AdBlue in Diesel Tank

What Happens When you have AdBlue in Diesel Tank

AdBlue in Diesel Tank is a painful, expensive and time consuming experience. AdBlue is a crucial component in modern diesel engines, designed to reduce harmful emissions and comply with strict environmental regulations. However, what happens when AdBlue ends up in your diesel tank? In this article, we will explore the potential consequences of this mishap, offering insights, real-life examples, and solutions to address this issue. Let\’s dive in!

\"AdBlueThe Role of AdBlue

Understanding AdBlue 

Before delving into the complications, it\’s essential to comprehend what AdBlue is and its role in diesel engines. AdBlue is a clear, non-toxic liquid made from urea and demineralized water. It\’s injected into the exhaust stream of diesel vehicles, where it undergoes a chemical reaction to convert harmful nitrogen oxides (NOx) into harmless nitrogen and water vapour. This process significantly reduces emissions and helps vehicles comply with stringent emission standards. AdBlue destroys seals and corrodes certain materials.

Diesel Engine Operation 

To better understand the potential consequences, let\’s briefly explore how a diesel engine operates. Diesel fuel is ignited by compression, resulting in the release of energy. AdBlue comes into play after the combustion process, working to neutralise harmful emissions in the exhaust gases.
