Diesel has had a bad reputation in recent years, but an increasingly popular technology is attempting to improve that image and make diesel vehicles feasible in the future. It is Diesel Exhaust Fluid, or DEF. On our website, you can find DEF 55 Gallon Drum and compare them by prices.
Now, you may also want to learn more about DEF. What is it, where can I get it and why do I need it? Everything you ever wanted to know about Diesel Exhaust Fluid and DEF 55 Gallon Drum is here.
What is Diesel Exhaust Fluid (DEF) ?
DEF (Diesel Exhaust Fluid) is a non-hazardous mixture of 32.5 percent urea and 67.5 percent deionized water. DEF is sprayed into diesel vehicles’ exhaust streams to break down harmful NOx emissions into harmless nitrogen and water. Selective Catalytic Reduction (SCR) is a system that can be found on 2010 and later model year vehicles, as well as many diesel pickups and SUVs. DEF isn’t a gasoline additive, and it’s never mixed with diesel. It’s kept in its own tank, usually with a blue filler cap.
To put it another way, the urea and water in DEF heat up and produce ammonia. The NOx emissions are subsequently neutralized as the ammonia breaks down. The tail pipe emits fewer harmful substances, allowing everyone to breathe a little better.
What is Selective Catalytic Reduction (SCR) ?
SCR technology breaks down hazardous NOx emissions produced by diesel engines into nitrogen and water using a catalyst system. A continual supply of ammonia gas is required for the chemical processes used in SCR systems. SCR uses a urea solution called Diesel Exhaust Fluid to provide ammonia in automotive applications (DEF). An sophisticated injection system sprays DEF into the exhaust stream, which is then converted to ammonia on a catalyst. The ammonia converts harmful NOx emissions from diesel engines into nitrogen and water.
Effects of DEF on the engine
The effects of what’s inside a DEF 55 Gallon Drum are simple: there are none. DEF bypasses the engine and interacts with the exhaust gas recirculation (EGR) system directly. A compressor, air reservoir, and regulating valve are occasionally used to manage the pressure in the tank, which is then injected before a catalytic converter.
How is a DEF 55 Gallon Drum used ?
In passenger trucks, Diesel Exhaust Fluid contained in DEF 55 Gallon Drum is used to reduce the harmful emissions of used diesel fuel, specifically nitrogen oxide (NOx) emissions. This is significant because, as the EPA points out, these highly reactive gases, which are produced when fuel is burned at high temperatures, are quite unpleasant—even deadly. “NOx is a strong oxidizing agent that plays a large role in atmospheric interactions with volatile organic molecules that form ozone (smog) on hot summer days,” says the EPA.
How to change Diesel Exhaust Fluid contained in a DEF 55 Gallon Drum?
After motor oil, another item to add to your list of routine maintenance is Diesel Exhaust Fluid, right ? Not to mention that it necessitates a little more care than other diesel fluids.
First, the requirements requiring DEF are quite stringent, requiring automakers to take them extremely seriously. Because your diesel truck is programmed to restrict engine power if you run out of DEF, this affects you. The average diesel truck uses around one gallon of DEF every 200-300 miles, despite receiving a warning when levels are low. This also happens to be the approximate duration of a tank of gas in your truck.
While you can always refill at a station, it’s a good idea to carry an additional gallon or two of DEF on hand.
It’s simple to fill up. Simply look for the DEF tank, which is normally marked with a blue filling lid and the words “Diesel Exhaust Fluid” (you guessed it). While some people have managed to confuse their diesel fluid and DEF tanks, this is a rare occurrence. “The standard DEF nozzle diameter is 0.75 inches (19mm), compared to 0.87 inches (22 mm) for diesel, prohibiting the diesel nozzle from ever being placed into the DEF tank,” according to the website. If you do mistake the two by chance or stupidity, come to a dealer as soon as possible and don’t drive the vehicle. Diesel gasoline, even in little volumes, can cause havoc with the system.
How to store a DEF 55 Gallon Drum ?
If you decide to have some DEF on hand, keep in mind that because it is a water-based solution, it will freeze in the winter. “A 32.5 percent solution of DEF will begin to crystallize and freeze at 12 °F (-11 °C),” according to Cummins Filtration. Both the urea and the water will freeze at the same rate at 32.5 percent, guaranteeing that the fluid does not become diluted or excessively concentrated as it thaws.”
It can also freeze in your tank, which is good news. Fortunately, the Selective Catalytic Reduction (SCR) system that allows DEF to break down NOx emissions is also intended to heat the tank and pipes, allowing everything to thaw properly—albeit slowly. Simply put, be careful where you keep your spare Diesel Exhaust Fluid and where you park your truck.
What is the shelf life of a DEF 55 Gallon Drum ?
Furthermore, DEF has a shelf life. Diesel Exhaust Fluid contained in a DEF 55 gallon drum typically lasts about two years. Expect that number to drop if it’s stored in a hot environment (over 86°F/30°C) or in direct sunlight. DEF is the least toxic of the fluids in your vehicle, but it should still be handled with caution. As a result, don’t store it in carbon steel, aluminum, copper, or zinc containers, as it will corrode the metal. It’s also worth mentioning that some vehicles have a filter in the DEF system, and you’ll want to keep an eye on it to make sure it’s in good working order.
