Ford Zetec engine
The name was used by Ford Zetec for various in-line four -cylinder engine series with 1.0 to 2.4 liters and different performance levels. In addition, in various countries wearing a trim line of Ford vehicles have the same name.
Also, two of Cosworth commissioned by Ford developed 3.5-liter V8 and 3.0 - liter V10 engine in Formula 1 have been named Zetec, although these engines were completely own developments. With such a motor, Michael Schumacher won in 1994 Benetton B194 in his first world title.

Name
The late 1980s, different cylinder head concepts have been developed in the Ford engine development, designated by Greek letters. The type Zeta finally prevailed for series production. However, since the part of the Italian car manufacturer Lancia a lawsuit was to be expected ( Lancia built a car named Zeta and held the naming rights ), the engine Zetec in a word created from Zeta and Technology was renamed.
The name should also emphasize the technical standards with 16 valves and dual overhead camshafts. Starting in 2002, Ford began marketing reasons so gradually, to designate all Duratec petrol engines. With the introduction of the second series of the Focus in 2004, the name disappeared as Zetec engine designation. The equipment lines such as Zetec or Zetec -S are still used in some markets.
The term Zetec used by Ford for three different types of gasoline engines. This can easily lead to confusion, since many of these engines have nothing in common.
Motor types
The name Zetec was used for the following engines:
Zeta - family
In 1992, the new Zetec DOHC 16V engine was introduced. The engine should replace some of the CVH and the OHC / DOHC engines. The engine block was still based roughly on the CVH, the cylinder head was a completely new development. The engine has 16 valves, two overhead camshafts, hydraulic tappets, a one-piece light-alloy cylinder head, a cast iron engine block and an aluminum oil pan. The camshafts are driven via a toothed belt, the alternator, water and power steering pump on a flat -ribbed belts.
Initially, the motor with 1.6 and 1.8 liter engine in the Escort and Fiesta models were offered, with presentation of the new Mondeo 1993, the engine was also available with 2 liters capacity.
In 1995 there were minor technical revisions, as of this date is called the Zetec -E engine.
With the introduction of the new Focus 1998, there were far-reaching changes to the engine. Engine block and oil pan have been revised in order to minimize noise and vibration. It mechanical valve lifters were reinstated with shims, the connecting rods were lengthened, in turn flatter pistons were used.
This engine was also used in the Focus RS, the 2- liter engine with turbocharging made 158 kW ( 215 hp ), the name on the valve cover was already Duratec RS.
For the Focus ST170 Cosworth revised the cylinder head of the 2.0 and upgraded the engine in addition to an intake camshaft adjustment, a tubular manifold and a manifold from. With minor changes to the engine block of the labeled Duratec ST Zetec -R made 127 kW ( 173 hp).
The individual motor types are relatively easy to distinguish on the valve cover. The first Zetec have a silver lid with the bottom left attached label " DOHC16V ", the Zetec -E there carries the designation " ZETEC16V ". The Zetec -R has a black plastic cover and is therefore referred to, especially in Great Britain colloquially as " Blacktop ".
The engine was interesting during the construction period and for some manufacturers of kit cars and small volume manufacturers who used the engine in their vehicles. Thus, the Zetec inter alia Donkervoort D8 was used.
The Zeta engine family was built from 1991 to the end of 2004. It was largely replaced by the Mazda MZR based on the Duratec -HE, the smaller capacity classes were replaced by the Zetec -SE.
Sigma - family
The Zetec -SE (also labeled Zetec -S to find) was developed in collaboration with Yamaha. The engine design is fundamentally different from the Zeta family. A and outlet are reversed compared to the Zeta, engine block and cylinder head are made of light metal. Otherwise it is also about a 16-valve engine with two overhead camshafts driven by a toothed belt. The engine was first introduced in 1996 with the introduction of the new Ford Fiesta and was available with 1.25 and 1.4 liters of displacement. It was the first Ford engine was equipped with an intake duct of plastic. With introduction of the Ford Puma, the engine range of 1.6 and 1.7 liters of displacement was expanded. The 1.7 -liter version was built exclusively at Puma, made 92 kW (125 PS), had a revised intake system made of light metal and an intake camshaft adjustment.
An electrically controlled, hydraulic controlled variably adjusting the adjustment of the intake camshaft and thus achieved a high torque output over the entire rpm range. Furthermore, it was working with an internal exhaust gas recirculation, so that could be dispensed with an external EGR system. Also new was the arrangement of the Tappet. To keep the accelerated mass of the valve train as low as possible, they were located below the tappets and could thus be smaller.
The engines were also in the Ford Focus, Ford Fusion and offered in the Mazda 121.
From 2002, the engines were labeled with Duratec and were the basis for the new turbocharged EcoBoost engine Ford from 2004, the 1.6-liter version of the first Ford engine with two independently adjustable camshaft (Ti- VCT Twin independent variable camshaft timing) equipped.
The 1.6-liter Ti-VCT engine is also offered as flexi-fuel variant in the Focus Factory. This engine can be operated with standard gasoline and ethanol fuel (E85 ). The motor and the motor controller are specially designed to run on ethanol, any mixing ratio between gasoline and ethanol is possible. It is only used, a fuel tank, the mixing ratio is determined by sensors. This engine replaces the 1.8 - liter Duratec FFV. The 2.0 - liter Duratec FFV is offered for Mondeo, S -Max and Galaxy.
The engine was also often used in racing, as in the Ford Puma Cup, the Ford Fiesta ST Cup, in various Formula series as Super 1600 engine and amateur sport.

Zetec Rocam
Ford Brazil developed in 2000 a cheaper version of the Zetec -S. These were an engine with 8 valves and an overhead, driven by a timing chain camshaft. The cylinder head was made of light metal, the engine block is made of cast iron. This engine ran much rougher and louder than the Zetec - S, but had a higher torque. This is achieved inter alia through Rocam ( roller finger camshaft). The design of the engine block is based on the old Kent OHV engine, the cylinder head design reminiscent of the CVH.
In South America, the engine is offered today in different versions with 1.0 to 1.6 liters. In 2002, the engine was introduced in Europe with a capacity of 1.3 liters and designated Duratec 8V. He was available at the Ka and the Fiesta '02. Later, a 1.6-liter variant for the SportKa and the Streetka was available. With the expiry of the model generations in 2008 ended the sale of these engines in Europe. The production of the European versions of the engine was held in South Africa.
Zetec as a trim
Since 1998 in the UK the name Zetec well as a trim level, there he replaced the variant Si. Zetec usually referred to the sportier variants, but also a Zetec engine is not mandatory in these vehicles fitted. So driven vehicle be offered as a Zetec with a diesel engine. After the end of the name Zetec engine designation as the trim level of Ford is still used in the UK.
Using ( Europe)
As an all-wheel: 97 kW/132 hp with modified air intake, only in A and CH as Mondeo RS Limited edition Ford Racing Puma, only in the UK
Some motors of the Sigma series will continue to be marketed by Ford as the Duratec.
Zetec S 3 DISI
2001 at the IAA in Frankfurt Zetec S 3 DISI (Direct Injection Spark Ignition, translated: Direct with electric ignition ) presented called motor prototype to the public. It was a three-cylinder gasoline engine with 1.1 liter displacement, which should afford means of turbocharging and direct fuel injection 81 kW (110 hp). The fuel consumption should be 15 to 30 percent less than that of the 1.8-liter engine of similar performance. A launch of this engine, however, never took place because the calculated engine and transmission surcharge of DM 4500 (~ € 2300 ) were not considered marketable. Since 2012, the new EcoBoost engine with 1.0 liter displacement is available. The three- cylinder engine produces with turbocharging and direct injection 74 kW ( 100 hp ) or 92 kW ( 125 hp). At 4.8 liters per 100 km consumption in the Ford Focus he is so far the most economical gasoline engine in the compact class.
Motorsport engines
Under the name Zetec -R also different eight-and ten -cylinder engines of various teams were used in Formula 1 between 1994 and 2001. In these engines, it was pure motorsport engines that have been developed from scratch by Cosworth. They were not technically related to the Zetec engine family.
Eight-cylinder engines
The Zetec -R eight-cylinder engines have been used by the following teams:
Ten-cylinder engines
The Zetec -R ten-cylinder engines have been used by the following teams:
