Yeah that's all good regarding BoB, been reading through it as well and I actually contributed with Spitfire and Hurricane fuel system problems in CloD.

The above is regarding Bf 109E which had 2 separate gauges, one for oil and one for water temperature. The oil temp was also switchable between inlet and outlet temperature, but this is not correctly modelled in CloD. This is also the case for Il-2 - oil temp gauge is showing outlet temperature only.

Later 109 models (F-2 - G-14 in Il-2) only have one gauge in game as I explained before. K-4 has got 2 separate instruments again.

I hope you can understand me, despite my bad English

No worries, I understand.

As per 4.11 guide, water (or CHT) temp is more depending on MFP, oil temp more on your revs. 109s have got no manual prop. pitch (as RPM control) and as I stated above, on automatic PP, water 115 means oil some 80 (that is inlet temp). There are no issues with the 109s regarding temperatures except for the water / oil switchable instrument not being modelled (yet).

As it has been stated before, MW50 will be looked at in the future.

As for the rest, it's matter of opinion. Il-2 is becoming less of a game and more of a sim. You can still disable the new features if you wish.

Anyway the MW50 is wrong modelled in IL2, only the DB605DC engine could use the WEP (I mean 110% power) without MW50, so the Bf109G-10, G-14, G-6 AS can't use 110% power without MW 50, only the K-4 C3 could use 110% power without MW50

Well, I don't sure wich engine the G-10 used in game but I think it used the DB engine, so B4 fuel with MW50.

MAYBE IT CAN HELP

1) Only DB605A and DB605AS use only B4 Fuel and dont have MW50 = (G6 - G6/U2 - G6/U4 - G6/U4/AS - G6/AS - G6/U2/AS) , But they can use 110% of power allowed / and optional + GM-1
2)All other BF 109 must be modeled with C3 fuel + MW50- the can use it !!!!
Most of the BF 109 in game, are not modeled for proper performance with C3 or C3+MW50

3)The exepcions are;
DB605 D-2, this engine was not mass produced
And (G14/AS - G14/U4/AS - G10 - G10/U4) they can use B4 + MW50 - 110% of power allowed - and/or C3 + MW50 -110% of power allowed

We have only the "castrated" BF 109 in game, te exeption is BF 109 K4 C3.
Always made ​​the worst choice for modeling the BF 109. ???





If someone can show something like this.
For the FW 190 "A" "G" "F" and all its sub-variants with boost
I'll be Very happy!

The BF 109 is difficult to understand
At least all FW 190 use C3 fuel
I think there are many things about FW 190, that can not be easily simplified.
Only I think ...

I think this table is a bit wrong, if you read this page,at the table's end you will find this line (for the DB605ASM):

Das Triebwerk Daimler Benz DB 605 ASM entsprach dem Ausgangmuster
DB 605 AS, wurde jedoch im Gegensatz zu diesem Verbesserung der Start-
und Notleistung mit dem Sonderkraftstoff C 3 und zusätzlicher Wasser
Methanol-Einspritzung geflogen (MW 50).


Roughly it say:

The ASM is the sameas the AS but with improved Special Emergency power designed to run with C3 fuel and MW50

The same is for AM engine

Only the DB/DC engine colud use B4 or C3 fuel

DB/DC engine are the same with just a different setting, you can change this setting with simple screwdriver

Thanks !

If you PM me I will send you an usefull original DB605 datasheet that cover all the engines.
As I already said all the MW50 equipped (except DB/DC and ASB/ASC) need C3 fuel,them can't run max boost without C3 and MW50.
There is a switch that enable the MW50 when the throttle is 110% open.

Probable SM/ASM could run with B4 and without MW50 but with B4 them are the same as A/AS, less boost, less power.

Clearly is quite strange that an DB605A engine could run it's max boost for 5 minutes when an DB605AM could run it's max boost (it mean with MW50) for 10 minutes.
Probable it mean that with MW50 an engine could endure more time at his max boost

I found an interesting article aboutBf109K-4, C3 and MW50:

The AM could use B-4 as well with maximum power (1.7ata), a G-14 MW 50 manual mentions that while C-3 is preferred as normal fuel, its possible to use B-4 in emergency with MW-50. It was more risky than using straight C-3 and MW 50 combo, since any failure in the MW system meant that the engine would immidiately start knocking and self destroy in short order. B-4 alone could not take the compression at 1.7 ata without detonation, while C-3 could. I have not seen a similar manual for the ASM but its a rather safe bet it worked the same, given the minimal difference (supercharger) between the AM and ASM.
