The Vedeneyev M14P is a nine cylinder radial, four-stroke, air cooled petrol engine. The induction system uses a gear driven supercharger and a carburettor of automatic mixture type. Power is transmitted to the propeller via a reduction gearbox. Its design dates from the 1930s.

The engine has a speed governor, carburettor, two magnetos, mechanical fuel pump, generator and oil pump. The engine remains fully operational during inverted flight. The engine is pneumatically started.

The engine is left turning (counter-clockwise) when viewed from the cockpit. This is opposite rotation to most western aero-engines.

In recent times, the M-14P has become increasingly popular in experimental aircraft designs such as the Murphy Moose and others.
