Parametric Optimization of Brake Power and Specific Fuel Consumption on A Single Cylinder VCR Engine By Taguchi Method Using Jatropha Biodiesel Derived From Jatropha Curcas Oil Conducting Experiments As Per IS 10000 Approach

Abstract

The main purpose of this research work is to evaluate the predicted values for the corrected Brake power (BP) and corrected specific fuel consumption (SFC) of single cylinder VCR diesel engine operated on diesel and jatropha biodiesel blend (0%, 25%, 50%, 75%, 100%) derived from jatropha curcas oil. Current research work concentrates on the performance parameters of engine 4 stroke single cylinder CI engine, carried out using ISO 10000 approach in which the brake power and specific fuel consumption are corrected via correction factors “α‟ & “β‟ respectively. Also examine combined effect of brake power at various blends and loads in order to find out optimal performance of CI engine by conducting experiments as per IS 10000 method. The experimental work will be used to find out load and blend ratio for optimal brake power and lower specific fuel consumption by using Taguchi’s approach using Minitab software. A set of experiments have been performed as suggested by the software. Engine variable such as loads and blend ratio (Diesel + % JBD) are the most significant variables for brake power at specific fuel consumptions. After experiments, it is reported that the optimized parameters for corrected BP (2.95 KW) are at 100% blend and 10 kg of engine load, and optimized parameter for corrected SFC (0.26 kg/KWh) are at 0% blend and 10 kg engine.
