Reduction of Exhaust Emissions on a Biodiesel fuelled Diesel Engine with the Effect of Oxygenated Additives

摘要

This paper investigate the use of neat biodiesel on a large scale is raising certain constraints, both in terms of long-term availability of feed stock, and high NOx emissions. However, HC and NOx emissions of neat biodiesel are still on the higher side. The main aims of the present work is to carry out an experimental evaluation of single cylinder diesel engine by adding 10% di-ethyl ether (DEE) with Karanja methyl ester (KME) in order to further improve performance and emission characteristics of biodiesel. The results showed that the brake thermal efficiency slightly increased and the exhaust emissions are significantly decreased with DEE with biodiesel at full load conditions.
