Performance and emission evaluation of a diesel engine fueled with methyl ester of neem oil and filtered neem oil

Abstract

<smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="City"><smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="place"> Neem oil methyl ester (NOME) was tested in 4-stroke single cylinder water cooled diesel engine. Brake thermal efficiency of NO100 has been found 63.11% higher than that of diesel at part load whereas it reduces 11.2% with diesel fuel at full load. As NOME is concerned, HC is reduced at all load condition, whereas smoke is also reduced at full load condition. NOx has reduced slightly at all load condition, and EGT showed increasing trend at full load condition. Other emissions (CO, CO₂ and O₂) do not contribute bad effect on engine. Thus, NOME can be a substitute for diesel fuel in diesel engine. </smarttagtype></smarttagtype>
