摘　　要：通过使用发动机分析仪并采用不同的方法,对发动机瞬时转速进行测量,分析由于转速信号采集频率低,发动机稳定运 转时,所测转速精度能够满足工作要求,而在发动机加、减速运转时,发动机转速有较大的波动,造成转速误差较大。The transient speed measurement method and errors of engine analyzer are discussed by engine analyzers. As a result of collection frequency lowness of speed signal, when the engine runs stably, the measurement accuracy of the speed is capable of meeting the requirement of works; when the engine speeds up or speeds down, engine speeds is fluctuated greatly .the errors of the speed is greater.
