DB 601 N


    
        The DB 601N was an improved version of the DB 601 that with it's re-designed cylinder heads, increased manifold pressure and revolutions, using 'C-2' natural or 'C-3' synthetic 100 octane fuel obtained increased power output. Originally 1400 PS output was planned. The powerplant entered production in the end of 1939 and was
used in the Bf 109E-4/N, E-7/N and Bf 110C fighters and destroyer, and the He 111 P and Do 215 bombers. The datasheet notes that the Bf 109F use another version of the DB 601N, with improved supercharger ('verbessertem Lader'). This latter version had higher rated altitude, otherwise it was similiar.
It should be noted that German datasheets are sometimes quite inconsistent about time limitations; this one qoute 1-min limitation, possibly carried over in error from the DB 601A's 1-min special power boost. Other documents of the DB 601N however give the limit as 5 minutes.

       
On the
Generalluftzeugmeister meeting on 19 July 1940 at the it was noted that up to that date one Gruppe (Wing, each with 3 Staffeln, or Squadrons with 12 planes) of Bf 109 had re-equiped with DB 601N. 1

Horst Perez on, when it was shot down on the 30th September 1940 over East Dean during the Battle of Britain. Note the fuel triangle with the '100' label, pointo to 100 octane fuel and the DB 601N.
