Abstract
The present research work primarily focuses on the extraction of mango seed biodiesel from the waste mango seeds through transesterification process. Preliminary tests were conducted with diesel and different blends of mango seed biodiesel such as MSME10, MSME20, MSME30 and MSME40 at standard operation conditions of Kirloskar diesel engine. It was found MSME20 have shown better performance parameters. Further, diethyl ether was added to MSME20 at three levels like 5%, 10% and 15% on volume basis. Test results revealed that 5% addition of DEE to MSME20 has shown 3.96% enhancement in brake thermal efficiency at full load. Further, it was found for MSME20 DEE 5%, the exhaust emissions such as CO, HC and smoke were decreased significantly by 11.2%, 10.41% and 9.58%, respectively, when compared to the MSME20 at full load. Hence, the use of MSME20 DEE 5% biodiesel blend could encourage achieving the promising results from the diesel engines.
