The Cyclone engine is Ford Motor Company's latest DOHC V6 family of gasoline engines introduced in 2006.
The Cyclone engine succeeds Ford's previous V6 engine families, the Ford Essex engine introduced in 1981, the Ford Vulcan engine introduced in 1985, the Duratec V6 introduced in 1993, and the Ford Cologne V6 engine, whose original 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.
Notable Cyclone features include a capacity for displacements ranging up to 4.0 L, 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.
The Duratec 33 (3.3L) is a down sized version of Duratec 35 with direct injection starting in 2018 model year for Ford F-150, serving as the new base engine.
The Duratec 35 displaces 3.5 L (3496 cc, 213 CID) with a 92.5 mm (3.64 in) bore and 86.7 mm (3.41 in) stroke. Due to packaging differences (primarily the relocation of the water pump to the valley behind the timing cover and driven by the timing chain. Replacing the water pump is an approximate $1800.00 USD repair. This may also require the removal of the engine to replace the timing chain if any of the internal plastic guides are damaged. That will require even higher cost of repair.), the 3.5 L engine will fit into any engine bay the smaller Duratec 3.0 L will, and replaced it in some applications (notably the Ford Taurus) in the 2008 model year. Production began in 2006 for the Ford Edge, Lincoln MKX, and Lincoln MKZ.
