Is it normal that the engines do not cool down even when shut off?

I mean, there's nothing going on in the engine and everything is turned off. How can the engine still be at the exact same temperature?. Even after +30 minutes of waiting?

btw, sorry for my English.

 

while I would think that an engine would hold heat for a while, I agree with you that it takes way too long to cool off, especially from normal operating temperature.

 

Looking at this, it looks like that engine block dissipates only 3J and wind does not change that at all:


There is another funny thing, when BeamNG is on background, there is only 30fps and then 6J is dissipated from engine block to air. Having close to 300fps only 1J dissipates to air:

There is formula which I believe works for calculating effect of wind:

Ah that is good to know, I did presume those are per second.

So 3J @ 60fps becomes total of 180J during one second.

 

If the engine on my car gets fully warmed up, it'll stay warm (above about 60 C) for around 3 hours, and warm to the touch for almost 12 hours, so it might not be so realistic.

According to some rough math, your average aluminum engine block will hold about 108000 Joules of energy per degree Celsius. So it will take quite a while to cool off, especially when it's being insulated by the rest of the engine bay.

 

That's pretty normal, engines are hot things. I'll get my car warmed up, park it for an hour or so and the temp will be a little less than it was an hour ago. It takes a while for engines to cool off.

 

that still is a difference, In beamng the temperature doesn't move a micrometer. I do understand the engines get hot and stuff but I am 100% certain it won't take 20+ hours to get back to more normal temperatures.

 

The engine will stay warm, yes. But the coolant will cool down a lot faster because most of it isn't inside the block when you shut it down.
In sub zero temps you go from 90° coolant to 20-30° in about half an hour.
