Zetec Rocam (duratec 8v)
In 2000, Ford of Brazil developed a cheaper version of the zetec-s engine. Single cam,8 valves driven by a chain. As a result, this engine exhibits rougher behaviour, producing more vibration and noise. On the other hand, it has a superb torque output thanks to the addition of the Rocam (rollerfinger camshaft) feature.
In 2003, the Zetec-Rocam engine was introduced in Europe, but labeled as Duratec 8v, for the SportKa and StreetKa models. Later a 1.3 L version was also released as an option for the standard model, but the European versions of the engine are produced in the South Africa plant.
In October/2004 a newer bi-fuel version was introduced labeled "1.6 L Flex", capable of running on both petrol and ethanol, even mixed at any proportion. This version also featured "Compound High Turbulence" chambers, as used on the CHT engine.
