Piaggio P.XIX

The Piaggio P.XIX was an Italian aircraft engine produced by Rinaldo Piaggio S.p.A. during World War II and used to power aircraft of the Regia Aeronautica.

The engine was part of a line of 14-cylinder radial engines developed from Piaggio based on the Gnome-Rhône Mistral Major, which was itself loosely based on the Bristol Jupiter.^[1] It was derived from the earlier P.XI but with a higher compression ratio.
