What Is Diesel Exhaust Fluid?

What Is Diesel Exhaust Fluid?

The United States Environmental Protection Agency created new emissions standards in January of 2010 that required medium and heavy-duty diesel engine vehicles to reduce their engine emissions drastically. One of the ways this was accomplished and implemented is with the use of diesel exhaust fluid, or DEF. If you have a diesel engine, DEF is something that you should be familiar with. If you are not, now is a great time to learn more about it. Here is some information about diesel exhaust fuel. 

What is Diesel Exhaust Fluid?

Diesel exhaust fluid is a clear liquid that is injected into the exhaust stream of a vehicle with a diesel engine. Newer vehicles with diesel engines have a catalytic converter that features a DEF dosing valve. This prevents you from having to inject the liquid yourself. However, the valve has to be refilled as needed. As you drive a diesel engine, the exhaust gas travels from the engine and out of your car. When diesel exhaust fluid is placed into the exhaust system, the exhaust gas hits the liquid, which causes it to vaporize. It then turns into an ammonia and carbon dioxide vaporization, which is safer for the environment. 

What is Diesel Exhaust Fluid Made From?

Diesel exhaust fluid is made from 32.5 percent urea and 67.5 percent de-ionized water. Urea is a natural ammonia by-product that is readily available and environmentally-friendly. This is why this type of liquid is clear and has a slight scent of ammonia to it. 

By law, medium and heavy-duty trucks and vehicles must have their emissions within a certain level. If your vehicle is producing more emissions than it should, you may be unable to register your vehicle or could even receive a fine from the EPA.

What are the Benefits of Using Diesel Exhaust Fluid?

The biggest benefit of using diesel exhaust fluid is that you are doing your part to help the environment. By law, medium and heavy-duty trucks and vehicles must have their emissions within a certain level. If your vehicle is producing more emissions than it should, you may be unable to register your vehicle or could even receive a fine from the EPA. DEF helps to ensure your emissions are within the levels allowed by law. 

The other benefit to using diesel exhaust fluid is that it helps to keep your emissions system cleaner. Ultimately, this helps to extend the life of your emissions system, which can reduce the amount of care, maintenance, and replacement parts your emission system needs.
