Combustion and emission characteristics of diesel fuel blended with raw jatropha, soybean and waste cooking oils

Abstract

In the present investigation raw oil (jatropha, soybean, and waste cooking fuel) has analyzed to prove its suitability as an alternative fuel in compression ignition (CI) engines. The blends of high vegetable oils with diesel are created and analyzed experimentally. The raw oil is blended with diesel in varying proportion (from 20 % to 50 %) using raw vegetable oil (100 %). Two sets of experiments are conducted for each fuels blends, one for performance analysis & other for emission test. The analysis has been performed for pure diesel and diverse blends of Jatropha-diesel, Soybean-diesel and waste cooking oil-diesel at compression ratio (CR) of (16.5). The performance and emission characteristic for each raw oil-diesel blends are investigated and the comparison results are presented. The result reveals that B20 blends of all biodiesel have shown very close values of Brake Thermal Efficiency (BTE) at all loading.
