Fiat A.12


  Fiat-A12

 

The Fiat A.12 was a six-cylinder liquid-cooled in-line engine 160 mm x 180 mm, 21.71 liters, 245–300 hp at 1,700 rpm. The A.12 was a rather large aero engine at the time and its dimensions were more typical of a marine engine, but it was efficient and reliable. No doubt Fiat's experience with large racing engines contributed to its success. A total of 13,260 A.12s were produced between 1916 and 1919.
