Abstract : In the present paper the work is done based on the experimentation of biodiesel blends using diesel and waste cooking oil with and without adding cow urine as additive in various proportions. The properties such as the flash point, fire point, kinematic viscosity and the calorific values of the blends with and without additive are determined. Then all the biodiesel blends are used as fuel separately in the diesel engine. The emission characteristics and the performance parameters are evaluated. From the results, it was observed that the blends with additive as shown slight improvement in performance but significant reduction in emission. Fuel consumption was more for the higher percentage blends with respect to increasing brake power. Brake thermal efficiency was higher in 50% for the both the blends with and without additive. It can be concluded stating that the same procedure can be followed with various blend ratios in order to differentiate and find the optimum blend as an alternative fuel. © Published under licence by IOP Publishing Ltd.
