Ju-213A and 100/130 Grade Fuel

[krieghund]

What kind of power do you get if you put a proper grade of fuel thru a Junkers Ju-213A?

This is from"Aircraft Engines of the World 1949" by Paul Wilkinson



Still in production by the french at this time

The answer is: the same. Higher grade fuel alone doesn't yield higher power outputs, but it allows for higher manifold pressure or compression ratio, which increase output; only if these latter are increase (and the engine can stand the increased load mechanically) will power increase. But its a very interesting find, did the French produce the 213 post war, too? I did not know!

IIRC the Jumo 213A had two versions, one with lower and one with higher compression ratio, for low grade B-4 and high grade C-3 respectively.
