摘要

This experimentation focuses on the diesel engine performance and emission characteristics using coconut biodiesel blends without any engine alterations. The fuel properties of diesel and biofuel blends are analyzed. The engine is capable of running without difficulty in biodiesel mode. Engine performance test interval is 200 rpm. And, emission tests have been carried out at maximum speed at 100%, 90% and 80% throttle position. Outcome of this experimentation showed that fall in brake power, while rise in specific fuel consumption has been identified for biodiesel over the entire speed range compared to sole fuel (diesel). In case of engine exhaust gas emissions, raising CO_2 and diminishing HC, CO, Smoke Density and increasing of NOx emissions have been identified for biodiesel compared to diesel. Thus has been carried out at full load, keeping throttle 100% wide open with variable speeds at an, it can be concluded that BD1,BD2 and BD3 can be used in diesel engines without any engine modifications and have positive special effects both in terms of exhaust emission reductions and engine performance. This article pointed out that biofuel has potential to reduce greenhouse gas emission for more than 80%; which most of the developed countries have put their target and authorization to use biofuel.
