109 E4 Engine Temp Question

[BM357_TinMan]

This may apply to other 109 E's as well but, I was wondering.

Even with the oil and water radiator flaps wide open, the temp gauges read "red lIne" pretty much at any ata under the red line ata.

is this correct?

Also, the fuel pressure gauge reads high outside the indicated limits.

This isn't as much as critic critique as it is more a question of, "is this really how the 109 E ran?

Maximum temperature for the 109's in game is 100 degrees for coolant and 105 degrees for oil.

 

Normally you want the coolant at 95 C or less, and oil at the same.

 

You can exceed that, in fact you run at 100 C in some instances, but you have a chance of blowing your radiator or having a mechanical failure.

 

In the case of oil temps, even if you don't exceed 105 C, you will see some negative effects if temps are close... horsepower will decrease due to the reduction in viscosity.

 

So it is best not to exceed 100 C with oil temps.

 

A combination of high water and oil temps will likely result in failures.

 

Regarding historicity:

 

The early 109s and other German types were unusual in that they had unpressurized radiators... so while the above figures are historically correct for sea level, max allowable temps decreased as altitude was gained.  So max temps might be 75 degrees at very high alts.  The game does not model for unpressurized engines as most aircraft went the pressurized route after 1940.

Ok.....Thanks for the reply but, the actual post/question dealt with the fact that, in the game, these temps ride right on the red line (about 95° I think - I'm not home and can't check) and do not move much even with the radiator flaps (both oil and water) wide open or adjustment of ata or airspeed.

Are you using full real engine management?

 

If you have the full engine difficulty on, you will find the temp gauges do move and you will have to open and close the rad and oil cooler to get max performance.

I thought I was.  I'll have to check when I get home.

I think somothing is wrong with temperatures in Bf-109E now.

In 4.312 it works different than now in 4.5

 

Dive: open full oil and water radiator, minimum prop, minimum pitch - temperatures stay near on the same level (near red/white lines),

how is possible? In this time I forced maximum coolant and temperatures must be near 40-50 maximum. 

 

Example:

 

5000 meters:

 

 

Near the ground:
