Diesel Cars Need Urea Here is the Real Reason and Its Benefits

Diesel: You may have heard individuals discussing urea being injected in new diesel vehicles, which tends to confuse most. This liquid, commonly referred to as AdBlue or DEF, has a larger role to play in the car than it seems. Let us dispel the mystery surrounding the need for diesel cars to use this unique fluid and what it does.

Why Urea is Added to Diesel Cars

Diesel cars emit poisonous gases from their engines, one of the most dangerous of which is nitrogen oxides. These harmful gases deteriorate air quality and even pose risks to human health. To regulate these emissions, most diesel engines these days employ Selective Catalytic Reduction technology, and that is where urea plays an important role. This magical solution assists in lowering deadly gases emitted through the exhaust.

How SCR Technology Works

The SCR system is one form of exhaust treatment. It reduces nitrogen oxide content by converting them into harmless gases. For this purpose, a liquid known as AdBlue or Diesel Exhaust Fluid is employed. The solution consists of 32.5% urea and 67.5% distilled water. As the exhaust gases pass through, this urea-containing fluid reacts with them, converting toxic nitrogen oxides into nitrogen and water vapor that do not contaminate the environment.

Significance of Urea Refilling

If your car is diesel-powered and has SCR technology, you need to replenish urea periodically. If you fail to do so in time, your car may not start or will lose power. In most automobiles, there is an independent tank and gauge to indicate the remaining AdBlue. If the reserve reduces, you will also notice a warning on the dashboard. Timely refilling guards your vehicle and the environment as well.

Urea Refill Cost and Frequency

Discussing money, the price of AdBlue is around ₹50 to ₹70 per liter. Typically, you would have to refill it between 7,000 to 10,000 kilometers. A tank typically holds between 10 and 20 liters. So the next time you are refilling AdBlue, keep in mind it is not any fluid but a significant contributor to preventing pollution and maintaining your diesel vehicle in good condition.
