Acronym definitions, intro to the 6.7 engine and commonly asked questions.

The 6.7l was a new clean sheet engine design introduced with the 2011 Ford Super Duty. The engine was designed by Ford, and is built by Ford in Mexico.
The 2011-2014 6.7 engines are available in 2 configurations, the version available in the F-250, F-350 and F-450 pickup (400hp, 800lbft), and the version available in the F-350, F-450 and F-550 cab chassis (300hp, 660lbft). The basic engine is the same between these 2 version, but there are some key differences (turbocharger, engine calibration etc.)
Its basic layout of the engine is a V8 diesel with direct common rail injection. The flow of the heads is opposite of most production engines (exhaust ports are in the valley of the engine).
The 2011-2014 engines have a conventional Garrett GT32 turbocharger, with the pickup trucks having a 2 stage compressor wheel. The 2015+ engines will have a GT37 turbocharger.
The engine block is made from Composite Graphite Iron (CGI), a high strength steel, with Aluminum heads.
Other unique features are the 2 separate cooling systems a high temp one (194 degrees to cool the engine) and a low temp one (122 degrees to cool the air-to-water intercooler, transmission fluid, fuel cooler, and EGR system).
The 6.7l diesel was the first diesel engine in a Ford pickup to be fitted with Urea injection, and has a quite complex emissions system.

Common Acronyms/names.

6R140 - the name for the transmission fitted to all 2011+ (diesel or 6.2 gas) trucks. It stands for 6 speed and that it will accept 1,400 lb.ft of input torque.

DEF - Diesel Exhaust Fluid. Also potentially called SCR (Selective Catalytic Reduction) or Urea Injection. This system is new on the 6.7l trucks, and it is a fluid that gets injected into the exhaust of the truck to reduce its NOx output. The filling system for this is located next to the diesel tank filler, and it will need to be topped up every ~5,000 miles or so. Almost all modern generation diesels use a system similar to this.

DPF - Diesel Particulate Filter. This is a system fitted to the exhaust of all 2008+ PSD's that "traps" particulates and soot. Periodically this filter needs to have its soot contents disposed of - something the engine does automatically by "regen'ing". The 6.7l does this less frequently than the previous 6.4l PSD due to the addition of the DEF system.

EGR - Exhaust Gas Recirculation. This system selectively pulls some exhaust gas through a cooler and into the intake of the engine.

Emissions system - As mentioned the emissions system on a 6.7l is complex, and involves the EGR, a Catalytic Converter, DEF and DPF.
Here is a diagram of the post turbo exhaust system.

"Flash" - This is what updating the engine or transmission calibration is called.

PSD - Power Stroke Diesel. What Ford has called the diesel engines it has fitted to its pickup trucks since 1994.5. 7.3l PSD 94.5-03, 6.0l PSD 03-07, 6.4 PSD 08-10, 6.7 PSD 11-?

Regen - this is the process the engine goes through to eliminate the soot in the DPF. There are 2 ways this can happen. Active regen - a message comes up on the info screen briefly when the truck is undergoing an Active regen, and you will notice the instantaneous milage drop. The truck essentially injects a lot more fuel than normal into the left hand bank (drivers side) to really heat up the exhaust system to burn the soot out. Lots of stop/start driving with the engine not getting hot will cause this to occur more frequently. Passive regen, when the truck engine gets really hot (usually only while towing a large load), the DPF will begin burning soot off of its own accord. This process doesn't involve injecting additional fuel and you will not receive a message on the info screen when this is occurring, nor should you notice a drop in milage.
