Preparation of biodiesel and experimental investigation of biodiesel blends on diesel engine at varying speed.

Abstract

Because the world's fossil fuel reserves are depleting at an alarming rate as a result of increased consumption, biodiesel is a useful alternative to fossil fuels in many scenarios. Since biodiesel emits fewer harmful emissions, it's an environmentally friendly fuel. Biodiesel can be produced at a lower cost and can be used without any modifications in the engine. The most acceptable process for biodiesel production is base-catalysed transesterification. In this present research work we prepared and compared the characteristics of the biodiesel with conventional diesel fuel. Waste fry oil taken form potato chip industry and Jatropha from Jatropha seeds methyl ester-based biodiesel was prepared using transesterification process. The pure bio-diesel was blended with diesel in some proportions making it as B20, B30, B40, B50 blends and tested in a four-stroke, four-cylinder, diesel ignition engine running at five different engine speeds 1600, 1800, 2000, 2200, 2400 respectively.
