Welk motortype is dit op de foto's? Sommige kennissen zeiden dat het een DB 603 is. Maar waar kan ik het definitieve antwoord vinden?

Hoi Pieter, ik denk dat je de vertaling hebt aanstaan in de browser. Kun je me een pm sturen (envelopje binnen in het menu) misschien dat we samen dat kunnen fixen? Ondertussen zal ik je berichten even vertalen.

Hi,
It is difficult to say precisely which DB601, DB603 or DB605 that it is from this shot. However, you have the two pistons at the middle in the picture that look perfectly placed to accurately measure the diameters across the top edges. Please measure the accurately the diameter of the pistons inside the steel liners in millimetres for me. Also the main bearing caps underneath should show figures, especially some numbers cast into them. Please photo them as much as possible and I can help.

Cheers

So, what is going on here? It is pretty easy to write, translate and post! Also easy to translate posted replies.
Pieter, do you really want professional quality info about this relic?

Hi,
For anyone interested, I am at the moment suspecting that this is a DB 601A/N relic. However, further photo's and information from Pieter is needed for full identification.

Cheers

Hello Marcel Thank you for your help and advice with Google Chrome. It's good now. Best regards Pieter Hoekstra

It was kinda' fun trying to translate it phonetically.

During the restoration I photographed the motor a few times, i"ll send them and after that new photo's.

Best regards Pieter

Hi Pieter,

Thank you, for the extra pictures. I can identify this engine as a DB 601 A. There are some more specifics that I shall describe later. You did not include a detail of the piston head diameters on those fully exposed piston tops, please could you do that for full definition?
I will post again with the details later today.

Cheers

Hi,
As you can see in the extra photo's, this crankshaft and piston relic is from a large V12 engine that has crashed and appears to have been in sea water. The great majority of the engines' original aluminium casings have been corroded away, but much of the steel and anodised components have survived. The relic looks to have suffered a combination of crash damage and some subsequent/recovery damages, although the breakage of the crankshaft and loss of the components including the front-end main bearing Number 1 and the pinion bearing would appear to be due to the original impact. The crankshaft and rotating components from a point at the rear of the front No 1 main bearing survive, including most pistons, rods, main bearings and the starter drive dog at the very rear.
Details of the components conclusively show that this was an early DB 601 engine. Importantly, the crankcase cross-bracing tie-bars pass through the upper arches of the main bearing caps, which is distinctive of the DB 601A-B, N-P.
The internal double locknuts on the tie-bars Nr3 and 4 are specific to the DB 601 A-B, N-P.
The piston crowns appear to be the slightly concave DB 601 A-B type. The piston diameter has not been fully shown but should measure 149.5mm at the top edge on undamaged standard pistons.
The part numbers have not all been fully exposed or clearly photographed, however main bearing caps 2, 3 and 6 show enough detail for the engine serial number 1162? to be seen.
This would likely be engine 11620 to 11629, which would have been a DB Berlin Marienfelde built engine, from 1939.
The engine would likely have been fitted to an early Bf 109, Bf 110 or a He 111P. Other relics from the same crash might confirm the type of aircraft.

Impressive.

Impressive.

Hi,
Thanks. The details are all there, it just takes a lot of specific background information to interpret.
Unfortunately, illustrating all the detail here is very time consuming, but I have described what I can see in the given photo's.
