Response Surface Methodology Routed Optimization of Performance of Hydroxy Gas Enriched Diesel Fuel in Compression Ignition Engines

In this study, the response surface methodology (RSM) optimization technique was employed for investigating impact of hydroxy gas (HHO) enriched diesel on performance, acoustics, smoke and exhaust emissions compression ignition (CI) engine. The engine operated within HHO flow rate range 0–10 L/min loads 15%, 30%, 45%, 60% 75%. results disclosed that concentration load had a substantial influence variables. Analysis variance (ANOVA) developed quadratic models indicated appropriate fit all models. Moreover, user-defined historical design an experiment identified optimum 8 41% load, with composite desirability 0.733. responses corresponding to optimal study factors were 25.44%, 0.315 kg/kWh, 117.73 ppm, 140.87 99.37 dB, 1.97% brake thermal efficiency (BTE), specific fuel consumption (BSFC), CO, HC, noise, smoke, respectively. absolute percentage errors (APEs) RSM predicted experimental below 5%, which vouched reliable use prediction acoustics emission characteristics along performance CI
