2011 Ford Super Duty Diesel Exhaust Fluid (DEF) Tutorial

DEF FAST FACTS

Injection of DEF to reduce NOx is a proven technology used throughout the auto industry. Unlike other manufacturers’ solutions, the DEF system allows the diesel engine to run at its optimum range in terms of fuel mixture – some systems require the engine to run richer, which can be harmful to diesel engines, to control the NOx.

  • DEF is a solution of approximately one-third high-purity urea and two-thirds demineralized water that is clear, nontoxic and safe to handle.
  • DEF tank, supply module and supply line are heated to help ensure DEF remains in a liquid state, preventing it from freezing while in operation or thawing from a frozen state.
  • DEF is injected into the exhaust system, to greatly reduce NOx levels.
  • The DEF tank includes temperature and fluid level sensors, and when the level reaches an approximate 800 mile distance-to-empty level, an instrument cluster warning alerts the driver.
  • On Pickups, the DEF tank and fill nozzle are located together with the diesel fuel tank and fill nozzle on the driver’s side of the vehicle and require refilling at oil-change intervals.
