Junkers Engines - Jumo 213
That's not true. Most Jumo213 engines were low octane models because high octate fuel was scarce in WWII Germany. But Junkers did produce the 2,031 hp Jumo211F in small numbers.
The 2,563 hp Jumo213J may have entered mass production during 1945 if not for the end of the war. That's a V-12 with serious power!
Was the RM17SM standard engine ever used in a service aircraft?
Isn't that rough on head gaskets, piston rings and piston crowns? Not to mention the supercharger and associated plumbing which must be capable of delivering that much air pressure and volume.
I have my doubts if that is true. C3 was considered to be just another type of fuel. Production was not much more complicated and there were no C3 shortages as far as I can tell.Junkers Engines - Jumo 213

What have we here???. Looks like a two stage supercharger casing, like a Jumo 213E/F but... Everything I have ever read indicated that the Jumo 213A, 213E, and 213F had three valves per cylinder, two intake valves and a single exhaust valve. But look at picture 224701. Clearly two exhaust valves per cylinder.. From what I have read the only Jumo 213 engine variant with four valves per cylinder was the 213J.
And what's up with the inch / cm yard stick laying alongside the crankcase between the lifting shackles?? If would seem that this series of images was taken post war at a Junkers facility by a British or American technical investigation group.
I also have a question - is that engine still somewhere preserved?
