The Renault 6P, also called the Renault Bengali, was a series of air-cooled 6-cylinder inverted in-line aero engines designed and built in France from the late 1920s, which produced from NaNkWNaNkW to NaNkWNaNkW.
Charles Lindbergh's Atlantic Ocean crossing in 1927 inspired Renault to enter the light aero-engine market to diversify the range of engines they offered. To complement the 4P four-cylinder engines, Renault developed the 6P series, with NaN115 bore and NaN140 stroke; by adding two cylinders of the same bore and stroke.
Developed by Charles-Edmond Serre, the 9.5abbr=onNaNabbr=on 6P evolved to give NaN180, using NaN120 bore steel cylinder liners, aluminium alloy cylinder heads attached by long studs to the crankcase, Duralumin connecting rods and magnesium alloy crankcase.
The 6P was also produced in the USSR, as the MV-6, (MV - Motor Vozdushniy / Motor Voronezhskiy - air-cooled engine / Voronezh built engine).
