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 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. == 3.5 L == 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), 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. Ford expects the engine to be available in 20% of its vehicles by the end of the decade. Official SAE certified engine output is and on 87 octane gas. This is a substantial upgrade in power from the Duratec 30 and bested all comparable 87 octane rated V6 engines at the time of its launch.〔(【引用サイトリンク】title=Ford's new V-6 catches up to competitors )〕 For 2011, the 3.5 L received Ti-VCT, helping to boost output to and . The 3.5 L's highest output to date is . This version is used in the redesigned Ford Explorer. The engine is assembled at Lima Engine in Lima, Ohio, with expansion planned in Cleveland Engine Plant #1. The 3.5 L was on the Ward's 10 Best Engines list for 2007. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ford Cyclone engine」の詳細全文を読む スポンサード リンク
