Influence of decanol as fuel additive on the diverse characteristics of the diesel engine powered with mango seed biodiesel blend

India being a predominantly farming country requires major attention for the fulfilment of energy demands for agriculture applications. Biodiesel is a clean burning renewable fuel. In this proposed work, mango seed biodiesel is extracted from the waste mango seeds through transesterification process. The thermophysical properties are evaluated as per ASTM standards. Base tests are conducted with diesel and different blends of mango seed biodiesel. From the base test results, it is found that MSME20 shows better performance parameters. In order to improve the engine performance further, decanol is added to MSME20 at three concentrations such as 5%, 10% and 15% on volume basis. The results revealed that 5% addition of decanol to the MSME20 shows a significant enhancement in brake thermal efficiency by 3.19% and considerable reductions in the exhaust emissions such as HC, CO and smoke. However, slight increment in NOX emissions is observed at full load.
