To all engine specialists at this forum: From which engine is that part from? Any idea about the meaning of the numbers? I appreciate any information because I want to identify that aircraft. Thanks - Kurtl

It looks like a Daimler-Benz engine. The nuts on the big end of the conectionrod has no castlenuts. The liner has a thread on the lower end. The part with the long scews the rest of the crankcase.
 
There are no hex head srews and nuts at all. Everything looks knurled. - Kurtl
 
The Rod end cap is very similar to a DB 601. Here are some pics comparing them.

Hey, that really looks the same. Do you have any construction drawings of a DB 601? Or any link on the web available?

I found some 3cm an 13mm shells at the same crashplace today. So that underlines that it must be german. What do you think?

Kurtl
 
I agree - I don't have much on the 601, I found that cut away on the Internet. I did read somewhere that the rod cap bolt heads were installed with a special tool, that's why I asked about that in my first post. I was surprised to see the similarities. I'd keep searching the site, maybe you'll find some airframe parts.

Your posts are always fascinating! :thumbright:

The size of the shells and the in-line engine tells me it's a late-model Me 109, probably a G or K, which means it's a DB 605 engine, not a 601.

This is the best I could find and I think you can order the blue prints from them. Dont know if this will help at all though.

DB 601

Daimler Benz DB-601 | Aircraft Blueprint | Aviation History | Airplane Plans

And the only site that I could find that had a really nice DB 605 construnction drawings was down.
 
Kurtl where in Austria ? we may be able to pinpoint a LW unit here .

great piece of history you have with well preserved markings. Last thing here that 3cm round, just the shell correct and if you have part of the round ooooooooooooooooh would I be careful with that, probably an HE-Minengeschoss and even after all these years if that went off you would have a definate huge hole in the area

I would have to check but the Sturmgruppe of JG 3 went after some US 15th AF heavies on August 3, 1944 and several crashed due to return fire of the bombers, you may just have a couple of parts from an Fw 190A-8/R2, but am not sure again of where you found this marvelous item.

Just noticed something . . . it would appear the crankshaft, connecting rod piston are made out of steel due to the amount of corrosion, whereas the journal bearing cap appears to be made out of some sort of alloy (perhaps magnesium?) due to the lack of corrosion. This might help the engine detectives . ..
 
This may help to identify The Parts of the Engine:
1: upperhalf of the bearing support
2:cylinder barrel
3: piston pin
4: articulated rod
5: master rod
6: crankshaft

so gentlemen are we then agreeing that this is from the engine of a Bf 109 then and not an Fw 190A ?

thanks Dolpho for the markings in numerations of the piston and it's crank compared to the posted DB engine a great comparison

In item two, where are the piston ring serrations?
 
Thanks for paying so much interest in my topic. You are all a great help!

I do believe that the piston is part of a DB engine. So I guess it is a Bf 109 G-6/U4. (U4 because of the 3 cm) The location could fit to Uffz. Hanz Kemmerling, of 2. Staffel JG302, Bf109 G-6 "Red 6", WNr. 441 795. But that is only a first suspect. Could also be JG27 or JG 300. Unfortunately I do not have a date when it crashed.
The only color parts I could find were light grey and some had light blue on them.

@ Erich: If have lot of respect about amunition. Especially about german 3 cm because I do not know how they work. Last time I visited this crashplace I noticed at least three 3 cm bullets. One was cut open almost the whole way so I looked at it closer. It was empty at all. At home I could identify it as 3 cm Minengeschoss Leuchtspur mit Zerleger (http://www.xs4all.nl/~robdebie/me163/weapons15.htm). On the outside there were fragments of yellow color. The head was missing. The other two were headless too but they seemed to be still full with HA41. Could they still explode?

On other tiny parts I found stampings. Two are round with "Erla 54", and "Erla 22". There was a tube with "NW 25" and something else on it I could not identify. And an angular stamping "BA 9409".

I hope that the 3 cm are not dangerous anymore.

Kurtl I would not have any of the fine filment contents anywhere near you, yes I have heard of major accidents in Europe when 2cm and 3cm were unearthed.

let me do some more research on JG 302 and I think we talked about this the two of us several months ago correct ?

Hello Flyboy, you can´t see the piston ( 7 ) . The foto show thr cylinderbarrel. The thread at the bottomend is for fixing the cylinderbank with a special nut (8). You will see it only on DB engines. Sorry i have no scanner for a better picture.
The numbers are the same from yesterday.

Ok - but look at the original photo and the cut away of the 601. I circled the areas I'm talking about. There are no serration for the piston rings and no oil passages visible on the article piston.
