Abstract
The need for an alternative fuel has been growing swiftly owing to the extravagant use of fossil fuels as a sole energy source for all purposes. This paper investigates the performance, emission and noise characteristics of cellulosic biofuel. A series of tests were conducted in a single cylinder, four stroke DI engine to determine the performance measuring factors such as brake thermal efficiency (BTE), brake power (BP), brake specific fuel consumption (BSFC) and emission factors such as CO emission, NO emission, CO2 emission and smoke and then, the HC emission rates were also measured. All tests were carried out at different load conditions of 25%, 50%, 75% and 100% with the constant speed of 1500 rpm. The fuel blends taken for the tests were diesel, E5, E10, E15 and E20. The E20 comparatively showed lower performance than all other fuel blends. However, when considering CO and smoke emission, the E20 fuel blends produced better reduced emission. The lower-level ethanol diesel blend showed better BT as well as BTE and BSFC. From the above findings, it is clear and evident that cellulosic biodiesel blends can be an optimal solution to meet the ongoing energy demands.
