DB engine?

[Pieter Hoekstra Urk]

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.

Whow many thanks i sm very grateful for this answer.
I" ll search for better photo' s off numbers on the engine.

Many thanks

Hi Pieter,

Thanks for the extra photo's. The picture of the piston shows a diameter of 149/150mm approx and this matches the DB 601. The last picture of the series above, also shows the rear of the crankshaft quite well, you can see the large spring-drive gear that drove the supercharger shaft, and the starter extension at the very rear.
I hope the information is helpful. It would be interesting to know anything about the crash or the general location?
