6.7L Powerstroke Information

After the problematic 6.0L and also 6.4L Powerstroke engines, Ford severed ties with worldwide Navistar and built their very own Powerstroke diesel engine, in-house, nicknamed the “Scorpion”. The Scorpion 6.7L Powerstroke diesel engine gotten in Ford’s Superduty lineup in 2011 and hasn’t left since. Upon its release, it developed 390 horsepower and 735 lb-ft that torque. Soon after, Ford actually issued an update that adjusted factory tuning, bringing the van to 400 horsepower and 800 lb-ft that torque. Back the numbers are impressive, Ford likewise managed to make the 6.7L Powerstroke their most emissions-friendly diesel come date and increase fuel economic climate dramatically. Just how did they traction this off? I’ll provide you every the 6.7L Powerstroke specifications below and also explain what make this diesel engine so special, that it’s still supplied in Ford’s Superduty van 10 year after it to be introduced.

6.7L Powerstroke performance Specifications

Ford had actually to get their diesel engine right. ~ the problems with both the 6.0 and also 6.4, buyers were shedding confidence in Ford’s Superduty lineup. To enhance engine durability, Ford’s “Scorpion” 6.7L Powerstroke engine functions a CGI or Compacted Graphite iron block. It’s a stronger material than cast iron, and is an ext resilient to extra horsepower and also torque. The block itself has actually a deep-skirt design, and Ford gotten rid of the bed plate the was existing on the 6.4 and also 6.0L Powerstroke engines. Nodular iron key caps save the crankshaft placed firmly in location by six bolts each.

The forged-steel connecting rods have proven themselves capable of withstanding more horsepower and torque than most diesel owners will ever see being created from your trucks. The connecting rods re-superstructure a comparable design to the which is found on Cummins powered diesel trucks. By clocking the large bearing journals, the big end that the rod deserve to fit into the block. Cast-Aluminum pistons are also used ~ above the 6.7L Powerstroke and include offset pistons pins and also a solitary oil cooling galley.

Reverse flow Heads

One that the most interesting features that the 6.7L Powerstroke is the usage of cast-aluminum reverse-flow cylinder heads. Air enters v the valve covers and also exits indigenous the lifter valley. As a result, the 6.7L Powerstroke services from lessened turbo lag.

Overall, the 6.7 has actually 32 valves, equating to 4 valves every cylinder. 4 rockers and also four pushrods are also found every cylinder. Unequal the previous 6.4L Powerstroke, No rocker bridges are used. This is thought to be among the reasons this engine is for this reason quiet.

Cooling System

Another among the 6.7l Powerstroke’s inexplicable specifications is the use of two unique cooling systems. The major cooling device is responsible for cooling the engine. A an additional cooling device is offered to cool a brand-new air-to-water intercooler, infection fluid, fuel cooler, and also EGR system. Come circulate the coolant, two separate belt-driven pumps space used. When this is contempt more facility than traditional cooling system designs, I like that the EGR cooling is kept separate indigenous engine cooling. Top top the 6.4L and 6.0L Powerstroke coolant frequently damaged down because of it’s exposure to excessive heat in the EGR system. Particles would then travel with the cooling system and also be exposed to every little thing else. This mechanism keeps coolant separate.

The Air-To-Water intercooler not just saves a incredible amount of space, but it additionally offers exceptional cooling characteristics. The 6.7L Powerstroke’s air-to-water intercooler provides it v cooler, denser air while all at once reducing boost-drop compared to typical air-to-air intercoolers.

6.7L Powerstroke Turbochargers

Two various turbochargers are offered on 2011-2016 6.7L Powerstroke-equipped trucks. The original turbocharger was a collection sequential, variable-geometry turbocharger the was offered until 2015. 2015 and 2016 6.7L Powerstrokes usage a Garrett GT37 turbocharger.

2011-2014 SST Turbochargers

This turbocharger is pretty tiny compared to the turbochargers used in the LML Duramax or 6.7L Cummins. In spite of it’s small design, power is nice impressive. This turbocharger is waste-gated and also uses two small compressor wheels, two air inlets, and also a sphere bearing facility cartridge. Essentially, the solitary sequential turbocharger performs similar to a link turbocharger set-up. Unfortunately, this turbo frequently causes problems on early on 6.7L Powerstrokes. Friend can uncover out more about 6.7L Powerstroke turbocharger fail here.

2015-2016 Garrett GT37 Turbochargers

In 2015, Ford replaced the SST turbocharger through Garretts G37 change geometry turbocharger. It’s a an ext basic non-wastegated design. The G37 is the desired turbocharger top top 6.7L Powerstroke trucks because it offers enhanced high-altitude performance and also exhaust braking. The G37 turbocharger additionally experiences considerably less failures 보다 the previous single sequential turbocharger.

6.7L Powerstroke Fuel Injection

The 6.7L Powerstroke’s common rail fuel injection system functions a Bosch CP4.2 injection pump and piezoelectric injectors. This fuel system not only supplies impressive performance, but it additionally makes the engine exceptionally quiet. In 2015, Ford enhanced the 6.7L Powerstroke’s fuel injection system. The CP4.2’s stroke to be improved, adding an ext fuel flow. The Piezo-electric injectors nozzle tips were also improved, giving a finer fuel spray. This changes, along with the modification turbocharger style are responsible for the 15′ and also later 6.7L Powerstroke’s higher horsepower and torque numbers.

6.7L Powerstroke CP4.2 Injection Pump Failures

Similar to the LML Duramax, as soon as the CP4.2 injection pump fails, it sends shrapnel right into the entire fuel system leading to expensive repairs. That method you could have come clean your whole fuel system and also replace the injectors and also injection pump. Pay special attention to the fuel you put into your 6.7l Powerstroke. The CP4.2 is an extremely sensitive to negative fuel or fuel air pollution of any sorts. Replace your 6.7L Powerstroke Fuel filters often.

Emissions Reduced and Reliability Increased

Ford’s 6.7L Powerstroke featured new specifications the made it premium to the previous 6.0L or 6.4L Powerstroke. A new emissions system called Selective Catalytic Reduction aided reduce emissions by up to 80% compared to the 2010 model. By injecting diesel exhaust liquid into the exhaust stream, emissions are reduced prior to they go into the Diesel Particulate Filter. This reasons the quantity of “regens” to significantly decrease. Renewal requires fuel come be provided to increase exhaust gas temperatures and burn off staying diesel particulates (Soot) indigenous the filter. By to reduce the amount of regenerations that occur, friend improve as whole fuel economic situation too.

The exhaust gas recirculation device (EGR) was a nightmare for 6.0L and 6.4L Powerstroke owners. The architecture was prone to regular clogs and also malfunctions that could an outcome in high-quality repairs. Ford’s 6.7L Powerstroke attributes an enhanced EGR design. The new EGR Valve regulates exhaust gases before they reach the EGR Coolers to help decrease sludge build-up and clogging. The 2 EGR Coolers are also housed in the same casing and can expand and also contract come decrease opportunity of failure.

Ford flourished in improving the EGR mechanism as EGR related failures are far less common on the 6.7 보다 previous Powerstroke generations.
