摘　　要：在一台发动机上利用光纤传感器、压力传感器、振动传感器等对火花点火发动机爆震燃烧进行探测研究，并对测试结果进行比较，同时探索了光纤传感技术在爆震测量中应用的可行性。研究结果表明，光纤传感器与压力传感器在爆震预测与识别上基本等效，但光纤传感器灵敏度与准确度较高，而且光纤传感器还有利于实现其它多项燃烧特性的测试，光纤传感器将成为电控技术中燃烧过程测控信号的重要手段。An attempting investigation for combustion detonation of a spark plug ignition engine is carried out by means of light fibre sensor, pressure sensor and vibration sensor, and results of the investigation compaired. Meanwhile, feasibility of application of light fibre sensor technology in detonation measurement is also explored. Result of investigation shows that light fibre sensor and pressure sensor are practically equivalent in efficiency for detonation forecast and identification, but sensitivity and accuracy of light fibre sensor are higher. Also light fibre sensor has the advantage of implementing many other combustion characteristic tests. So that light fibre sensor will become to be an important means in electronically controlled technology for measurement and control signal in combustion procedure.
