Alternative fuels are the need of the current situation as conventional fuels are depleting very quickly and causing increase in amounts of pollution. Hydrogen as a clean fuel with Higher Calorific Value plays important role in increasing combustion characteristics. When compared with the performance of ethanol as a fuel, ethanolhydrogen blends have demonstrated a 5% increase in power production, 15% reduction in hydrocarbon emissions, and 12% reduction in carbon dioxide emissions. All tests are conducted at speed of 2500, 3000, 3500, 4000, and 4500 rpm with the Wide-Open-Throttle (WOT) condition. CO & HC emissions are reduced using ethanol, whereas hydrogen addition enhanced the decreased power output, higher brake-specific fuel consumption and in cylinder pressure.

Abstract


Alternative fuels are the need of the current situation as conventional fuels are depleting very quickly and causing increase in amounts of pollution. Hydrogen as a clean fuel with Higher Calorific Value plays important role in increasing combustion characteristics. When compared with the performance of ethanol as a fuel, ethanolhydrogen blends have demonstrated a 5% increase in power production, 15% reduction in hydrocarbon emissions, and 12% reduction in carbon dioxide emissions. All tests are conducted at speed of 2500, 3000, 3500, 4000, and 4500 rpm with the Wide-Open-Throttle (WOT) condition. CO & HC emissions are reduced using ethanol, whereas hydrogen addition enhanced the decreased power output, higher brake-specific fuel consumption and in cylinder pressure.
