The project aims to optimize the fuel injection system for a next-generation hydrogen-ammonia direct injection engine. The use of hydrogen and ammonia in transportation can significantly reduce carbon-based emissions, but it also promotes NOx formation due to its high reactivity and high combustion temperature. To accommodate hydrogen-ammonia combustion, significant modifications are needed in the fuel injection system, including injector and piston design. The proposed study proposes using multiple holes for high-velocity channels to enhance mixing intensity while minimizing mixing scale. This helps reduce NOx emissions and stabilizes the flame by minimizing residence duration and flame temperature. The high-pressure direct injection of gaseous ammonia and hydrogen ensures rapid fuel delivery, maintaining volumetric efficiency and enhancing engine performance. The adaptability of the direct injection method is crucial for controlling combustion performance effectively. The project emphasizes the integration of ammonia-hydrogen direct injection technology, leveraging an optimized fuel injection system through multiple hole injector and piston design for the development of an efficient ammonia-hydrogen direct injection engine.
