| Predecessor | Ford Duratec V6 |
The Cyclone engine, also branded Duratec, is Ford Motor Company's latest DOHC family of gasoline V6 engines introduced in 2006.[1] The Cyclone succeeds Ford's previous V6 engine families, including the Canadian built Ford Essex engine introduced in 1981, the Ford Vulcan engine introduced in 1985, the original Duratec V6 introduced in 1993, and the Ford Cologne V6 engine, whose design dates back to 1962. The first version of the Cyclone engine, a 3.5 L V6, appeared in the 2007 Ford Edge and the Lincoln-badged luxury variant, the Lincoln MKX, as well as the Lincoln MKZ. Mazda badges its versions of the Cyclone MZI as it did with its versions of the Duratec V6.
Although Ford continues using the Duratec name, the Cyclone shares no components or design with the previous Duratec and was entirely new.[2]
Notable Cyclone features include a capacity for displacements ranging up to 4.0 L,[1] DOHC 4-valve per cylinder heads, direct acting mechanical bucket (DAMB) camshaft tappets, variable cam timing (iVCT) on the intake camshafts, and twin-independent variable cam timing (Ti-VCT) on some later versions. Features such as Gasoline direct injection and turbocharging were considerations in the design phase and have been added to the engine as part of EcoBoost. The 3.5 L is ULEV-II compliant and is capable of meeting the PZEV requirement.
