摘要

聚氧二甲基醚（PODEn）因其高氧含量而被认为是一种很有前途的燃料，当与氢（H2）结合在反应控制压缩点火（RCCI）燃烧方法中时，它在提高效率和减少排放方面显示出巨大的潜力。本研究分析了不同喷射方式对H2/PODEn RCCI燃烧性能的影响。结果表明，劈开喷射PODEn可以改善混合气的分层和反应性分布，从而降低峰值放热率（HRR），缓解爆震倾向，提高燃烧稳定性。延迟主喷射时间（SOIma - l - n）和优化先导喷射量比（RPI）可以有效控制燃烧相位和低温放热过程，从而提高指示热效率（ITE），同时减少NOx排放。此外，适度增加预混比（PR）可以加快燃烧速度，进一步提高稳定性。这些发现为H2/PODEn RCCI发动机的高效清洁运行提供了重要见解，为未来发动机设计和控制策略提供了理论支持和实践指导。

Experimental investigation of hydrogen-PODEn RCCI combustion: Influence of split injection strategy and hydrogen ratio on engine performance

Polyoxymethylene dimethyl ether (PODE_n), recognized as a promising fuel attributed to its high oxygen content, demonstrates significant potential in improving efficiency and reducing emissions when combined with hydrogen (H₂) in the reactivity-controlled compression ignition (RCCI) combustion method. This research analyzes the influence of various injection modes on the combustion properties of H₂/PODE_n RCCI. The findings indicate that the split injection of PODE_n can improve the mixture stratification and reactivity distribution, resulting in a reduction in peak heat release rate (HRR), mitigation of knocking tendency, and enhanced combustion stability. Delaying the main start of injection (SOI_maᵢ_n) timing and optimizing the pilot-injection quantity ratio (R_PI) are effective in controlling combustion phasing and the low-temperature heat release (LTHR) process, thereby improving indicated thermal efficiency (ITE) while reducing NO_x emissions. Additionally, a moderately increased premixed ratio (PR) accelerates combustion rates and further improves stability. These findings offer key insights for the efficient and clean operation of H₂/PODE_n RCCI engines, providing both theoretical support and practical guidance for future engine design and control strategies.
