The Ventoux engine, also known as the Billancourt engine, was an automotive engine designed by Renault for the Renault 4CV, used subsequently until 1997, and named after Mont Ventoux in Provence. It later received the internal code "B", for Billancourt, where the casting took place.[1]

History
The engine is liquid-cooled, with four cylinders in line. It is also characterised by its three main bearing design and its piston stroke of 80 mm. It has a cast-iron block, aluminum cylinder head and uses a lateral camshaft to operate overhead valves, which also operated the fan belt on its other end. Renault replaced this engine with the Cléon-Fonte engine completely new design.
This engine designed by Fernand Picard engineer was produced from 1947 to 1985, in displacements of 603 cc, 748 cc, 782 cc, and 845 cc, the differences being effected by changing the cylinder bore diameter.

Brazil
The following Willys-Overland models used the Ventoux engine:
- Interlagos, 845cc, 40/53HP, 904cc, 56HP and 1000cc, 70HP

- Gordini, 845cc 40HP

The following Brazilian Ford models used an substitute/evolution of the Ventoux engine, basically the same as used in the Renault 8/12 (Sierra/Cléon engine and CHT engine):
- Corcel I and Belina I, 1289cc, 68 and 80HP; 1372cc, 75 and 85HP
- Corcel II, Belina II, 1372cc, 72CV and 76CV; 1555cc, 90CV;
- Ford Del Rey and Scala, 1555cc, 90CV
- Ford Escort MK III,1340CC, 62CV 1555cc, 76CV and 1555cc, 86CV (XR3)
The following Brazilian VW models also used CHT engine (in joint-venture Autolatina):
Willys-Overland do Brasil produced this engine in Brazil for use in the Interlagos (Renault Alpine) and Dauphine, which they built under Renault license from 1959 to 1967.
Ford do Brasil acquired Willys-Overland do Brasil in 1968 and evolved its design into a new engine with a higher displacement (of 1,300 cc and 1,400 cc), which had a different block, used five main crankshaft bearings (instead of the Ventoux' three). After that Ford continued to produce this engine in two displacements, 1,400 cc and 1,600 cc, with the last one being offered in both gasoline and ethanol versions. In 1984 Ford made several enhancements to improve the engine performance, mainly in the cylinder head and crankshaft, and rebranded it as the "CHT engine" (Compound High Turbulence).[2][3] It carved its own fame in Brazil, to the point that many nowadays also refer erroneously to the earlier Ventoux engines as "CHT"s.
