Abstract: Biodiesel from bio-oils are considered as the promising renewable alternative fuel for CI engine. However the damped waste cooking oil poured in the earth is one of the contributors of water and environmental pollution. In this study, biodiesel from waste cooking oil (WCO) is produced by transesterification reaction and blended with diesel fuel (B10, B20, B30, B40, B50). These blends were tested in single cylinder, 4-stroke, water cooled CI engine at different loads with 1500rpm constant engine speed to evaluate the performance and emission characteristics. Performance study contains brake thermal efficiency, specific fuel consumption while emission study consider NOx, CO, CO2 emission. During experimentation it was found that an increase of load leads to increase of brake thermal efficiency and decrease in specific fuel consumption. It was also observed that the results using biodiesel have similar characteristics to that of diesel. The NOx emission increases as load increases, while CO emission decreases for B10, B20 as blending increases.CO follows the trend similar to that of diesel. Also CO2 emission increases at partial and medium loading condition.
