Abstract

Vegetable oil presents a very promising alternative to diesel oil since it is renewable and has similar properties to the diesel. In view of this, crude jatropha oil is selected and its viscosity is reduced by blending it with diesel. Since jatropha oil has properties which are similar to mineral diesel, it can be used in compression ignition engines without any engine modification. This paper presents the results of investigation carried out on a four-cylinder, four strokes and indirect-injection diesel engine. The engine, operated using composition blends of crude jatropha oil and diesel, were compared with mineral diesel. An experimental investigation has been carried out to analyze the performance characteristics of a compression ignition engine from the blended fuel (5%, 10%, 20% and 30%). A naturally aspirated four-stroke indirect injection diesel engine was tested at foil load conditions, speeds between 1000 and 3500 rpm with intervals of 500 rpm. Results obtained from the measures of torque, power, specific fuel consumptions, thermal efficiency and brake mean effective pressure are nearly the same between blended and diesel fuel. An overall graph shows that the performance of relevant parameters from blended fuel is most likely similar to the performance produced from diesel. The experimental results proved that the use of crude jatropha oil in compression ignition engines is a viable alternative to diesel.
