German avia motors question
 

Hallo gents!

Some sourses say, that german twin-engined a/c ahd its own versions of engines. For example, they claim that Bf110E-2 had DB601P instead of DB601N. But it is strange for me, as I see sign "N" on those aircraft motor cowlings, and DB601N in original documents.

That sourse claim, that special engines for twin-engined a/c's had its own prop/engine ratio). Is it true?

I always thought, that following is correct:

As far as I know the letter on the engine cowlings (at least for the Bf110) indicates the fuel and not the engine type. A stands for 87 octane B-3 fuel and N for 100 octane C2 or C3 fuel.

Evgeny,
The "N" on Bf 109E and 110E cowlings was intended as a recognition aid for ground refueling services. It quickly informed the ground crew which aircraft had the DB 601N engine...and by extention...its corresponding special fuel requirement of C2 or C3.

Thanks gents!

Sorry, but I will be more concrete: what engine was installed on Bf110E-1/N or Bf110E-2/N - DB601N or DB601P?

Evgeny,
According to Mtt's documents, all subtypes of the Bf 110 E-series (E-1, E-2 and E-3) were equipped with the DB 601N as standard equipment. There is no mention of any other engine for this series. Interestingly, at least one document lists the E-1 as the "Bf 110 E-1/N" even though the "N" was not necessary. Further, all Bf 110 series from the C-1 series up to, and including, the Bf 110 D-4 each had the DB 601A as standard.

DB did build a 601P.
