Diesel Car Urea: Heard of a liquid form of urea used in filling diesel vehicles? Although it’s usual to link urea with agriculture, it has an unexpected function in cars as well. Most vehicle owners still don’t know the reasons why it is utilized or how it works. Let’s dissect its function and learn why it’s increasingly becoming a necessity in new diesel vehicles.
Why Diesel Cars Use Urea
You may have heard or witnessed a liquid called urea being injected in diesel vehicles. Technically, it’s referred to as Diesel Exhaust Fluid (DEF) or AdBlue. Diesel motors emit toxic gases when they burn, and one of the most significant pollutants is Nitrogen Oxide (NOx). The gases contribute to air pollution and can adversely affect human health. Urea neutralizes these emissions and makes the exhaust clean.
Urea Cleans Up Emissions
As a result of the implementation of BS6 emission standards in India, diesel vehicles are now required to adhere to tighter pollution controls. This prompted companies to use SCR technology—Selective Catalytic Reduction. It injects a urea-based liquid into the exhaust gas. The primary work of this process is to lower Nitrogen Oxide emissions and convert them into harmless nitrogen and water.
How Urea Functions Within a Diesel Car
Urea is kept in a separate tank in the vehicle, and it is normally found under the name AdBlue. When the vehicle engine is running, the exhaust gases flow through a catalyst system. In this system, the urea solution is sprayed and heated up to high temperatures, turning it into ammonia. This ammonia reacts with the toxic NOx gases and degrades them into nitrogen and water vapour. These by-products are safe and do not pollute the environment.
Why AdBlue is Important to Diesel Car Owners
For those who own or are thinking of purchasing a diesel car, it’s crucial to know about AdBlue. It’s not merely a matter of complying with emissions requirements; it’s also about having a clean environment. Keeping AdBlue refilled on time makes your diesel car perform better while lowering pollution. It’s an easy action that produces a tremendous impact.
