With the implementation of global carbon reduction policies, there has been a growing emphasis on the research of zero-carbon fuels. Both ammonia and hydrogen, as zero-carbon fuels for internal combustion engines, come with their own set of advantages and disadvantages. Jet ignition, known for its high ignition energy and rapid flame propagation velocity, offers a more effective ignition means of combining ammonia and hydrogen than spark ignition for use in the engine. This paper, while maintaining the lambda value of 1, conducted a numerical study to assess the impact of various prechamber structures on the combustion characteristics of an ammonia/hydrogen engine. Firstly, the nozzles angle emerges as a critical parameter in the design of active prechamber structures.
