摘要

摘要:
为提高摆盘发动机的循环热效率和输出功率，建立预燃室氢射流点燃氨的摆盘发动机仿真模型，分析预燃室关键结构参数对预燃室内热射流和发动机性能参数的影响。结果表明：适当地增大截面比，可使热射流起始时间提前，且热射流贯穿长度增加；当截面比达到0.225时，缸内火焰传播速度更快，综合效果最好。随着预燃室容积的增大，射流火焰的贯穿距离和分布面积呈现先增后减的趋势；当容积比为1%时，射流火焰贯穿距离更大，分布面积更大，使得发动机在该工况下的动力输出与经济性达到最佳平衡。喷孔直径对于摆盘发动机性能的影响同样呈现随喷孔直径增加先增大后减小的趋势；喷孔直径为1 mm时，主燃烧室火焰传播速度更快，分布面积更大，综合性能更优。为摆盘发动机的预燃室结构优化设计及氢氨燃料的高效应用提供了理论参考与技术支撑。

Abstract:
To improve the cycle thermal efficiency and output power of the swashplate engine, a simulation model of a swashplate engine with pre-chamber hydrogen jet igniting ammonia was established. The influences of key structural parameters of the pre-chamber on the thermal jet in the pre-chamber and the engine performance parameters were analyzed. The results showed that appropriately increasing the cross-sectional ratio can advance the start time of the thermal jet and increase the penetration length of the thermal jet; when the cross-sectional ratio reached 0.225, the flame propagation speed in the cylinder was faster, and the comprehensive effect was the best. With the increase of the pre-chamber volume, the penetration distance and distribution area of the jet flame first increased and then decreased; when the volume ratio was 1%, the jet flame had a larger penetration distance and a larger distribution area, enabling the engine to achieve optimal balance between power output and economy under this working condition. The influence of the orifice diameter on the performance of the Swashplate engine also showed a trend of first increasing and then decreasing with the increase of the orifice diameter; when the orifice diameter was 1 mm, the flame propagation speed in the main combustion chamber was faster, the distribution area was larger, and the comprehensive performance was better. This could provide theoretical reference and technical support for the optimal design of the pre-chamber structure of the swashplate engine and the efficient application of hydrogen-ammonia fuel.
