Environmental concerns and attempts to reduce CO2 emission due to greenhouse ga (GHG) include increased consumption of carbon-free fuel like hydrogen and its derivat (like ammonia) in the transportation sector. However, ammonia(NH3), whose storage and carrier requirements suit the existent infrastructure and has better commercial viability, are less expensive in terms of cost per unit of energy and higher volumetric energy density compared to hydrogen. In this study, the potential of NH3 as a ustainable fuel for spark ignition engines with a high compression ratio(CR: 16.5), based on a compression ignition engine architecture, is evaluated after considering NH3 combustion and thermodynamic performance. The experimental results addressed combustion behavior and exhaust gases’ emissions as the possibility of using pure NH3 as fuel on a conventional engine continues to be explored. |
