Experimental Studies on Performance and Emission Analysis in Diesel Engine using Bio-fuel (Neem Oil)

摘要

In present scenario Bio-fuel act as the major role in today's fuel compensation. In India Neem tree is a broadly grown up termed as a divine tree due to its large revalance in many areas of study. The current research study is projected to consider aspect related to the possibility of preparation of Biodiesel from Neem oil. This research deals with Biodiesel preparation from neem oil, which is mono ester prepared using transesterification process. Biodiesel is a safe substitute fuel to replace established petroleum diesel. It has maximum lubricity is a clean burning fuel and can be a fuel component for use in existing unmodified diesel engine. Neem (Azadirachita Indica) is a tree. Various habitual uses of pure neem oil in agriculture, medicine, etc. Neem oil has natural fungicidal, pesticidal, and medicinal properties. Neem a nature's gift it categorized in to non edible oil and mainly used in medicine and cosmetic product. Biodiesel has been gaining increased concentration from Internal Combustion Engine researcher in observation of the energy crisis and increasing environmental problems. Neem oil is being considered for biodiesel and more research is being done in this area and also lot of research going on. Biodiesel designed for complete compatibility with petroleum diesel and can be blended in any ratio from additive levels to 100% Biodiesel. The fuel properties of biodiesel including kinematic viscosity and acid value were checked. The engine power and pollutant emissions characteristics under different biodiesel percentages were also studied. Experiments demonstrated in the single cylinder diesel engine that the biodiesel produced using neem oil could reduce smoke and Carbon monoxide emissions, extensively while the NO_x emission changed a little. Thus, the ester of this oil can be used as eco-friendly substitute fuel for (CI) diesel engine.
