DB605AS info - need to determine WHERE and WHEN?
 

Hi guys,

Got a DB605 ASO I am trying to figure out who, when, and where it was built. I beleive it was hsg (Dieck, W., Werk 1, Apparatebauanstalt, Aussig-Türmitz/Sud)…but any info would be great!

Also, what is teh differnece between the ASM and ASO??

Hello Mike,

I've studied a bit the DB 605 serials. The "007" in the serial number of your DB 605 ASO indicates in general a DB 605 A from the Daimler-Benz Motoren GmbH, Genshagen Kreis Teltow (production code hsq). Interesting for me is your production code hsg of the W. Dieck, Apparatebauanstalt, Werk 1, Aussig-Türmitz/Süd. Please check once again the stamping, perhaps the g is a q. On the other hand, perhaps the W. Dieck Werk was a subcontractor of the Daimler-Benz Motoren GmbH, and assembeld engines for them. I have another DB 605 serial close to yours (DB 605 A-1 007/07111 from the Bf 109G-6/U2 WNr.412951) also with the producer code hsg. Until now I thought is was a typing/transfer error, but now you could clear this up.
Can you please send me a bigger scan of the production plate?

best regards,
Tomislav

The "O" in the ASO engine designation stands for "octane select", which means it could use both B4 and C3 fuel. The ASM is a DB 605 A with enlarged superscharger intake (S) and MW50 methanol-water injection device (M), uses C3 fuel.

IMHO, It's AS-0, i.e. Nullseries.

I've seen flight reports with this designation, as well as some with AS-1.

Hello Ivan,

You could be right! The serial number of the above DB605 is closer to the serials of "regular" DB 605 A's then the late war DB 605 ASMO's.

thanks,
Tomislav

Hi Guys!

From what I found out, hsg is Dieck, W., Werk 1, Apparatebauanstalt, Aussig-Türmitz/Sud. Will have to view if it is hsq and get back to you.

Will get a close-up of the tag...


So...a 605 ASO is nothing more than a 605A...but could take both fuels? So no MW50 and enlarged intake? Tomislav, you mention "S" stand for enlarged "S"upercharger, and "M" meaning "M"ethanol...however Supercharger in German is "Lader". So...is there an actual German determination for the "S"?

As this is an ASO, would that not make it an A with the enlarged Supercharger and NO MW50? also, could it take the MIXED B4/C3?

Greetings all,

Regarding DB 605 ASO, WNr. 007 007288, I have several engines with WNrn. close to this example in my database files, four of which are listed as “ASO.”

ASO 007 06105
ASO 007 06171
ASO 007 06287
ASO 007 06288

Most of these are listed as being built by Daimler-Benz Motoren, Genschagen Kreis Tetlow, with the Hersteller code “hsq.” However, as Tomislav correctly points out, some sources list their Hersteller codes as “hsg.” I have always assumed that this was just a typo or misreading of the codes by the documenters…but who knows? The engines above and below these ASO numbers are “normal” A-1s.

More ASOs are found in the following series:

ASO 007 0952?
ASO 007 09767
ASO 007 09822
ASO 007 09842
ASO 007 10020

I also have several ASMOs interspersed among a long list of A-1s:

ASMO 007 10942
ASMO 007 11138
ASMO 007 11234
ASMO 007 11476
ASMO 007 11622

Interestingly, and reflecting the fact that DB 605 ASs were rebuilt from DB 605 A-1s, many of these ASOs also displayed three, four or five digit “rebuild” numbers.

@ Mike
Your DB 605 is definitely an AS (DB 605 A + enlarged supercharger intake). The "S" stands for Sonder (german for special, but refering to the different supercharger intake).

@ Steve
I have three more ASMO's to add to your list
ASMO 007 10179
ASMO 007 10829
ASMO 007 10938

Perhaps someone with more technical knowlage could explain how this "octane select" worked ?!

Re: DB605AS info - need to determine WHERE and WHEN?
 

Somewhere I seem to recall a report indicating the "O" meant "bi-fuel" capability but in the context of powerboosting fuels and specifically "oxygen" (GM 1) and/or MW. Does that sound familar to anyone?

Hi guys:

In reference to codes...I pulled this from LWAG:

doa : Gothaer Waggonfabrik Aktiengeselschaft, Gotha

mcu : Erla Maschinen Werke G.m.b.H, Flugzeugbau, Leipzig N 24, Wer 1, Heiterblick 17 d

hsg : Dieck, W., Werk 1, Apparatebauanstalt, Aussig-Türmitz/Sud.

hsq : Daimler-Benz Motoren G.m.b.H, Genshagen Kreis Teltov

jlt : Rautenbach, Rudolf, Leichtmetallguss, Solingen



So it sounds like there is an hsg and hsq
