Ford Kent Engine - Zetec RoCam

Zetec RoCam

In 2000, Ford of Brazil developed a cheaper version of the Zetec-SE engine, to compete with the classic Volkswagen EA827 engine series also known as AP (from "Alta Performance", or "High Performance", in English) engine in Brazil. It is 8v SOHC instead of 16v DOHC and its body is made of 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it to be installed on the Ford Ka, replacing the Endura-E engine which by that time was considered underpowered and outdated.

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

In 2002 a supercharged 1.0 litre (94 hp; 95 PS) version was released for the Ford Fiesta, to compete with the 1.0 Turbo 16v (111 hp; 112 PS) version of the VW Gol.

In 2003 the Zetec RoCam engine was introduced in Europe, but labeled as Duratec 8v, for the SportKa, StreetKa and Fiesta. Later a 1.3 litre 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 "1.6L Flex", capable of running on both petrol and ethanol, even mixed at any proportion. This version also featured a high compression ratio (11.8:1) and "Compound High Turbulence" chambers, as used on the CHT engine.

Currently, this engine powers nearly all Brazilian Ford models – except those with 2.0 litre engines – in many different variants:

• 68/72 hp 1.3L Flex (Ford Ka)
• 101/106 hp 1.6L Flex (Ford Ka)
• 65/68 hp 1.0L Flex (Ford Fiesta)
• 105/111 hp 1.6L Flex (Ford Fiesta/ Fiesta Sedan), (Ford Focus), Ford EcoSport)
