Corrected fuel consumption
Corrected fuel consumption
(OP)
I am familiar with the methods of correcting power for ambient test conditions but how is this done for fuel consumption, particularly gaseous fuels? Is this addressed in the various correction methods (ISO, SAE, DIN, JIS, etc...)?
Corrected (brake-specific) fuel consumption isn't as simple as dividing your corrected power (bhp) by the fuel flow rate (g/bhp-hr or Btu/bhp-hr), is it? I'd think this would yield inflated economy figures... How do you find corrected fuel rate?

In a car being driven on a road, air density will also effect aero and then it gets real complicated.

Black2003cobra confirmed my intuitions. I'd think this linear relationship would hold within the acceptable operating limits of the engine.
Maybe the manufacturer has some proprietary formula worked out or they're talking about correcting for the fuel gas composition and not ambient air conditions.

When doing power plant commissioning and some larger gas compression systems this was the reference and procedures we used. Also look at ISO 3046-3 for reference on test measurements.
Hope that helps
