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.
Development
[edit | edit source]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.
