Coolant temp.

[Kosm1cznY]

Why coolant temp is not hmmm how to put it well?
Why it is not properly simulated?

[Jaidensky]

What exactly isn’t simulated well? It seems to be the best simulation I’ve ever seen in a game…

You mean coolant temp simulation? Well it is not.

I love how devs approach to make this game and I love how much stuff is simulated about vehicles in this game. That is why I wanted to point out lack of proper simulation in this exact thing.
I do not know if this is placeholder ETC. but IMO it is not the hardest thing to tweak and game is in development for quite long time now.
I noticed that coolant temp acts weird some time ago already but after recent test I see that it is somehow forgoten to be modeled more trully to real life counterpart.

You still haven’t answered my question. What about it exactly isn’t modeled realistically? How exactly does it act “weird”

[Kosm1cznY]

You really nerer observed how it works?
Do you use option that car engine start as pre heated aldeady??

[heavygunnertty]

yeah the fact that you need to drive fast to get any temps is odd but i think they will fix that eventually not a priority

It all seems realistic to me. Still havent answered my first question.

Well are you a dev team member? I can only explain this to dev team for them to work on it.
See Jeremy Clarkson noticed weird design in cooling system too.
Why you do not go and test it on your own. Instead you demand explanation. I am not obliged to give you exact description about this issue.
You own this game too. Why you do not spend about 10 minutes to see what is not working as it should be.

First of all, i am currently not able to play the game (part of the reason why i asked,) but mainly if you find that the mechanics are "weird" and you don't know how, how does that make sense? You seem to be doing everything you can to avoid this question, which should be simple and easy to answer since you clearly know it isn't simulated well.

Agreed. If you drive hard and overheat the coolant (130C) the coolant will suddenly become adiabatic(coolant heat transfer to air becomes 0Joule/s). And you have to wait half an hour to cool down unless you drive into water.
If you look into the combustionEngineThermals.lua, you can find that when the coolant reaches 130C, the cooling "efficiency" becomes exactly zero. This is not true because most of the car radiator cooling water tank has expansion volume and a pressure relief valve to maintain a constant pressure or overpressure to make the coolant "boil over" at a constant pressure while maintaining cooling efficiency until most coolant are evaporated(until then, the coolant efficiency won't drop drastically). Not to mention evaporation/boiling is an endothermic process.

Well said and described

Ok fair enough that you have no ability to test anything at this moment.
So, I will focus on basics and try to get it short.

If you drove real car in real life you must know basics.
So, as we start engine, it gets worm right?
Two basic ways are:
1. iddling (car is stationary)
2. Driving at normal pace without overreving the engine.

Real car while iddling will slowly warm up. Thermostat kicks in at set point to hold steady temp around 90 degress C.

BeamNG car engine will never warm up while iddling.

Real car While normal driving, deppending on engine size example 1.6 litre will get worm faster than 3.0 litre. Smaller engines will warm up faster. Simple right?

BeamNG cars no matter what engine, will warm up VERY slowly while normal cruising.

All engines in BeamNG while racing pace (reving high) will warm up faster.

I hope it is enough for you to understand that BeamNG have very simplified engine cooling system.

Have you ever driven a car IRL with the thermostat jammed in open position?
I used to have such a car, the temp gauge never moved until late spring/early summer.
The radiator cooled constantly. I had to put a piece of cardboard in front of the radiator to get reasonable temps.

Maybe BeamNg don't simulate a thermostat?

LMAO.
Design game to simutate broken thermostat In all vehicles present in game... All the time

That would make huge ammount of sense.

I owned some cars. I am into cars. I know how they work and what kind of damage can occurte. Seriously you consider that dev decided to mage simutation game that have aslo cooling fluid temp simulation and then decide that all cars will have broken thermostat?
Seriously?!

[robert.norgren]

It's the same behaviour YOU describe. Very slow temp increase under low power load.

Is there any line in the car files that describe how a thermostat would be simulated?
Edit: Ok, there is a line setting the thermostat to 90 deg C.
Maybe to much of the temp is taken up by the block and oil.

Have anyone an idea at what temp the gauge is starting to show? On my cars the gauge most of the time doesn't start untill 60 deg c.

In most cars it is about 40-70 C.
