation of nitrogen oxides(NO x ) during the combustion of fuel in an engine was a generic problem. Nitrogenoxides (NOx) are one of the major pollutants from diesel engines.Sincethese affect the environment as wellas humanhealth, emission restrictionshavebeen introduced for nitrogen oxides as well as forparticulatematter [13][14] [15].TheEuro VI emission standards was introduced in 2013; sincethe fuel economywas improved with higherNOxemissions, differentafter-treatment strategies can beusedtodecreasetheemissions of NOxwhile maintaining agood fueleconomy [16] [17].…”
