PERFORMANCE AND EMISSION ANALYSIS OF DIRECT INJECTION DIESEL ENGINE FUELLED BY BIODIESEL WITH Al2O3 NANO ADDITIVES

PERFORMANCE AND EMISSION ANALYSIS OF DIRECT INJECTION DIESEL ENGINE FUELLED BY BIODIESEL WITH A1203 NANO ADDITIVES Now a day's some of counties stopped the production of diesel vehicles the countries are Japan, UK, German, India and so., Biodiesel from watermelon seed oil (WSO) had a lot of appeal and could be a different alternative to diesel without any mechanical modifications. This will help protect the environmental status of crude oil in oil imports, which is expected to increase by 82% by 2020. The watermelon biodiesel blends were tested in diesel engine without any modification blends reveals the better performance and emissions were observed. Five set of watermelon biodiesel blend samples are prepared such as B20, B40, B60, B80 and B100. Properties of watermelon blends are finding out as per standards and compared to diesel fuel. Testing is carried out to analyze the performance and emission characteristics of diesel engine fuelled with various blends of Watermelon biodiesel. The observation of testing fuels are conducted on kirloskar single cylinder water cooled constant speed direct injection diesel engine with eddy current dynamometer. The engine parameter such as injection timing 23° bTDC and injection pressure 210 bars were maintained constant throughout the experiment. From the test results, it might be observed that among different blends B20 blend showed optimum performance and emission results compared with the neat diesel.The research study, performance and emission analysis of a single cylinder diesel engine is fuelled blends of B20 and diesel. The B20 is taken as standard biodiesel blend from the previous research. The nanoparticles is added in the proportions of 20 PPM, 40 PPM and 60 PPM are mixed with the B20 [20% of Watermelon Seed Oil (WSO) and 80% of Diesel]. After the mixing of additives with a ultrasonicator for 30 minutes for each and every sample B20 with 20PPM, 40PPM and 60 PPM of additives. From the sample fuels, we get the best formed fuel from these samples A or sample B or sample C. The B20 with addition gets the better performance for compared to B20. The performance are brake thermal efficiency, total fuel consumption and specific energy consumption are taken the reading and calculation. The performance and emission analysis are carried out for B20 with additives compared to B100 and diesel. The emission analysis is Hydrocarbon (HC), Carbon monoxide (CO), Carbon dioxide (C02), Oxide of Nitrogen (NO) and smoke. From this
