Boss is the internal name for a family of large displacement V8 engines from Ford Motor Company intended to compete with Chrysler Hemi engines and General Motors' 6.2 L Vortec engines. Originally, Ford developed the engine architecture under the name Hurricane; however, development of the engine was delayed due to its temporary cancellation in 2005. It was revived in early 2006 by Mark Fields and was given the new name of ''Boss'' in light of the devastation caused by Hurricane Katrina in 2005.〔(McGuire, Bill. Ford's Experimental Racing Engine - Roddin' At Random. Hot Rod Magazine. )〕 In spite of this change Ford has yet to officially market the engines with the Boss name in any production vehicle where they are to be used, instead referring to the engines by their displacement. The first Boss engine, a 6.2 L V8, is produced at Ford's Romeo Engine Plant in Romeo, Michigan.〔(Ford Motor Company. "Robust, Ford Tough: All-New 6.2-Liter Gasoline Engine Complements 2011 Ford Super Duty." Ford Media. 24 September 2009. )〕 Ford Australia and Ford Performance Vehicles used the "Boss" name for V8 engines from 2002 but these are variations of the Ford Modular V8 with locally-produced parts. ==6.2 L== The V8 is the main variant of the Boss engine. The V8 shares design similarities with the Modular engine family such as a deep-skirt block with cross-bolted main caps, crankshaft driven gerotor oil pump, overhead cam valve train arrangement, and bellhousing bolt pattern. In particular, the 6.2 L V8 features a 2-valve per cylinder SOHC valve train with roller-rocker shafts and two spark plugs per cylinder as well as dual-equal variable cam timing. While notable that they use a much wider bore spacing (compared to the Modular's ), allowing for the use of larger bore diameters and valves. The 6.2 L V8 has a bore diameter of with a stroke. The 6.2 L V8 has lightweight aluminum cylinder heads and pistons but makes use of a cast iron cylinder block for extra durability since most applications for the engine will be trucks.〔 The 6.2 L V8 went into production in early 2010 and debuted in the 2010 Ford F-150 SVT Raptor as a late-availability option. A limited edition version of the Raptor from Ford Racing called the Raptor XT features a high output version of the 6.2 L V8 with approximately .〔(Ford Motor Company. "F-150 SVT Raptor Most Powerful Half-Ton Available, Now Even More Capable Off-Road." Ford Media. 3 November 2009. )〕 For the 2011 model year, the 6.2 L V8 was introduced in Ford's Super Duty pickups as a replacement for both the 5.4 L Triton V8 and the 6.8 L Triton V10 and in the F-150 as the premium engine option, though it is not available in all configurations.〔 ''Applications for the 16-valve SOHC VCT 6.2 L V8 include the following:'' * 2010 F-150 SVT Raptor, @ 5500 rpm, @ 4500 rpm * 2011 Ford F-Series, @ 5500 rpm, @ 4500 rpm * 2011 Ford F-Series Super Duty, @ 5500 rpm, @ 4500 rpm〔http://media.fordvehicles.com/article_display.cfm?article_id=32097〕 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 Boss engine」の詳細全文を読む スポンサード リンク
