Power correction for tests in dyno

Power correction for tests in dyno

Power correction for tests in dyno

(OP)
Hi,

I work in a dynamometric bench, testing marine diesel engines, and I would like to find a method to correct the obtained power fixture, comparing the actual pressure, temperature and humidity to the standard conditions.I just could find a formula with the pressure and the temperature.

Thnaks a lot

RE: Power correction for tests in dyno

The information in ISO 3046 is what is used to correct engine power readings to standard conditions. ISO 3046/1 is the reference for corrections for power, fuel and oil consumption measurements, and ISO 3046/3 describes how htose measurments should be taken.

Hope that helps

RE: Power correction for tests in dyno

Tthere is a standard for power factor correction used for assembly line testing that compensates for the density and viscosity of the fuel.
Can't think what the standard number is (SAE 9002 or something similar?) but I know one of the diesel plants in Carolina or somewhere went from lab testing to on line testing (I was visited the site and advised on the online viscosity measurement).
Is this covered in the ISO 3046/3? Does anyone know the standard I refer to?

Thank you two for your time.

I can't get the ISO standards from the ISO web, but I will loo up for a formula in a Diesel engines theory .I'll show it to you so as you can check it out.

I am sure that it is the ISO 3046 rule but I don't know how to get the proper formula to proceed.
Any ideas??
