9:10 The radiator is cool because there is no coolant flowing through it. It will cool itself to ambient temperature, but if the engine doesn't exchange any fluid with the radiator, then the engine will not be cooled. General rule of thumb: The hotter the radiator, the more cooling is happening. Have a close look on the flow rates, you will notice a causation between high radiator temps and high flow rates. Also: The Temperature of prefab engines is only dependent on rps and ambient temperature. Fuel burn rate or load or throttle or anything else has no affect on the engines. They can run at full throttle without any cooling at around 12 rps. You can gear them in such a way that they will stay below 12 rps with full throttle and get more power out of them. This is obviously only necessary until the devs fix the issues.
At 9:40 in the video, the engine temperature was actually dropping because the engine was pumping out the hot coolant and not sending it through the radiator, when you opened the valve to let the coolant out, and looked at the temp, it was at 105.8 and it dropped to around 104.7 if you left it on the temp would have kept dropping.
Been messing with my oil refinery and found oil had to be 6-8atm before it would start heating. Did you try pumping a small or medium tanks worth of water into the cooling loop before activating the engine.
Hmm, great minds think alike. Was testing cooling / heating systems (for other reasons) earlier and posted on your Discord (insert shameless plug here) some results. One interesting thing, radiators will heat up the room they are in. Need to test if engines also heat the room. In any case, you may find your radiators work better if placed outside of the engine room where there is plenty of airflow or even places outside.
So, odd question, but on the back of the furnaces I think it says coolant in/out and uses crude oil for refining. Can you use crude as an engine coolant in game? If so, is it better or worse? I plan to test this, but I'd appreciate any help or suggestions
The actual throttle amount doesn't matter, it's the engine rps. Anything over 12 is just going to be harder to keep cool for right now. Add more load to lower the rps to 12 or below at full throttle and it's work just fine.
So I have been playing with reactors and found pressurizing the reactor with air to about 34.5 atm gave me best flowrate. It was changing flowrate by a couple hundred L/s. This was closed loop setup and large pumps on supply and return from boiler. Boiler heated fastest with better flowrates.
The radiators were affected normally, you need tons of air flowing through them to make them effective. Being stationary won’t do a think even though they are electric, the fan just can’t draw in enough air. If that engine was on a plane and moving fast, the radiator would be able to cool it down easily, there just isn’t enough air flowing through the radiator to cool the engine down.
The game isn't that sophisticated. The "fans" are just a toggle to increasing the heat transfer rate. Basically a switchbox between two different numbers. Ambient temp controls how fast heat transfers out of the radiator. There is a lower ambient temp at altitude--I've run tests and it averages -0.007 deg/m above sea level. So at 1000m, the air temp will be 7 deg cooler than the ground temp.
Hello, From Looking at how you cool engines in my opinion I feel like you are not giving the engines enough cooling in the first place. I understand that these systems worked before the update but I always overloaded on cooling for my engines (especially Modular) which meant that after the pressure update I have seen that my cooling has some how gotten even better. All I would say is that if you want to keep using 1 rad is to make the lines in-between the engine cooling ports and the rad as short and as straight as possible, and also adding in 2 big pumps as it seems that they have nerfed the small pumps, if the large pumps don't seem to be creating a large amount of pressure, then I recommend having a bleed of valve with a gas filter, this makes no sense but I have seen it fix this issue from time to time. Also instead of taking water directly from the sea floor, I recommend putting it through a 5x5 heat exchanger with 2 large pumps on either side, also instead of doing A,A and B,B like you are currently, I would recommend A.B for The engine side and A,B for the ocean side, this should make the pipes shorter and make it more efficient I think.
Medium engine solution: two small pump pump in another pump and that pump to strait to the engine, work only for boat with Sea water cooling and for the pipes do not put t junction just straight and 90° for the output of the engine just a fluid port, I can run my engine at 20 rps continue
It's really weird, sometimes gas relief valves help and sometimes they don't, as far as I've found out the more stable and high the flow rate is the better the cooling
I think the notion that there is a broader "dev intent" is foolish. To me it appears to be "throw parameters and equations at the wall and see what sticks". The problem with under-modeled, undocumented systems like Stormworks is that the emergent behaviors approach randomness. If the game had been constructed from the start with something closer to real-world physics, it wouldn't be so hard to balance, because physics would already be "documented" and we could make engineering predictions.

I actually noticed this while rewatching the video - I will look into this again!

Nice new ship capabilities. That's going to be a great unit out on the water. 😎

Wow, watching to the end is definetly worth it on this one

Yo can you read my? May you can find a solution

Nice surprise at the end! 😁

I will look into this as well! Thanks for the idea

how about cooling the air inlet? is that possible? that may cause the engine to run cooler.
Discovering Intercoolers in Stormworks.
You need to compress the liquid probably at 16psi like a real cars coolant system.

Are u gonna make any more omua vehicles

The weird is the engine more you run more is cooler need just little of time after the pump are on
Conclusion more cooling flow as possible
In theory you want your radiator pressure to be the highest and the inlet to motor the lowest.

what if u set up alot of heat exchange (like air) in a chain wold that work?
If i put my fast passenger Liner on the workshop will someone take a look at it and see what is wrong with the engines?
Dang I think it is there is pressure in the pipes or that there is too little
"Rat"
Also, nice tutorial
Can u play a pin
