Ford Cyclone Engine

Ford Cyclone Engine

The Cyclone engine is Ford Motor Company's latest DOHC V6 family of gasoline engines. It will gradually replace the Mondeo family of V6 engines over the next several years. The first version, a 3.5 L Duratec V6, appeared in the 2007 Lincoln MKZ. Mazda badges its versions of the Cyclone MZI as it did with its versions of the Mondeo 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 Duratec 35 is ULEV-II compliant and is capable of meeting the PZEV requirement.
