The Renault 4P, also called the Renault Bengali Junior, was a series of air-cooled 4-cylinder inverted in-line aero engines designed and built in France from 1927, which produced from to.

Design and development

's Atlantic Ocean crossing in 1927 inspired Renault to enter the light aero-engine market to diversify the range of engines they offered. The resulting Renault 4Ps, with bore and stroke, delivered and proved popular, later versions powering several record-breaking light aircraft.
Developed by Charles-Edmond Serre, by 1931 the 6.3-litre 4Pdi had evolved to give to, with the adoption of bore steel cylinder liners, aluminium alloy cylinder heads attached by long studs to the crankcase, Duralumin connecting rods and magnesium alloy crankcase.
The 4Pei was produced in the USSR, with local equipment and features from the MV-6, as the Voronezh MV-4.
In 1946 production of the Renault 4P-01 resumed at the SNECMA factory at Arnage, until 1949, with at least 762 engines manufactured.
