气缸润滑油自燃诱发低速二冲程氢气发动机早燃实验研究
Experimental Investigation of Pre-ignition Induced by the Auto-ignition of Cylinder Oil Droplets in Low-speed Two-stroke Hydrogen Engines
气缸润滑油自燃被认为是低速二冲程氢气发动机早燃发生的主要原因。基于快速压缩机（RCM）在低速二冲程氢气发动机缸内工况下进行了实验研究。验证了在类似发动机的热力学条件下，单油滴的自燃可以诱导氢气早燃。与天然气发动机相比，氢气发动机的早燃发生时刻更早、最大燃烧压力更高、火焰传播速度更快。并且早燃通常伴随着发动机爆震。过量空气系数(λ)的减小促进了早燃的发生，并伴有不同程度的发动机爆震。在满足热效率的条件下，为避免早燃时产生爆震，过量空气系数为2.5~…查看全部>>
Cylinder lubricating oil is considered the main responsible for the pre-ignition in low-speed two-stroke hydrogen engines. To understand the characteristics of the pre-ignition induced by cylinder oil, experimental research was carried out under in-cylinder conditions of low-speed two-stroke hydrogen engines based on an RCM. The optical experiment verified that the auto-ignition of single oil droplets could induce hydrogen pre-ignition under engine-like ther…查看全部>>
