摘　　要：为了研究缸内燃烧火焰对热边界层的影响,研制开发了贯穿式光纤传感器及测量系统,在此基础上初步研究了柴油机气缸内燃烧火焰对缸内壁面的热边界层的影响,结果表明,该传感器可以较好地用于测量缸内壁面热边界层中任一位置的火焰温度。In order to study the influence of combustion flame on the thermal boundary in cylinders, traversing fiber sensor and measuring system were developed. At the same time, the influence of combustion flame on the thermal boundary in cylinders of diesel engine was investigated. The results show that the sensor can be used to measure the flame temperature within the thermal boundary in cylinder.
