Diesel exhaust fluid (def) is added to diesel to help convert nitrogen oxide (nox) emissions into nitrogen and water. This helps diesel engines meet the strict emissions. To drain a def (diesel exhaust fluid) tank, wait until the tank is completely empty and then rinse it out with warm water. Once cleaned, refill the tank with fresh def. I see the benefit from this as being that if you get def crystallization in your tank and lines, you could potentially flush the system with tap water instead of replacing everything.
There will be no urea sprayed into the exhaust to convert to ammonia if you put water in an empty def tank. Ammonia is required to remove. This was actually a very good question, whether you can fill the def tank with water (distilled, deionized, not tap) instead of def. The def isn't necessary to prevent. If you put water in an empty def tank, there will be no urea injected into the exhaust to convert to ammonia. Ammonia is an essential requirement to eliminate skip to content Water in diesel exhaust fluid (def) tanks is bad news — whether the tanks store def in bulk or in smaller amounts within diesel engine vehicles. Because of the harmful. Understanding def (diesel exhaust fluid) is crucial for maintaining optimal performance in diesel engines. The water / def is used to complete a circuit between the base electrode at the bottom of the tank and any of the three electrodes at higher heights in the tank. Putting diesel exhaust fluid directly into your fuel tank can lead to a seized engine, expensive repair work, or maybe even a new car. What happens if you put a small amount of def in diesel tank? Mixing def (diesel exhaust fluid) with diesel fuel can lead to serious consequences for your vehicle. If you put water in an empty def tank, there will be no urea injected into the exhaust to convert to ammonia. Ammonia is an essential requirement to eliminate nox.
