    COMPARATIVE STUDY OF USING DIESEL AND BIO-DIESEL IN A SINGLE CYLINDER DIESEL ENGINE
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2022) DONADKAR RUJUTA RAJENDRA; SHASHIDHAR H. BADAMI
    In fact the concept of using biodiesel was known since 18th century but now in recent years it is gaining more popularity due to the facts that the depletion of fossil fuels, environmental effect, global warming, the stringent emission standards and international crises of fossil fuels have forced the world to find an alternative fuels. Biodiesel is one of the most important alternative fuel to fossil fuels mainly because it is renewable, nontoxic and environmental friendly and it seems to be a solution for the fossil fuel. The biodiesel can be used in an internal combustion engine with little or no modification to the engine. So based on the importance of use of biodiesel in an internal combustion engine, a comparative study of using diesel and biodiesel tests were conducted as per the Bureau of Indian standard . The tests were conducted by varying the load from no load to full load for standard diesel and for four biodiesels such as Indizel, Dairy Scum Biodiesel [DSB], Waste Vegetable Oil [WVO], and Pongamia Pinnata (Honge) in different blended ratios like B25, B50, B75, B100. Among all Biodiesels, Dairy Scum Biodiesel has received more attention. A maximum BP of 4.504 kW was observed than neat diesel, BSFC of Indizel B75 was higher than diesel i.e., 0.681 kg/kW/hr, Brake Thermal Efficiency of DSB was 30.05 % as compared with other Biodiesels. The least and highest unaccounted heat loss among four biodiesels were DSB B75 [346.49 kJ/kg] and DSB B50 [763.8 kJ/kg] respectively as compared with that of standard diesel [445.37 kJ/kg]. Mann Whitney (U test) was done for all the biodiesels independently. However, DSB, Indizel (B75)and DSB (B75) have shown good value in terms of BP, BSFC and unaccounted heat loss respectively as compared to standard diesel, which is the significant contribution of biodiesels in terms of their performance parameters are concern.
