Abstract

In this paper raw oil (jatropha, soybean and waste cooking fuel) is taken as potential alternative fuel for C.I. engines. The best distinction between these 3 kinds of oils and diesel fuel is viciousness. Every vegetable oil is blended with diesel in variable proportion (20% - 50%). Two sets of experiments are conducted for every fuel blend. First experiment is focussed on a performance check for pure diesel fuel. Second experiment is focussed on a performance check using many blends for each of Jatropha-diesel, soybean-diesel and waste cooking oil-diesel at fixed compression ratio of 18. The results of performance characteristics such as brake specific fuel consumption and brake thermal efficiency for every vegetable oil-diesel blends are compared with that using diesel fuel alone.
