- Summary
- The Societa Anonima Fiat of Turin, Italy was founded in 1898 by Giovanni Agnelli, and drew on its race car experience to manufacture its first aircraft engine in 1908. During World War I, Fiat produced over 15,000 aircraft engines, said to be more than all other Italian manufacturers combined. A total of 13,260 A-12 and A-12 bis engines were built between 1916 and 1919.
- The six-cylinder, in-line, water-cooled A-12 engine produced 149 kW (200 shp), with the A-12 bis being a later development. In general, the dimensions were identical, but the A-12 bis had a 4.75 compression ratio, higher than that usually employed in the earlier model. The principal changes were new carburetors and manifolds, and the substitution of an oil pressure feed to the camshaft housing.
- Among the aircraft powered by A-12 engines was the Societa Italiano Aviazione F.B. Biplane. This engine artifact has been modified for marine installation.
