FW-190 and Oil Temp at Full Power ?

[p6889k]

Can anyone please educate me on how to use Oil Temp gauge on FW-190. It seems that no matter what throttle I apply the gauge stays around 60-70. Even if I go full throttle the temp doesn't change. If I go too long, the engine gets damaged, which is what I expect, but the temp gage still doesn't move. Should it or are they unrelated? If they're unrelated, what do I use the oil temp for? I was thinking that instead of timing how long to go on full throttle, I could make a judgement based on oil temp.

From my experience, when I overstressed the engine it was from having to high RPM for to long. I never managed to overheat an A3.

If you are doing a steep climb on a summermap with full power you should be able to overheat it. But on level flight the A3 stays quite cool.

Oil temp will be under 70...80 °C (apart from some more extreme situations in the summer), because oil cooling is automatically controlled by a special mechanism. So yes, you can have your engine damaged in-game regardless of oil temperature, you can only judge by the time, if i'm not mistaken.

Welcome to IL2 German plane engine models, where the most important instrument to monitor to avoid engine damage is the cockpit clock

AFAIK there is nothing that automatically controls oilcooling in the 190As, exept the radiator in the inlet, that turns with the prop. In the A3 you have low oil temperature, because the air outlet is open. In the A5 you can close the outlet with flaps, but in the game this does not lead that much to higher oil temperatures, but to increasing cylinder head temperatures, which destroy the engine very fast, and without any warning.

 

EDIT: And here the clock won't help you, as you don't know how long it lasts.

Yep, the speed of the ventilator behind the spinner just depends on the motor rpm, but i thought there was a separate mechanism which adjusted the air flow directed to the oil cooler itself. But i'm not an expert on this, so i might be wrong. 

Anyway, one of the FW-190s advantages is that the pilot doesn't really have to worry about all this stuff.

[Yogiflight]

The oilcoolers are located in the ring around the air inlet. But you are right, in the 190s you are free of thoughts about cooling stuff. The only thing you can do is close the outlet flaps in the A5 as far as your engine allows, to get maximum speed.

Yes, the whole ring at the front of the cowling automatically moved back and forth to increase or decrease flow to the oil cooler. The small turbine linked to the propeller shaft is for pushing flow mainly past the cylinder heads, not just the oil cooler.

The reason the oil temperature is "low" is because you're seeing the intake oil temperature, not the outlet temp.

So how can you effectively tell if you are about to cook your engine due to oil temperature issues?

 

I ran the FW190A5 in a quick mission just then at 4.5k alt in winter, closed the oil intake radiators. Oil intake temperature didn't go over 50degc (in fact it I couldn't even tell if the rads were open or closed based on the temp changes alone), yet it destroyed the engine. If I am running without the HUD and tool tips (VR) on there is zero warning? That can't be correct surely?

 

Did real pilots have to watch a timer to tell that they were about to overheat the engine?

My engine failed in winter on WOL server in a 190A5 running 16% oil radiators after about 15-20 minutes of flight. No tool tips were on and the oil intake temps looked fine ~50deg so I was confused as to the destruction of the engine. I use engine RPM instead of ATA in the 190 due to needing to know if i have slipped into combat power so that was fine.

 

Tested again offline winter Stalingrad, and ran the same oil radiator settings with tool tips on, and sure enough, oil overheat followed by engine overheat and very quick failure.

I don't own the A5 but i'm sure it doesn't have an 'oil intake radiator'. Only thing you can adjust manually is the outlet louvres (?) of the main air flow, and if you close them then it probably can cause rising oil temperature. But given that it was 50°C, i don't think it was the cause of the failure (unless it's a bug). Actually I would say 50°C is too low, but i've never heard anything about overcooling engines in this game. 

 

Maybe it's the cylinder head temperature that is the problem here? Would be hard to believe and we don't have a gauge to see but that's my only guess

[=EXPEND=Tripwire]

OK outlet louvres yes, but shouldn't you see a rise in inlet oil temperatures based on cylinder head temperatures rising? The game tool tips fire off a warning about high oil temps, what is cooling the oil back down to 50degrees on inlet if I have the louvres shut?

[rolikiraly]

You should be right, i don't really know how can you cause overheat at any point while having such a low intake temperature.

Maybe someone who can actually try the A5 will be able to provide some insight, so you can understand it better or at least get some tips on how to use it effectively?

[sniperton]

You can overcool the Allison in the P-40, or at least there's a techochat message for it. Mostly happens when you glide in for a landing with idle engine and rads left open. Still, it has not had any consequencies for me so far.

On the other hand, is it not possible that some oil temp gauges simply do not work as they should? I mean you can't rely on what is broken. It seems to me that it's primarily the manifold and the RPM which kills the engine after a preset time, temperature plays little role.

[=EXPEND=Tripwire]

Go give it a try. Quick mission, Winter, Stalingrad. Run Auto level and set cowl inlets to 10%. Time compression to 8x. Your engine should die at around 10-15mins when running combat power yet still be showing cool oil inlet temps. Repeat and run combat power with full open inlets, You will get close to 30mins before failure due to exceeding time at combat engine rating.

 

On a side note, running 85% throttle (edge of tool tips combat/emergency) would destroy the engine around 28mins. Running 84% it runs for about 38mins. Maybe those few seconds of quick mission emergency power @ 100% when you spawn robs you of a few mins at combat as it can't reach 30min.
