half-dozen.7L Power Stroke Diesel
half-dozen.7L Power Stroke Specs & information
Codenamed the Scorpion during its developmental stage, the 6.7L Power Stroke is Ford'due south in-firm built diesel engine for the Ford Super Duty. Ford chose to design, engineer, and produce its own diesel engine to maintain profitability and a competitive edge in the growing diesel fuel segment. This is the outset Power Stroke not manufactured by long time partner, International Navistar. The absence of a partner seems to have given Ford an reward over competitors, granting them the freedom to design an engine that fits their specific needs and the needs of their customers. Additionally, information technology streamlines the warranty process, which was partially responsible for souring the human relationship between Ford and International in regards to problems with the 6.0L. The Ford, International partnership lasted nearly 30 years, merely Ford seems to be doing simply fine on their own.
Equally with whatever new engine, potential truck buyers initially questioned the platform'due south reliability despite reports of extensive durability testing. Fortunately, Ford seems to accept hit a home run with the 6.7L, which impresses in the departments of performance, fuel economic system, reliability, and as we're slowly finding out, longevity. Over 500,000 6.7L Power Strokes were sold in the engine's first three years of production.
The six.7L Power Stroke initially employed a unique unmarried sequential turbocharger (SST) which features a dual compressor and single turbine setup affixed to a mutual shaft. The unit was replaced past a unmarried Garrett GT37 variable geometry turbocharger (VGT) for the 2015 model twelvemonth, subsequently increasing horsepower and torque in combination with additional upgrades. The SST returned to the Power Stroke for the completely revised 2017 model year Super Duty; torque reached an all fourth dimension loftier at 925 lb-ft. Both horsepower and torque were in one case again increased for the 2018 model year, peaking at 450 hp and 935 lb-ft, respectively. Ford suggests that software adjustments, cylinder caput improvements, and increased turbocharger boost are responsible for the increases.
Also unique is the engine'south exhaust and intake manifold designs. As opposed to a tradition V engine, the intake and exhaust flows are reversed - the intake manifolds are located on the outer deck of the cylinder head and the exhaust manifolds exit directly into the engine valley where the turbocharger is mounted. The unique exhaust menstruum design is said to increase thermal efficiency of the turbocharger.
2020 6.7L Power Stroke Updates & Changes
For 2020 Ford introduced the tertiary Generation vi.7L Ability Stroke diesel, rated at an impressive peak i,050 lb-ft of a torque and 475 horsepower. While the revised engine features a number of significant changes, the near noteworthy is probable its new piston pattern. For 2020, the Power Stroke utilizes a steel piston with a relatively brusque overall height. Shrinking the acme of the piston compensates for the increased weight of steel, a much heavier material than the previous aluminum pattern. The result is a piston that is comparable (albeit slightly heavier) in weight to the pre-2020 piston, but offers increased force/resilience and lower friction due to its smaller contour. The 3rd generation 6.7L Power Stroke features the following additional revisions:
• Revised variable geometry turbocharger
• Compression ratio lowered from 16.2 : 1 to 15.8 : one (corresponds with new piston design)
• Updated cylinder caput design
• Revised connecting rod and primary bearing designs
• Engine block enhancements
• Carve up stream piston cooling jets (contributes to piston cooling and cylinder wall lubrication)
• New two piece lower intake manifold
• Revised injection system with maximum 36,000 psi injection pressure level, new fuel injectors capable of viii injection events per combustion cycle
• 10R140 ten speed automatic transmission replaces outgoing 6R140 TorqShift

6.7L Power Stroke Emissions System Overview
• Exhaust gas recirculation (EGR). A unique feature of the 6.7L Power Stroke is that EGR menstruation is controlled by the EGR valve prior to entering the EGR cooler, as opposed to cooling the exhaust gases before EGR menstruum is managed. This post-cooling organization reduces sludge and soot buildup in the EGR valve, minimizing maintenance.
• Diesel fuel oxidation catalyst (DOC). The Doctor is a ceramic catalytic converter designed to oxidize hydrocarbons in the exhaust stream.
• Selective catalyst reduction (SCR). The SCR is where diesel fuel exhaust fluid (DEF; 32.5% urea) is injected & mixed into the exhaust stream. Diesel fuel exhaust fluid is used to convert nitrous oxides into h2o & nitrogen. DEF fluid level must be maintained to ensure proper operation of the system and the truck (an empty DEF tank will outcome in reduced performance and speed).
• Diesel particulate filter (DPF). The DPF captures diesel particulate matter (soot) and uses active regeneration engineering to heat the exhaust organisation periodically, completely burning soot build up & cleaning the filter.
Additional half dozen.7L Power Stroke Info/Features
• The 6.7L Power Stroke engine blocks are manufactured by American foundry company, Tupy. The engines are assembled in Chihuahua, Mexico.
• Ford Motor Company announced new power ratings for the 6.7L Power Stroke on August third, 2010. Owners of the 390 hp model were able to receive a free dealer installed upgrade to achieve the new 400 hp power rating.
• The pre-production half dozen.7L Power Stroke was nicknamed the "Scorpion" due to its unique turbocharger mounting location and exhaust/intake organization.
• Engine features half dozen bolt main bearing caps.
• "Instant Start" glow plugs are said to provide quicker starts in even the coldest of weather.
• Compacted graphite atomic number 26 block for reduced weight (160 lbs lighter than the half dozen.4L Power Stroke).
• Engine uses fractured cap Mahle connecting rods.
• Features piston cooling jets for lower piston temperatures. Oil is jetted into the bottom or the piston and travels through a cavity within the piston, cooling the acme of the piston before exiting. This helps lower combustion temperatures and increase engine longevity.
• B20 biodiesel uniform.
• vi.7L Power Stroke receives 18% increase in fuel mileage over previous six.4L engines.
• The 6.7L Power Stroke diesel and TorqShift transmission are used in applications up to 50,000 lbs GCWR (F-650, F-750 models).
