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 {{convert|abbr=on|95|hp|kW}} to {{convert|abbr=on|150|hp|kW}}. Design and developmentCharles Lindbergh'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 {{convert|abbr=on|115|mm|in}} bore and {{convert|abbr=on|140|mm|in}} stroke, delivered {{convert|abbr=on|95|hp|kW}} 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 {{convert|abbr=on|110|hp|kW}} to {{convert|abbr=on|120|hp|kW}}, with the adoption of {{convert|abbr=on|120|mm|in}} 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 MV-4 (Motor Vozdushniy / Motor Voronezhskiy - air-cooled engine / Voronezh built engine {correct interpretation is unclear}). In 1946 production of the Renault 4P-01 resumed at the SNECMA factory at Arnage, until 1949, with at least 762 engines manufactured. Variants
The initial version with {{convert|abbr=on|115|mm|in|2}} bore and {{convert|abbr=on|140|mm|in|2}} stroke, delivered {{convert|abbr=on|95|hp|kW|disp=flip}}
upright {{convert|95|hp|abbr=on|disp=flip}} / {{convert|135|lb|abbr=on|disp=flip}} - Caudron Luciole
Inverted development of the Pb retaining the {{convert|abbr=on|115|mm|in|2}} bore
Further development of the Ps retaining the {{convert|abbr=on|115|mm|in|2}} bore
inverted 4Pc
Inverted, introduced {{convert|abbr=on|120|mm|in|2}} bore steel cylinder liners, aluminium alloy cylinder heads attached by long studs to the crankcase, Duralumin connecting rods and magnesium alloy crankcase. 110 hp / 150 kg - Hanriot 16, 120 hp / 155 kg - Caudron Phalène
Inverted, rated at {{convert|abbr=on|150|hp|kW|disp=flip}} for take-off, the 4Pei entered production before WWII[1]
Inverted lower rated version, giving {{convert|abbr=on|105|hp|kW|disp=flip}} for take-off, using 73-octane fuel.[1]
{{convert|abbr=on|140|hp|kW|disp=flip}} with fuel injection.
Postwar production version of the 4Pei, rated at {{convert|abbr=on|145|hp|kW}} for take-off.[2]
As the 4P-01 but with an inverted flight Zenith carburettor[2]
As for the 4P-03 but with a modified oil system[2]
