增压柴油机无负荷测功系统的研究

Research of the System about Power Measurement of Turbocharged Diesel Engine at No External Load

详细推导了增压柴油机无负荷测功所用的理论公式。为了验证该理论的正确性,设计了基于该理论的无负荷测功系统,并利用该系统对不同发动机在不同工况下进行了无负荷测功试验。结果表明,该无负荷测功系统与台架试验结果之间的差距在5%之内,从而验证了该理论是正确的。

We deduced the particular theory for power measurement of turbocharged diesel engine, To approve the validity of this theory, we have designed the power measurement system based on this theory. With the experiment based on this system, we can see that the difference between the system and the test bed is no much than 5%, so we can say that the theory that we have deduced is right.
