AN OPTIMISATION OF SPRAY AND PERFORMANCE EMISSION CHARACTERISTIC OF BIODIESEL AND ITS BLENDS BY VARYING INJECTION TIMING IN DIESEL ENGINE

The main objective is to optimize the various parameters of spray for different blends of biodiesel and Injection pressure mainly with respect to Spray tip penetration Spray cone angle and Sauter Mean Diameter (SMD), using the conception of Taguchi with too categorize its involvement by Analysis of Variance normally recognized like ANOVA with the help of “Minitab 14.0” software where the optimum levels of the parameters were found using higher Signal - Noise ratio. By variying the injection timing (Normal, restarted and advanced) in the Direct injection diesel engine the performance, emission and combustion characteristics was studied. It was found KB20 at 220 bar and 19o BTDC gave better performance and lower pollutant emission.
