Experimental Investigation on the Performance and Emission Characteristics of Compression Ignition Engine Fuelled with Various Blends of Water Melon Biodiesel

The water melon biodiesel blends were tested in diesel engine without any modification blends reveals the better performance and emissions were observed. Five set of water melon biodiesel blend samples are prepared such as B20, B40, B60, B80 and B100. Properties of water melon blends are find 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 Water melon 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.
