Production of Bio-Diesel to Neem oil and its performance and emission Analysis in two stroke Diesel Engine.

摘要

In India Neem tree is a widely grown up termed as a divine tree due to its wide relevance in many areas of study. This paper deals with Biodiesel production from neem oil, which is monoester produced using transesterification process. Biodiesel is a safe alternative fuel to replace traditional petroleum diesel. It has high lubricity, clean burning fuel and can be a fuel component for use in existing unmodified diesel engine. Neem (Azadirachita Indica) is an evergreen tree, which is endemic to the Indian Sub-continent and has been introduced to many other areas intropics. The fuel properties of biodiesel including flash point-and fire point were examined. The engine properties and pollutant emissions characteristics under different biodiesel percentages were also studied. The results shows that the biodiesel produced using neem oil could reduce Carbon monoxide and smoke emissions significantly while the Nitrogen oxide emission changed slightly. Thus, the ester of this oil can be used as environment friendly alternative fuel for diesel engine.
