Evaluating the Performance of Four Stroke Cu Engine Using Bio-Diesel Blends as Fuel

Abstract

In recent days, fuels are very limited and also depleting from day to day as utilization is very rapidly increasing. Because of these fossil fuels, the globe today is encountering with a serious environmental damage in the form of pollution. To reduce this it is now necessary to search an alternative fuel to Diesel which is prepared from renewable sources. The fuels produced in this way are termed as alternative fuels. In the current work, experimental research was carried out over naturally aspirated, water cooled and single cylinder 4-stroke and direct injection CI engine with Diesel and pungamiah biodiesel blends as fuel. From this Brake Thermal Efficiency (BTE), Brake specific fuel consumption (BSFC) and Exhaust Emissions were investigated. From the experimental results it is observed that obtained Brake Thermal Efficiency is better for bio-diesel blend B20 with minimum Brake Specific Fuel Consumption. It is also observed that there is a reduction in the quantity of Carbon Monoxide and Hydro Carbon and increased exhaust gas temperature when compared with Diesel as fuel.
