Performance of a DI Diesel Engine by Using Bio Diesel (Palm Oil)

Now a day’s Increase in energy demand, stringent emission norms and depletion of oil resources led to find alternate fuels for internal combustion engines. Many alternate fuels like Liquid Petroleum Gas (LPG), alcohols, biodiesel, Compressed Natural Gas (CNG), etc have been already commercialized in the transport sector. In this context, palm oil renewed interest. This palm oil can be converted in biodiesel using a process called trans-estrification. This biodiesel are blended with the diesel and used as an alternate fuel for the CI engines. In the present work the performance of characteristics and emissions are evaluated on single cylinder 4 stroke diesel engine fuelling with 20%, 30%, 50%, for biodiesel. Due to high viscosity of the biodiesel 60% and more percentages have been not taken into Palm oil-diesel blend. Experiments was carried out of a diesel engine by using palm oil as alternative fuel which is single cylinder, four-stroke, water cooled at constant speed engine capable of the developing a power output of 7.5kW at 1500 rpm. Performance parameters such as the brake power, specific fuel consumption and the indicated thermal efficiency are calculated based on experimental analysis of the engine.
