Editing Ford Sigma engine (section)

==Zetec RoCam==
In 2000, [[Ford Motor Company|Ford]] of [[Brazil]] developed a cheaper version of the Zetec-SE engine, to compete with the classic [[Volkswagen EA827 engine]] series known locally as {{ill|Volkswagen AP|pt}} (from ''Alta Performance'', "High Performance" in English) engine in Brazil. It is 8v [[SOHC]] instead of 16v [[DOHC]] and its block is made of cast iron instead of aluminum. Also, its camshaft is driven by a chain instead of a belt. 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 (Rollifinger Camshaft) feature. It's also a much smaller engine than the SE version, which allowed it to be installed on the [[Ford Ka]], replacing the [[Ford Kent engine#Endura-E (1995–2002)|Endura-E]] engine which by that time was considered underpowered and outdated.

The engine also featured a new patented process for the aluminum [[Cylinder head|head]] production, which resulted in a better alloy than those produced in Spain and UK, and at a lower production cost.

In 2002 a [[Supercharger|supercharged]] 1.0-litre {{cvt|95|PS|kW hp|0}} version was released for the [[Ford Fiesta]], to compete with the 1.0 Turbo 16v {{cvt|112|PS|kW hp|0}} version of the [[Volkswagen Gol]].

In 2001 the Zetec RoCam engine was introduced in Europe, but labeled as [[Ford Duratec engine#Duratec 8v|Duratec 8v]], for the Ka and Fiesta. Later a 1.6-litre version was also released for the SportKa and StreetKa. The European versions of the engine are produced in the South Africa plant.

In October/2004 a newer [[bi-fuel engine|bi-fuel]] version was introduced labeled "1.6&nbsp;L Flex", capable of running on both petrol and [[Ethanol fuel|ethanol]], even mixed at any proportion. This version also featured a high compression ratio of 12.3:1 and "Compound High Turbulence" chambers, as used on the [[Ford CHT engine|CHT engine]]. The 1.0&nbsp;L Flex runs with a compression of 12.8:1.

Currently, this engine powers nearly all Brazilian [[Ford Motor Company|Ford]] models – except those with 2.0 litre engines – in many different variants:
* 101/106&nbsp;hp 1.6&nbsp;L Flex ([[Ford Ka]])
* 71/73&nbsp;hp 1.0&nbsp;L Flex ([[Ford Fiesta]]), 69/73&nbsp;hp 1.0&nbsp;L Flex after 2012 in Brazil
* 105/111&nbsp;hp 1.6&nbsp;L Flex ([[Ford Fiesta]]/ Fiesta Sedan), ([[Ford Focus (International)|Ford Focus]]), [[Ford EcoSport]])
