Ford Cyclone engine

The Cyclone is a family of double overhead camshaft gasoline V6 engines that Ford introduced in 2006, also branded Duratec. It succeeds the Essex, Vulcan, original Duratec V6 and Cologne V6 families, though it shares no parts or design with the earlier Duratec. Its features include displacements up to 4.0 litres, four valves per cylinder, direct acting mechanical bucket tappets and variable cam timing on the intake camshafts, with twin independent timing on later versions. The first version, a 3.5 litre V6, appeared in the 2007 Ford Edge and the Lincoln MKX and MKZ, and Mazda badges its versions MZI. Direct injection and turbocharging were added later as part of EcoBoost, and the 3.3 litre downsized version became the base F-150 engine in 2018.
