发动机无外载加速测功功率折算系数的推导与应用

The Derivation and Application of the Power Conversion Coefficient of Engine Power Measuring under No-load Speeding-up

本文阐述了发动机无外载加速测功功率折算系数的理论推导和测定方法,通过对比试验,论证了发动机无外载加速测功的可行性以及在故障诊断中的应用。

The theory of the power conversion coefficient of engine power measuring under no- load speeding-up is introduced in this paper.Meanwhile the feasibility of engine power measuring under no-load speeding-up and its application in trouble diagnosis are demonstrated by comparison experiments.
