Overcooling

[greybeard1]

After detailed modeling of overheating in 4.11, I think next step (quite necessary to get the whole matter modeled and not just the upper part) should be overcooling.

It was in reality an issue and P-38 flight manual, for instance, set a minimal working temperature of 40°C for lubricating oil, whilst P-47 pilot's manual has a nice illustration showing pilot leaning out his cockpit, trying desperately to heat his overcooled engine, covered with ice, by a lighter...

What about this?

Thanks for all work done so far, cheers,
