Developed in the late 1980s by the Ford Motor Company, the Ford Zeta engine was a straight-4, double overhead cam internal combustion engine with which Ford had intended to replace the analogous Pinto and CVH models.

Ford designed the Zeta to share some parts with other Ford engine developments at the time, including the smaller Sigma I-4 and larger Duratec V6. This engine shares its bore and stroke dimensions with the 2-valve CVH engine. Ford Power Products sells the Zeta in 1.8 L and 2.0 L versions as the MVH.
Production of the engines, renamed Zetec (the rename occurred because Lancia owned the "Zeta" trademark), began at Ford's Bridgend plant in Wales in September 1991, with later production added at Cologne, Germany in 1992 and Chihuahua, Chihuahua, Mexico, in 1993. The first Zetecs displaced 1.8 L, with a 2.0 L version arriving quickly afterwards. The final Zeta Zetec was produced on December 10, 2004 at the Bridgend factory with over 3,500,000 built at that location.
The engine fits the Ford T9, B5/iB5, G5M/G25MR, CD4E and MTX-75 gearboxes using the same bell bolt pattern as the Crossflow.

2.0
editThe 2.0 L Zetec shared its 84.8 mm (3.339 in) bore and 88.0 mm (3.465 in) stroke with its predecessor, the 2.0 L 2-valve CVH. On top of the 16 Valve DOHC head, the Zetec for the US Market Escort ZX2, Contour, and Cougar gained Variable Valve Timing on the Exhaust Cam, removing its requirement of EGR for US Emissions.
A high 10.2:1 compression ratio and larger valves contributed to the SVT version's much-higher output; while a special ECU tune that modified the Variable Valve Timing, among other settings, contributed to the 10% power increase on the ZX2 S/R.
