Abstract
The increasing demand for sustainable transportation and decentralized power generation requires the integration of renewable fuels into advanced engine systems. This research investigates the combined utilization of green hydrogen and bioethanol in advanced compression ignition (ACI) and common-rail direct injection (CRDI) engines. Hydrogen provides carbon-free combustion with high flame speed, while bioethanol enhances oxidation due to its oxygenated nature. The study evaluates varying hydrogen substitution ratios, ethanol blend percentages, injection pressures, and engine loads. Key parameters such as in-cylinder pressure, heat release rate, brake thermal efficiency (BTE), brake specific fuel consumption (BSFC), and emissions (NOx, CO, CO2, HC, smoke) are analyzed. Optimization techniques including RSM and ANN are proposed to determine optimal operating conditions. The research supports SDG 7, SDG 9, and SDG 13 by advancing carbon-neutral mobility solutions.
