[Flightgear-devel] More YASim engine stuff: chilly exhaust

[David Megginson]

I've just added an EGT (exhaust gas temperature) gauge to the pa28-161 
model, and it showed up another YASim engine issue (apologies to Andy for 
posting only about the problems -- the model flies beautifully for the most 
part).

With the engine running at full blast, YASim sets 
/engines/engine[0]/egt-degf to about 58 degF, or 14.5 degC, while the 
outside air temperature is 14.3 degC.  That's one cool exhaust.

I don't know exactly how hot the EGT should be, but I know that it's hotter 
than that.  My plane is heated by a shroud around the muffler, and even the 
heating duct on my floor, a long way from the shroud, is extremely hot to 
the touch.  I'm guessing that we should be seeing exhaust gas temperatures 
at least around 250-350 degF, but I have no solid basis for that guess right 
now.

Is there perhaps just a conversion error in YASim somewhere?

All the best,

David
