Optimization of combustion characteristics of novel hydrodynamic cavitation based waste cooking oil biodiesel fueled CI engine

Abstract The increment in the usage of automobiles is resulting increased greenhouse gases (GHG) emissions continuously and there a substantial need to reduce them effectively. present research work investigates emission behavior waste cooking oil biodiesel doped with CuO nanoparticles during testing Compression Ignition (CI) engines. This investigation based on effective reduction analysis emitted by diesel fuel experimentation CI It suggests cost modification as prepared from (WCO) novel hydrodynamic cavitation technique which includes reaction mixture composed 1.28 L methanol 10 g KOH 5 preheated WCO at 45 °C reactor for 40 min. These reactants are synthesized utilizing principle final manufactured esterified authenticated ASTM Standard property measurement suitability check. In work, two different investigations carried out. first one, biodiesel-diesel blends 0, 30, 100% (B0, B30, B100) ratio characteristics have investigated 1500 rpm constant speed varying load indicated mean pressure (IMEP). second investigation, suitable blend B30 nanoparticles, keeping other parameters per previous setup, one. For precise results, more experimental trials needed achieve this decrease harmful gases. Using an amalgamation 9 Taguchi response surface methodology (RSM) maximum control minimum number achieved. predefined predictors A (blend), B (load), C (IMEP), where (0 ≤ 100%), 12 kg), IMEP (3.5 7.5 bar) controllable features. Optimization process resulted into CO, CO 2 , NOx appertaining condemnatory merger inputs such B0 (Diesel), kg, 3.48 bar has 0.08 ppm 0.6 30 emission. analysis-based (CuO), including prognosticated results optimization 0.03 0.3 21 current percentage found be 92.3%, 94.82%, 96% compared gases, respectively. coefficient determination almost equal 1, reveals chosen very accurate prediction. provided cost-effective way.
