Title: Corail Blanc - Fashion Jewellery Store Online

7.3 Liter PowerStroke Engine The first 7.3L was
produced from 1988-1993. The original 7.3L diesel
was a non-turbo charged indirect injection (IDI)
engine, followed shortly after by a turbo charged
version. It was very similar to the previous 6.9l
IDI diesel engine, which was simply bored out for
more torque. This engine is not considered in the
powerstroke family. In 1994, the 7.3L underwent
some changes. The 7.3L was changed to a direct
injection (DI) engine from the original IDI
engine.
The 7.3L Power Stroke turbo diesel is
characterized by its HEUI (hydraulic electric
unit injector) injection system, which uses
highly pressurized engine oil as a medium for
creating fuel pressure directly in the injector
body, as a opposed to a system requiring a
typical injector pump. In lieu of an injection
pump, the 7.3L PowerStroke utilizes a high
pressure oil pump (HPOP) and a low pressure lift
pump in order to create fuel pressures up to
21,000 psi. In comparison to the prior mechanical
injection system, the transition to HEUI promised
improved performance, lower emissions, and better
fuel economy stemming from increased fuel
atomization and greater control over injection
events.

7.3 Liter PowerStroke Engine The popularity of
Ford's International powered F-Series pickups is
distinguishable in its production numbers, which
greatly exceeded that of any competing
manufacturer's diesel sales. By 1999, 1 million
PowerStroke equipped trucks had been delivered to
dealerships. As demand soared following Ford's
introduction of the Super Duty platform, the 2
millionth 7.3L Power Stroke equipped F-Series
rolled off the assembly line in 2002. The 7.3L
Power Stroke has earned praise as one of the most
popular engines offered in a pickup truck, its
name synonymous with reliability and longevity.
A greater demand for fuel economy and
significantly lower emissions ultimately led to
the retirement of the 7.3L during the 2003 model
year. For the 2003 MY, the 7.3L Power Stroke was
offered alongside the new, smaller 6.0L Power
Stroke. By the beginning of the 2004 MY, the 6.0L
Power Stroke had completely replaced the 7.3L.

7.3 Liter PowerStroke Engine
Block and Head The 7.3 L Powerstroke used cast
iron head and block, which also helps explain the
excellent durability. The valvetrain for the
power stroke was overhead valves, with 2 valves
per cylinder. This means a single intake and
exhaust valve per cylinder. These are driven by a
standard push rod camshaft. The 7.3L Powerstroke
offered many significant improvements over its
predecessor, the 7.3 L IDI, or indirect
injection. The Powerstroke was well known for its
endurance and reliability.
