This paper present engine performance study of blended diesel ethanol derived from Cadaba farinosa forskk plant. The blends were formulated as: BDE2 (97% Diesel and 2% bioethanol volumetric proportion), BDE4 (95% Diesel and 4% bioethanol volumetric proportion), BDE6 (93% Diesel and 6% bioethanol volumetric proportion), DE8 (91% Diesel and 8% bioethanol volumetric proportion) and BDE10 (89% Diesel and 10% bioethanol volumetric proportion) and 1% biodiesel (palm oil methyl esters) was maintained for all the blended test fuel samples to avoid phase separation. on a TD110-115 single cylinder, four stroke and air-cooled, compression ignition engine test rig, under different loading conditions in line with the SAE practice SAE J1312 June 1995 test protocol. The results showsthat, a decrease in torque and brake power is due to higher cetane number of biodiesel, the higher calorific value of diesel and that of BDE2 to BDE4 fuel mixtures, as well as complete combustion of fuels. The specific fuel consumption was found to be lower in all blended fuel samples than diesel, and specific fuel consumption decreased up to 83.3% load and increases for all samples. BSFC of all blends were lower than that of diesel and increases with increase in percentage blend.The air -fuel ratio reduces, as the concentration of bioethanol in the blended sample of diesel and bioethanol and engine load increases. However, it shows average difference of 6.18% and 9.4% from the AFR of diesel fuel, BDE2, BDE4 and BDE6 bioethanol-Diesel fuel are 1.78%, 2.24% and 2.81% lower than diesel fuel samples respectively. For all the fuels, the brake thermal efficiency increases with increase in load. This can be attributed to the increase in power with increase in load. For reasons of its satisfactory engine performance behavior, fuel conservation advantages, the candidacy of Cadaba farinosa forssk ethanol and diesel blends, present the prospects of a potential fuel source and diesel fuel extender for compression ignition engines.
