| description | The main goal of this study is to look at how the development and investigation of on-site production and end-use of green hydrogen as a blended fuel in wet-ethanol operated homogeneous charge compression ignition (HCCI) engine bottoming with ORC and ERC affects engine's energetic and exergetic performances. The exhaust of HCCI engine is utilized to run an ORC turbine which drives the electrolyzer employed for hydrogen production, and the heat rejected from ORC condenser is further utilized to operate an ERC for producing the desired cooling energy. Innovative design and integration increase the engine's thermo-environmental performance and lower hydrogen transport and storage costs. Energy-exergy analyses model is applied to examine the system performance with (0–20%) hydrogen-wet-ethanol mixtures. EES professional software with REFPROP toolbox library data simulated the equation. Adding hydrogen from 5 to 20% improved HCCI engine energy and exergy efficiencies from 41.56% to 44.01% and 37.23%–38.73%, respectively. Using R134a, system efficiencies rise from 42.7% to 48.77% and 37.94%–55.12%. ORC and ERC. The injection of hydrogen from 0 to 20% decreases exergy destruction in HCCI engines from 90.09% to 89% and increases it in catalytic converters from 4.08% to 5.73%. |
