Emission and Performance Characteristics of Diesel Engine Using Mamey Sapote Biodiesel as Alternate Fuel
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 7
Abstract
In the present study an experimental investigation was carried out with Mamey Sapote oil as an alternative fuel in a compression ignition engine. The problems associated with fruit seed oil are high viscosity, low volatility and high reactivity, but at the same time their higher cetane number, lower sulphur content and higher oxygen concentration are the desirable properties to use as a fuel in compression ignition engines. The process of transesterification of fruit seed oil with methyl alcohol provides a significant reduction in viscosity, thereby enhancing the physical properties of fruit oil. The current paper reports a study carried out to investigate the combustion, performance and emission characteristics of Mamey Sapote oil methyl ester with diesel fuel on a single-cylinder, four-stroke, direct injection and water cooled diesel engine. This study gives the comparative measures of brake specific fuel consumption, brake power, brake thermal efficiency, mechanical efficiency, volumetric efficiency, CO, CO2, HC, NOx and smoke opacity. Mamey Sapote Biodiesel was blended at 5%, 10% , 15% and 20% ratio with diesel fuel in the present study. The results indicate that the CO and HC emissions were lower than diesel at 15% of MSO, and NOx emissions decreased up to 20.5% for 15% MSO when compared with diesel. From the investigation it can be concluded that biodiesel can be used as an alternative to diesel in a compression ignition engine without any engine modifications.
