Performance of single-cylinder compression ignition engine with indigenous castor oil bio diesel
Journal Title: International Journal of Automotive Engineering and Technologies - Year 2014, Vol 3, Issue 2
Abstract
Neat castor oil poses problems when used in CI engine. Problems are reduced to minimum by subjecting the castor oil to transesterification. Castor oil was converted to bio diesel and blended by 5%, 10%, 15% and 20% in quantity (by volume) with high-speed mineral diesel (HSD) fuel. This fuel was used on a single-cylinder compression-ignition, four-stroke diesel engine. The blended fuel gave lower emissions of CO but resulted in higher values of CO2 and NOx. Results showed that engine brake power, thermal efficiency for blended bio diesel fuel were lower than pure mineral diesel, because of lower calorific value of blended fuel. The maximum value of thermal efficiency was observed at 13% substitution of castor oil methyl ester [CME] in diesel. However, higher engine exhaust temperatures were obtained with blended fuel in comparison with that of pure mineral diesel. Chi square (2) statistical test was applied. The value for 2 (CME) 0.0524 was observed. The value concluded that there is no effect of fuel type on fuel consumption within the given range. Overall castor oil bio diesel blends fared well in terms of engine performance.
