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

The Zeta shared some parts with other Ford engines developed at the time, including the smaller Sigma I4 and larger Duratec V6. The 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. It is a commonly held myth that the Zeta is merely a DOHC 16-valve development of the CVH, but whilst the cylinder blocks have similarities - this is largely to do with the need to attach the engine to legacy transmissions and mounting points on existing models and also the Zeta was also made in the same factory on the same production tooling; the blocks are not actually interchangeable.

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, BC5/iB5, G5M/G25MR, CD4E and MTX-75 gearboxes using the same bell bolt pattern as the Crossflow.

2.0 The 2.0 L Zetec shared its bore and 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. The SVT variant was equipped with Variable Valve Timing on the Intake Cam.

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.
