Fuel consumption of DB605DM, DB, DC....?
« on: August 09, 2003, 08:34:24 AM »
Hi! I am attempting to build some small site dedicated to the Bf 109K-4. It should list what preceeded the K-4, technical details like engine and armament, and operational use.

Right now I am need a bit of help for fuel consumption figures. I only have an incomplete (Sondernotleistung is missing) spec. fuel consumption rate for DB and DC, and nothing for D-2 and DM. Though I can make some very rough estimates, for DC it should be around 600-650lit/h at 2000PS... but I want to list reliable, precise figures, perhaps some of you can help. Help with boost rates would be also great for some of these engines.

I will list here power data, so those can help only need to type a few numbers.

DB605DB
---------
0km,
Sonder: 1850PS /2800rpm/ 1.8ata =
Kampf: 1430PS / 2600 / 1.45ata =
Dauer: 1120PS / 2400 / ??? ata =

6km Sonder: 1600PS / 2800 / 1.8ata =
6.8km Kampf: 1285 PS / 2600 / 1.45ata =
6km Dauer : 1160 PS /2400 / ??? ata =

? km Dauersparleistung ? PS / ? rpm / ? ata =


DB605DC
-------
0km,
Sonder: 2000PS /2800rpm/1.98ata =
Kampf: 1370PS / 2600 / 1.45ata =
Dauer: 1100PS / 2400 / ??? ata =

4.9km Sonder: 1800PS / 2800 / 1.98ata =
6.8km Kampf: 1285 PS / 2600 / 1.45ata =
6km Dauer : 1140 PS /2400 / ? ata =

? km Dauersparleistung ? PS / ? rpm / ? ata =

DB605DM

0km,
Sonder: 1800 PS /2800 ? rpm/ ? ata =
Kampf: 1275 PS / 2600 ? rpm / ? ata =
Dauer: 1050 PS / 2400? rpm / ? ata =

6km? Sonder: 1600PS ? / 2800? rpm / ? ata =
8km Kampf: 1150 PS / 2600? rpm / ? ata =
7.7 km Dauer : 1030 PS / 2400? / ? ata =

? km Dauersparleistung ? / ? / ? =


Not very important, but if someone has consuption or other info for special configurations (like 1.8ata setting for DC), that would be nice, too.

605DC, 1.8ata Sondernotleistnung powers:

With 1.8/1.8ata, C-3fuel
1800PS /2800rpm / 1.8ata =

With 1.8/1.98ata, C-3 fuel but no MW injection
1725PS / 2800rpm / 1.8ata =

Power and consumption with non-methnanol DB605DB config a Notleistung, 1.5ata would be also very interesting!

Thanks for your time and efforts.

This is what I have from Wilkinson (1945) for the DB605A-1:

Best Specific Fuel Consumption is 0.44lbs/HP/Hr that is at the most economical cruise settings.  As a general rule, at military power specific fuel consumption is about twice the best specific fuel consumption.  That is a function of higher RPMs and a fuel to air mixture that is about two times higher.

I have DB 601A-1 data; nothing for the 605d
