Layer of gasses protection

Good afternoon!

I would like toknow more about the layer of gasses that protect the piston, have you more informations about it, a article or a more complete explanation?

Best regards

This is essentially a boundary layer of gasses that protects the crown of the piston and the cylinder head from the full heat of combustion. I'm sorry but I'm not aware of any easy article I can link you to that would explain further.
