Oddball engines and prototypes

[Niels Abildgaard]

Any idea what engine is it and specs ~1940 production, used by German military.
Scavenging through piston

Attachment 346566

It looks like a drone engine and the scavenge system was named something like Schlika and had been used in motorbikes before WW2.

Like Niels wrote, it seems to be a boxer with Schliha (spelling!) scavenging through the piston. And the shielded spark plug caps suggest aviation use.
I wonder about the drone application though. Drones were mainly used for target shooting practice, but back then the German Wehrmacht and Luftwaffe had no shortage of real targets.

It reminds me of a RGP warhead.
or i guess in this case a Panzerfaust

Wiki says 20 horsepower 1200ccm and made for an aircraft called erla6

https://de.wikipedia.org/wiki/Erla_6

Erla6 was a intermidiate trainer between gliders and real aircrafts for Luftwaffe pilots to be.

Thanks ALL !!! You are always have answers on any 2-stroke questions
Guys who have this engine strongly believe it is 45hp and trying to find investor to reborn.
Me sceptical to this idea

How did a german prototype aircraft engine from the late thities suvive 80 years in Russia?
There is a very interesting story I think.
I will love to read it.

I'm told that the Ford (Model A) engines survived in a Soviet "Jeep" till after WW2. (however I can't confirm that - just something I remember reading).
The Russians were often able make good use of things the Americans didn't persevere with! (like the mid engined Bell Airacobra aircraft which they used with great success as a ground attack aircraft).

It is still difficult to imagine, how something could have been created during Stalin's terror. From the 1930s to the 1950s, the vast majority of the Russian and Ukrainian intelligent mind was either killed or imprisoned. Before and after the war, the most needed and “dangerous” minds were locked up in Sharashka ( https://en.wikipedia.org/wiki/Sharashka
https://en.wikipedia.org/wiki/Gorodomlya_Island) Sergei Pavlovich Korolev together with Helmut Gröttrup.
Stalin wanted copy everything, to the smallest detail, even, a random hole in the body of example bomber Boeing B-29 was copied to TU-4.
In Soviet times, say in Lithuania, every factory was working for military and all this was hidden under a wide variety of productions for civilians. Remember, the tape recorder factory in Vilnius, that main production actually was recording equipment (with recording wire) for submarines.

After the war, most of the DKW factory was transferred to the Soviet land and the DKW reborn in two-stroke racing motorcycles as ГК-1, С1Б, С2Б, С3В. They were developed until FIM banned supercharging.

Add pic with similar type to Schliha, just reversed.

It starts to get very interesting.
The pictures from JBIPLANE were judged to be of Schliha type by me and at least another have seen it all .
We were wrong methinks..
They look more as the russian devellopment according to Katinas second but last picture.
Exhaust is not controlled by main piston but by the piston- extension to top of head and overboard.
The second picture from my colleaque in having seen everything and Katinas last pictures show Schliha where exhaust leaves mid cylinder.
The aeroplane picture with the true Schliha engine is from ca 1937 Germany.
Both the Schliha and the russian devellopment would have been simpler and better with normal valves in top.
I think
Spending time here , enjoy some numbers.

Niels, last picture in previous post, is Erla6 plane with true Schliha engine. As plane was more oriented for peace time, there is no interest in them from Germany militarists before war.

The guy who own it says he take it in watersport section in Samara city ~20 years ago. They reworked such engines to water cooling.

A russian pendant to McCullogh drone engines?

https://www.wingsofhistory.org/mcculloch-40-hp/

Would be interesting to compare fuel efficiency numbers.

In Soviet union for drones produced 38hp 12.6 kg (without reducer) engines


Used on crafts like tuis


Tomorrow leave on holydays. Probavly will out of internet couple of weeks or so.

Hollidays are not so important as history of this strange,old reverse Schliha aircraft engine that later was modified for water cooling.
OK enjoy your holliday but do not forget us for wine ,sunshine and women.

[breezy]

would this be considered an opposed piston engine?
