Energy, exergy, exergoeconomic and sustainability analysis of a propane-fueled SI engine operating via flame jet ignition using oxy-hydrogen gas from an on-board alkaline electrolyzer supported by TEG

Key Points

• Enhanced energy efficiency observed in the propane-fueled SI engine, with significant improvements in sustainability metrics.
• The study finds the exergy analysis indicates a 25% increase in performance over conventional systems operated on standard fuels.
• Combining flame jet ignition and oxy-hydrogen gas from an alkaline electrolyzer leads to lower emissions and improved engine reliability.
• Highlighting the potential for exergoeconomic approaches to optimize resource use and cost-effectiveness in engine technologies.
