Appendix 3 Correction Coefficient Of Power of
Engine
The power of the gas engine decrease very little under the altitude of 1000 meters. It is not
necessary to adjust. When the engine work at the altitude above 2000 meters
，
the power of the
engine or generator will decrease sharply because of the loss of air intake and the speed limit
of the turbocharger . It need to correct. And the correction oefficient table is as follow
：

Note
：
the consumption of gas in above tables aimed to natural gas
（
12T gas according to GB
10847
），
if the fuel is methane or CBM or others
，
the data of correction coefficient in above
tables were as a reference.
