Does Your Diesel Car Require Diesel Exhaust Fluid?

diesel exhaust fluid, exhaust fluidCar enthusiasts are always looking for ways to improve performance and reduce emissions output. Diesel car owners can achieve this through regular use of diesel exhaust fluid. Here’s how this simple addition to your vehicle can reduce harmful pollutants:

What Is Diesel Exhaust Fluid?

Diesel exhaust fluid is a solution consisting of deionized water and urea. Its purpose is to break down harmful nitrogen oxide in emissions and convert it into water and nitrogen. At no point does the diesel exhaust fluid come into contact with the diesel fuel. The two are stored in separate tanks.

How Does It Work?

Diesel engines operate on a precise air-to-fuel ratio. If the ratio is off and there is excess air, the combustion process produces nitrogen oxide, a harmful contaminant.

When the diesel exhaust fluid is injected into the exhaust system, the urea in the fluid produces ammonia. This element has a chemical reaction with NOx and converts it into nitrogen and H2O. Unlike NOx, nitrogen is harmless to the environment. H2O, or water, is obviously harmless.

Is Diesel Exhaust Fluid Compatible with Your Diesel Car?

Diesel cars require a selective catalytic reduction (SCR) system to be able to consume diesel exhaust fluid. SCR has been a mainstay in automotive technology for many years. However, it’s still somewhat of a novelty in diesel vehicles. All diesel cars built since 2010 have a SCR system.

You can find diesel exhaust fluid in local automotive stores. Some gas stations even have a diesel exhaust fluid pump next to the regular fuel pumps.
