Parametric Optimization of Emission and Performace Characteristics of Ci Engine Fueled with Hydrogen-Enriched Microalgae Biodiesel Using Taguchi

Abstract

CI engine combustion, performance, and emissions are impacted significantly by injection parameters such as Injection Angle, EGR, and Load. The emission and performance characteristics of a single four-stroke cylinder CRD engine fueled with micro algae biodiesel blends of 30% (MA30H2) and flow rate of hydrogen 7lpm. The investigation is carried out for three distinct injection advance angle 15°, 20°, 25°, EGR 0%, 10%, 20% and applied loads on engine 0N, 6N, 12N, 18N, 21N, 24N. From the results of experimentation, input parameters are optimized using Taguchi method. The analytical results indicates that Injection Angle has major impact on minimizing CO, HC and BSFC, Load has significant impact on minimizing NOx, CO₂ and maximizing BTE. EGR has minimal impact on the emission and performance characteristics. The optimal parameters Injection Angle, Load and EGR vary for all the characteristics.
