An Experimental Investigation of Engine Performance Characteristics on Single-Cylinder Four Strok Diesel Engine by using Mixed Biodiesel at Compression Ratio 17

The current work carries raw oil of coconut and jatropha to form mixed raw oil (50% jatropha oil and 50% coconut oil) to justify the mixedoil as an alternate of diesel as fuel. The oil of coconut and jatropha has mixed by a proportion of 50% each to form mixed oil and then blended with pure diesel which will show new properties of both edible oil and non-edible oil. Mixed oil has blended with several proportions with pure diesel to form JCBO 20, JCBO 30, JCBO 40, JCBO 50.Similarly, the oil of coconut and jatropha has also blended one by one with pure diesel as JBO and CBO invariable proportions, B20, B30, B40, B50. The experimentation has been conducted to take out the performance characteristics to put forward mixed oil as an alternate fuel for diesel engines and has been carried with many blends of coconut oil, jatropha oil and mixed oil at CR 17. To test on, we have BSFC, BTE and ExGT as the combustion parameters for the four blends of JBO, CBO and JCBO, results will be compared, plotted and presented in the form of graphs. The result says that B20 blends of all biodiesel have made known very close values of Brake Thermal Efficiency (BTE) at almost all the loading.
