Exhaust valve thermal gradient
Exhaust valve thermal gradient
(OP)
Hi all
I was wondering if anyone could help , I need the average temperature gradient (in an Air cooled gasoline Engine) of the Exhaust valve
Hope some one can steer me onto the right path
Kind regards Stephen

RE: Exhaust valve thermal gradient
It can run as much as 1150 F at the face area, and 1450 towards the center with out. And with sodium 1150 at face, and 1100 at the center. This in an aircraft engine.

Sodium is fine
Its very difficult to find such info on the internet, I would have though this one would have been easy to find !!!!
Thanks very valuable post
Kind Regards Stephen

And I suppose there are some variables to that. Such as guide to stem clearances etc.
