FW 190 D what kind of fuel

[twinwasp]

Salve amici
Whatching the pressure gauge on the left top of FW 190 D panel. I was thinking what kind of fuel was used for the Jumo 213 engine. The max rate up to 2,5 ata is very hight for the C2 and more for the B4 fuel . The DB 605 used the C2 for max 1,4 ata. What do you think about the antidetonation problem ?
Cheers.

The Jumo 213A used B4 fuel.

Best regards

I asked also an other question : there weren't any problems referring to the detonation of fuel at so high level of pressure (whatch the maximum value on the pressure gauge).

Wasn't 1.45ata the limit for B4 fuel in the DB605?

In development at wars end was 2.3ata boost for the Ju213 engine.

"The condition representative of standard production Fw 190 D-9’s during 1945 is as follows: Jumo 213A operating at 1.8 ata with B4 fuel & MW 50,..."
In the next paragraph there is a hint at a 2.02 ata use, but no certainty.

Could be the MW 50 continuously used ? As far as i know only in emergency situations.
