Repercussion of Neem Oil & Palm Oil Biodiesel Blends (B5 & B10) and Diethyl Ether & 1-Butanol with Palm Oil Biodiesel Blends on Performance of a Unmodified Diesel Engine

The biodiesel from inedible Neem oil (NOME; neem oil methyl ester), and edible Palm oil (POME; palm oil methyl ester) taken from economical feedstock be contemplated as less emission producing renewable fuel in current energy resource crisis situation. In this study methyl ester from neem & palm vegetable oil were produced in an experimental set-up and tested for relevant prerequisite as engine fuel (ASTMD6751 & EN14214). This study explored the repercussion of neem oil & palm oil biodiesel blends (B5 & B10) on direct injection compression ignition engine performance against petroleum diesel. Also addition of additives, Diethyl ether and 1-Butanol with palm oil biodiesel blends were empirically inspected for changes in performance. The engine was loaded and paired with a dynamometer (TMEC10, eddy current). The empirical reactions indicated that against petroleum diesel the numerous biodiesel blends display no compelling advances in engine performance in high load circumstances even with additives. But in low load conditions the engine performance outcome in term of BTE (brake thermal efficiency) indicated that NOME & POME blends (B5 & B10) could successfully be adopted in conventional diesel engine.
