PERFORMANCE AND EMISSION CHARACTERISTICS OF DIESEL ENGINE FULLED WITH BLENED BIODIESEL FROM NEEM AND NYGER

The contribution of Neem and Nyger as a source for biodiesel production will be of great importance in the upcoming days. In India Neem tree is a widely grown up in many areas of study. Neem is a large tree growing about 20 m in height with spreading branches forming a broad crown, starts fruiting after 4 years. It thrives well in dry, stony shallow soils and even on soils having hard calcareous or clay pan, at a shallow depth. Nyger seeds observe as sunflower seeds in shape, but is smaller in size and black. It bears a fairly thick, adherent seed coat and can be stored for up to a year without deterioration. Biodiesel production from Neem and Nyger oil, which is monoester produced using transesterification process. It has high lubricity, clean burning fuel and can be a fuel component for use in existing unmodified diesel engine. Keywords: Nyger, Transesterification, BSFC, Unburnt hydrocarbon
