| 摘 要： | 对本系统中瞬时转速的采集进行了误差分析,并讨论了影响瞬时转速波动的几个因素,提出测量时发动机平均转速的选取对测量精度有较大影响,进而通过对492Q发动机的故障诊断试验证实了这一点。

| Abstract: | The errors of instantaneous speed collected in this system are analysed,and some factors of affecting transient speed fluctuation are discussed.Then,an idea that the engine's average speed has a big effect on diagnosis accuracy is proposed.At last,the attitude is confirmed on fault diagnosis test of 492Q engine. |

| Keywords: | Engine Transient speed Average speed Characteristic parameter Fault diagnosis |
