Abstract
The methyl and ethyl esters of vegetable oils, known as biodiesel are becoming increasingly popular because of their low environmental impact and potential as a green alternative fuel for diesel engine. In the present work, methyl and ethyl esters of nerium oil were prepared by transesterification using both methanol and ethanol. However, viscosity of ethyl esters of nerium oil (EEON) was slightly higher than that of methyl esters of nerium oil (MEON). A single cylinder stationary kirloskar engine is used to compare the Performance and Emission and Combustion characteristics between pure diesel and nerium blends. The nerium oil blends are in percentage of 20%, 40%, 60%, 80%, and 100% of nerium oil to 80%, 60%, 40%, 20% and 0% of diesel. Results show that methyl esters of nerium oil (MEON) produced slightly higher efficiency than ethyl esters of nerium oil (EEON). Exhaust emissions and Combustion characteristics of methyl esters of nerium oil (MEON) were also higher than ethyl esters of nerium oil (EEON). Hence methyl and ethyl esters of nerium blend can be used in existing diesel engines without compromising the engine performance.
Highlights
Rapid depletion of conventional energy sources, impurities are cleaned up by washing with 350 ml of along with increasing demand for energy is a matter of water for 1000 ml of coarse biodiesel
The glycerin settles at the bottom and of the Nerium oil, trans-esterification method is adopted the ethyl ester floats at the top
The UBHC emission is less in case of methyl esters of nerium oil (MEON) blends when compared to esters of nerium oil (EEON) blends, which indicates more complete combustion of the fuel
Summary
Rapid depletion of conventional energy sources, impurities are cleaned up by washing with 350 ml of along with increasing demand for energy is a matter of water for 1000 ml of coarse biodiesel. To solve both the energy concern and biodiesel is the methyl ester of nerium oil. Biodiesel is renewable and environmental method is as follows: 1000 ml of nerium oil is taken in a friendly alternative diesel fuel for diesel engine.
