The Gnome-Rhône 14N was a 14-cylinder two-row air-cooled
radial engine
The radial engine is a reciprocating engine, reciprocating type internal combustion engine, internal combustion engine configuration in which the cylinder (engine), cylinders "radiate" outward from a central crankcase like the spokes of a wheel. ...

. A development of the
Gnome-Rhône 14K, the 14N was used on several French and even one German aircraft.
Design and development
The 14K's reliability was poor, so Gnome-Rhône carried out major redesign, using different materials for the pistons and valves, and enlarging the cooling fins to increase surface area by 39%.
The 14N was introduced in 1937 and was quickly installed on several aircraft models. In 1939, minor improvements allowed Gnome-Rhône to increase the compression ratio from 6.1:1 to 6.8:1, which increased power.
The 14N was further developed into the
Gnome-Rhône 14R
The SNECMA 14R was a 14-cylinder two-row air-cooled radial engine developed in France just prior to the start of World War II from the Gnome-Rhône 14N. The 14N radial engine was itself an improved version of the popular pre-war Gnome-Rhône 14K ...
