Performance Analysis of 4-S, 2-CC. I Engine with roselle Oil Methyl Esters with Added Ignition Improver

In the present work, performance analysis of twin cylinder CI engine is performed. Roselle seed oil methyl esters are extracted from the crude roselle oil by the method of trans-esterification. The tests are conducted in the 4- stroke twin (2) cylinder CI engine and tests were conducted in different stages. Primarily, the tests were performed with4-stroke twin cylinder diesel engine with a diesel fuel and noted down the observations. In the next step, experiments are done on the same engine with different blends of Roselle seed oil like B5, B15, B25 and B35, observations are noted, performance parameters are calculated and emission noted down by using gas analyser. The results obtained in the second stage are compared to decide which the better blend with diesel fuel parameters is. After Comparison was made between the diesel and bio diesel, optimum blend is selected. In the next stage, in order to increase the efficiency of the engine ignition, improver is added to the best blend. The tests are conducted on the same engine and same operating conditions, observations are noted and performance parameters calculated and emissions are noted. In the final stage, the obtained parameters with addition of ignition improver are compared with optimum fuel blend
