摘要
本文着重讨论了在内燃机故障诊断中常用的故障特征量。通过理论和实验方法,对这些故障特征量的敏感性进行了分析。给出了能较好反映故障信息的故障特征量。为内燃机的状态监测与故障诊断提供了依据。
This paper discusses some common fault eigenvalues in the fault diagnosis of internal combustion engines and makes analysis of this eigenvalues by using theoretical and experimental methods. The faulteigenvalues presented are thought to be able to reflect fault information better, therefore laying good foundation for condition detection and fault diagnosis of internal combustion engines.
