Abstract:

The present work investigates the performance of a diesel engine the use of Juliflora Oil biodiesel in phrases of brake specific fuel consumption and brake thermal efficiency as well as exhausts emissions. Juliflora Oil, a non-edible instantly vegetable oil became mixed with petroleum diesel in various proportions to evaluate the overall performance & emission characteristics of a single cylinder direct injection constant speed diesel engine. Blends of diesel oil and Juliflora Oil biodiesel with concentrations of 10 %( B10), 20 %( B20), and 30 %( B30) were used as fuels. Tests have been achieved for engine operations and engine overall performance parameters such as fuel consumption, brake thermal efficiency, and exhaust emissions (CO, HC and NOx) have been recorded. Among the blends B20 has proven a higher overall performance with respect to brake specific fuel consumption and brake thermal efficiency. All blends have proven better CO emission after about 75% load. The emissions of HC are relatively decrease at B20. However the NOx emissions have been better for all of the blends at all loads. The results screen that B20 has an overall higher performance as regards to each engine performance and emission characteristics.
