How do I add diesel exhaust fluid?

DEF can be found in all truck stops and auto parts stores. It is a non-toxic liquid that can be handled without any special protective clothing or tools. To add more DEF, simply locate the fill port — it is usually found under the hood, next to the fuel port or in the trunk — and top it off manually.

How do you use DEF?

DEF consumption will be approximately 2\% of the diesel fuel consumed. Another way to consider it is that DEF will be consumed on a 50 to 1 ratio with diesel. (For every 50 gallons of diesel fuel burned, you will use 1 gallon of DEF).

What happens if you put diesel exhaust fluid in your diesel tank?

What Happens If I Put Diesel into a DEF Tank? Diesel is less dense than DEF, so it will float on the DEF. If it enters the SCR catalyst, significant damage can occur that may require servicing or even worse, a (costly) replacement of the catalyst.

How often do you add diesel exhaust fluid?

For example, for every 100 gallons of diesel fuel consumed, between 2 and 4 gallons of DEF will be automatically injected into the exhaust system. The typical DEF tank will be approximately 15 – 20 gallons, thus requiring a fill every 5,000 to 6,000 miles.

Is diesel exhaust fluid the same as AdBlue?

Diesel Exhaust Fluid (DEF) also known as AdBlue®, is a non-toxic, colourless, odourless and non-flammable fluid. Stored in a dedicated tank in your car, it is injected into the exhaust system to clean exhaust gases. In addition to a new generation of catalytic converter, SCR Technology requires the use of DEF.

How does diesel exhaust fluid system work?

Small quantities of diesel exhaust fluid (DEF) are injected into the exhaust upstream of a catalyst, where it vaporizes and decomposes to form ammonia and carbon dioxide. The ammonia (NH3) is the desired product which in conjunction to the SCR catalyst, converts the NOx to harmless nitrogen (N2) and water (H2O).

What does DEF do to diesel exhaust?

Diesel Exhaust Fluid (DEF) is a solution of urea and water that’s injected into the exhaust stream of diesel vehicles to turn NOx gases (harmful emissions) into nitrogen and water. This system is called a Selective Catalytic Reduction (SCR) implemented by vehicle manufacturers to meet EPA emissions standards in 2010.

What happens when you run out of DEF?

If the truck is allowed to run out of DEF the engine’s power is reduced, a solid red warning will be displayed and the vehicle speed will be limited to 5 mph until the DEF tank is refilled.

Is DEF bad for diesel engines?

While it’s good for the environment, the water and urea mixture can result in the formation of crystals that can plug up fuel filters, damage aircraft engines, and result in engine failure. DEF should never be used as an additive for any fuel, diesel or aircraft, and is sprayed directly into exhaust systems.

Will a small amount of DEF in diesel tank?

Truck owners and operators must not allow even a small amount of DEF in their diesel tanks. This will cause contamination of the diesel fuel system. DEF is a solution of urea and water. Diesel fuel and water-based DEF have different densities and will not mix.

What is the purpose of diesel exhaust fluid?

In 2010, the EPA required diesel engines to reduce their production of (NOx) nitrogen oxides. That reduction is accomplished with the additive Diesel Exhaust Fluid (DEF). This fluid reduces NOx and air pollution. So it helps heavy machinery and trucks operate within the federal emissions guidelines.

What is diesel exhaust fluid and how does it work?

How Diesel Exhaust Fluid Works: When injected into the exhaust stream with a specialized dosing module, BlueDEF’s water vaporizes, leaving ammonia molecules en route to the catalytic converter; once there, it converts NOx molecules into harmless nitrogen and water vapor—making for cleaner emissions.

What year trucks require Def?

What Year Chevrolet and GMC Trucks Require DEF? In 2007, Duramax produced a 6.6L engine with new diesel particulate filter technology. However they didn’t start using DEF until 2010 in response to 2010 EPA regulations. In 2011 General Motors released the latest in its Duramax line, labeled the LML. This version introduced advanced emission controls, including diesel exhaust fluid injection.

Diesel exhaust fluid, or DEF, is designed for use in SCR systems to reduce nitrogen oxide emissions. It is a urea-based chemical produced from raw fossil fuel sources such as natural gas, coal, and a variety of other petroleum based products by dissolving solid urea of high purity in de-ionized water.

What do you need to know about diesel exhaust systems?

It would help if you had a snorkel. As we all know,our 4×4 vehicles can be put through the wringer,so we need to do our best to
