Power Stroke is the name used by a family of diesel engines for trucks produced by Ford Motor Company and Navistar International (until 2010) for Ford products since 1994. Along with its use in the Ford F-Series (including the Ford Super Duty trucks), applications include the Ford E-Series, Ford Excursion, and Ford LCF commercial truck. The name was also used for a diesel engine used in South American production of the Ford Ranger. From 1994, the Power Stroke engine family existed as a re-branding of engines produced by Navistar International, sharing engines with its medium-duty truck lines. Since the 2011 introduction of the 6.7 L Power Stroke V8, Ford has designed and produced its own diesel engines. During its production, the PowerStroke engine range has been marketed against large-block V8 (and V10) gasoline engines along with the General Motors Duramax V8 and the Dodge Cummins B-Series inline-six. Engine family list 7.3 Power Stroke The first engine to bear the Power Stroke name, the 7.3 L Power Stroke V8 is the Ford version of the Navistar T444E turbo-diesel V8. Introduced in 1994 as the replacement for the 7.3 L IDI V8, the Power Stroke/T444E is a completely new design, with only its bore and stroke dimensions common with its predecessor (resulting in its identical displacement). In line with the IDI diesel, the Power Stroke was offered in three-quarter-ton and larger versions of the Ford F-Series and Econoline product ranges. The Power Stroke is an electronically controlled, direct injection engine with a bore and stroke creating a displacement of . It has a 17.5:1 compression ratio, and a dry weight of approximately . This engine produces up to and of torque in automatic transmission trucks from the last years of production, and and of torque in manual transmission trucks. The oil pan holds while the top end (due to the HPOP) holds an additional , making for a total of of oil contained within the engine. The 1994.5 to 1996/97 DI Power Stroke has "single shot" HEUI (hydraulically actuated electronic unit injection) fuel injectors which were AA code injectors unless from California where as they received AB code injectors. It ran a high pressure oil pump (HPOP) to create the necessary oil pressure to fire the fuel injectors. This generation of Power Stroke utilizes an HPOP with a 15° swash plate angle. The 1995-1997 trucks use a two-stage cam-driven fuel pump, whereas
