are engines broken again? and a spawning bug

[Grimmsfan]

I am using a modular engine that i made for one of my first proper ships, it has always had *some* issues overheating, but ive always been able to reduce RPS and eventually it cools, well... I put it in a new ship, all pumps are hooked up, power is ran through correctly, everything should in theory work right. But it overheats every time, not the standard reduce RPS to 12 and it fixes itself, the lowest the RPS can go is 10 with gearboxes before it stalls out, and even then it is still heating up, it has gotten over 97 degrees at 10 RPS, I thought this issue was solved with the fix to the compressed gasses overheating bug since, and it largely seemed to be till now. As stated I have pushed it as low as 10 RPS, and thats also with 6 or the bigger pumps using ocean water to cool, its like they just dont cool the engine. and this isnt like the pumpjack thing where i overlooked a crooked enclosed pipe, ive already checked all pipes, cylinder rows are also connected by manifolds and should be sharing coolant. it uses 12 to 24 medium cylinders in a radial form. I say 12 to 24 before the base model has 12 and was made to be expandable, I have as of recent had issues from counts of 12, 20, and 24, with no attempts at further increments.

as for the spawning bug, when i spawn in my ships, planes, etc., sometimes they act like they have phantom builds underneath them, like they are sitting on top of another copy of themselves that cant be seen, interacted with, or stepped through. I've also noticed that when this happens the game saving icon in the corner never goes away and wont let me quit, manually save, or much else. in one instance i was able to go into the workbench to save my build, in another instance i could not move at all except to look around. all other instances all seems fine save the phantom physics and inability to interact with UI.

If anyone else is experiencing either of these or has advise I'd like to hear it, thank you.

For the cooling:
Seawater-cooling is now (after Spacve DLC) to most less effective cooling-method (was the best before Space DLC).
Regardless of small pump or big pump, they are not able to pump in more than 10 l/s from the sea.(befor 35 - 70 l/s).
I have opened a bug regarding the 10 l/s issue, and the answer was in short form:
"Deal with it, that's the new standard because of pressure based algos...".

So... the best way for now, I found are the 5x5 fan-radiators(+ 1 pump).
Heat-sinks might be the more realsistic option (heat-sink below the boat...touching the sea-water), but the radiators are still more efficient.

thank you. i was afraid it was something like that. And Merry Christmas, or Happy Holidays if that better suits you!

problem. neither the radiators or heat sinks have done anything. still overheats after going no more than 2.5 Km. whats weird is the radiator say they are only 36 degrees in detail mode while the engine is at 97. thats with and without water tank and with and without pump. electric is hooked up and they are turned on. the devs really just need to get a handle on this, its no fun to spend over a week working on a destroyer just to have its range be 2.5 Km before it needs a 20 or more minute breather. I'd let it borrow my inhaler, but the air flow seems in working order.

no matter... thanks for the suggestion, even if the game still hates engines.

Make sure that you have a consistent flow-rate within the cooling-manifold(s).
Other new issue, which might could casue issues..the electric valves.
You need to have power at well over 94 percent to have them working as expected.
I.e at 89 percent, my valves showed "on", but were closed until my battery went to >95 percent.
Best use a battery-charger before critical components like important valves and cooling-pumps.

I am just back from a 1 hour test-trip with my sub.
Here the diesel runs all the time underwater using 2 3x3 electric radiators.
The engine has 2 cylinder 3x3. I am using only one small pump per loop.
This gives me a flow-rate of about 130 l/s...which is much more compared to pre Space DLC.

The engine is set to 23 RPS and goes down to 11 RPS as soon as the cliutch to the generators are closed.
After about one hour I have had 104 degrees steady. Not the best, but ok within a closed loop.
I tested this within the southern part of the map (so about 29 degrees env temp).

Again, make sure you have a steady/stable flow when looking at your cooling-manifold.

...and...you too....Merry Christmas :-)

its not just the flow, i have a small engine with 2 5x5 L to L Heatexchangers, a pump for each in and out so 4 overall, the flow is study, Coolant temp in exchanger is 12°, the coolant manifold ist at chilling 26°, the Zylinders are right now at 96° and still climing. at 15 RPS...that is just STUPID :D

I agree that the engines in general should run with higher rps than just 10-11 to avoid overheating. I mean for the very large ships like VLC supertankers, it's nomral that they run below 80 RPM's. But this are the really big ones. So the 5x5 running at lower rps would be ok, but not for i.e. the 1x1.

Btw, the liquid-to-liquid heat-exchangers have (had) some issue, where the cylinder-side must be on the B-loop to have some kind of cooling. Not sure if this is still the case.
I didn't have nice results with this setup in the past, so I switched to the electric-radiators in my sub (which is a bit unrealistic..but works for me).

Could you give us more details?
What kind of engine controller are you using? If the Air/Fuel ratio is not ideal, it will produce an excessive amount of heat.
How many cooling devices, and how many per cylinder?
Four 5x5 electric radiators can cool a 3 cyl 3x3 at 15 RPS, and four liquid heatsinks at the bottom of the hull will cool the same engine, but with 12.5 RPS max.
It is important that you have the proper liquid flow rate. It should be above 100 l/s, and steady. Ideally 150+ l/s.
Do not add junctions in the pipe to parallel the radiators, this will cut down the flow rate and, despite there being more cooling devices, it will NOT cool much better.
Give them their own cooling manifold and pump.
If you must use more than one in a loop, such as I did with the liquid heatsinks (2 pairs in series w/separate pump for each series pair), it is best to plumb them in series, and no more than a few because as the temperature difference decreases, cooling will decrease.
