Why Is Diesel Exhaust Fluid So Important? What is DEF?

Why Is Diesel Exhaust Fluid So Important? What is DEF?

DEF's role in our lives has increased rapidly due to the day to day improvement in technology.

Nowadays DEF levels can be easily monitored by drivers if their vehicles are equipped with SCR technology.  Although these vehicles will be costly, the improved fuel potency could be a nice profit for companies as they appear to recoup prices related to conformity to DEF emission standards.

What is DEF?

Diesel engines burn fuel at a way higher temperature and pressure than gasoline engines. The heat permits them to be more efficient, however, it is also the speed at which oxygen reacts with nitrogen within the air to make pollutants, one among the main pollutants in automobile exhaust.

The big downside with nitrogen oxide is that you simply cannot use an everyday catalyst to get rid of it from the exhaust. And that's where the DEF comes in: The short answer is that DEF, or Diesel Exhaust Fluid, is an important component in keeping heavy-duty trucks and machinery operating within federal emission guidelines.

It's a solution of water and urea, a combination that decomposes into highly reactive ammonia gas when you heat it up. It is a resolution of water and organic compound, a mixture that decomposes into extremely reactive ammonia gas after you heat it up. They inject it into the hot exhaust before it goes through the cat, and within the cat the ammonia reacts with the nitrous oxide into harmless water and nitrogen.

At the beginning of 2010, DEF became a significant want for corporations using medium and heavy-duty diesel vehicles. Changes in EPA emission standards required reductions in diesel burning engines to scale back their pollution output to the bottom levels in history, and Selective Chemical Change Reduction (SCR) is the technology of alternative for original equipment makers (OEMs).

As this emission standard has changed to incorporate off-road vehicles, generators and a range of engines, DEF is getting used currently more than ever. Assume, as laws increase, DEF’s importance to keep emissions down can still be high.

Portable DEF Tanks

portable def tanks

Portable DEF tanks for diesel exhaust fluid containment and transport. Proformance Supply offers movable DEF organic compound compatible tote transfer systems in numerous capacities and voltages. All DEF storage tanks are compliant for diesel exhaust fluid storage. These are made from quality high-density polyethylene to produce fluid resistance, stability and minimize DEF crystallization issues with evaporation and associated pump cavitation.

Poly DEF tanks are made from FDA approved food-grade resin, are NSF 61 approved, and contain UV inhibitors to protect the tank and contents against sunlight damage.  These diesel exhaust fluid tanks are mainly used in the agriculture, automotive, forestry, industrial and transport industries. Compact, lightweight DEF tank pumping systems are available in 25 gallons to 100 gallon capacities. These separate tanks can be placed inside the beds of trucks, trailers, ATVs, or UTVs. They come with stainless steel pumps, delivery hoses, valves, and fittings. Nozzles have an automatic shut off feature.

The pumping compartment is completely enclosed and can be securely locked. These smaller DEF tanks have integrated handles for lifting, a 20’ hose, a 3/4’’ fill point, and a vane pump type.

Why is it becoming more important?

DEF (diesel exhaust fluid) has become the norm in many industries. It is required for large fleets and heavy machinery operations, both on job sites as well as in mobile or remote applications. The global benefits that begin with increased fuel efficiency and reduced emissions outweigh the minor inconvenience of having to add this fluid to our equipment as needed. The expanding offering of def tanks and dispense equipment continue to expand. Users are able to select from an array of equipment, specific to their needs and supply.

So, how exactly does SCR work and what role does DEF play in making that happen? We'll explain.

First of all, selective catalyst reduction is not new technology despite solely having been mandated by the independent agency within the last decade. It's been around for nearly half a century and was first used in the power generation industry to reduce oxides of nitrogen from coal-fired power plants.

It's that oxides of nitrogen thing that you need to keep in mind because its those compounds -- nitrogen monoxide and nitrogen dioxide -- that are the big problems with and they are what gave Volkswagen and their heap most bother.

What if I place one quart of DEF in an exceedingly full tank of diesel fuel?

DEF is 1/3 organic compound and 2/3 water. Like water, DEF would probably sink to the lowest of the fuel tank and be brought in by the fuel system. The fuel/water extractor would be overcome by a quart of DEF and it might travel on to the hard-hitting pump. Since the pump depends on diesel (a lightweight oil) for lubrication, there’s a decent probability the air mass pump would be broken.

Once the water hit the injectors, the engine would now stop running. With the system fully contaminated, it might need to be drained of all fuel, as well as the fuel tank to be cleansed and supplied with fresh diesel. If the hard-hitting pump survived the engine may start. If not, you'd need a replacement pump. Worst case, the price might run into thousands of dollars.

If there was not an attempt to start out the engine, the fuel tank should be drained and flushed instantly which would in all probability preclude any further damage.

Bulk DEF Storage Tanks

Bulk DEF storage tanks will hold hundreds to thousands of gallons of Diesel Exhaust Fluid (DEF). They're designed to support truck fleets of all sizes, which allows for the benefit of purchasing bulk DEF and having access at your own facility.

DEF corrodes certain materials, like steel, aluminium, copper and zinc. This corrosion will quickly contaminate the DEF and can harm the equipment. Bulk storage tanks are made of polyethylene plastic, fiberglass polyester, or stainless steel. These materials make sure that the quality of DEF is protected.

There is a large range of tank capacities and choices accessible for the installation of bulk def storage tanks. These units will need capital investment and careful thought has to be given to the pump system and heating needs. DEF fluid ought to be stored at a temperature between 14°F (-10°C) and 86°F (30°C), therefore a heating plant for your bulk tank is also needed in cold climates. Most mini-bulk units embrace a pump to dispense the DEF.

Conclusion

Modern technology has quickly tailored to DEF's role in our lives. Vehicles with SCR technology have displays on their dashboard that may simply alert the driving force on DEF levels. The improved fuel efficiency may be a nice profit for corporations as they appear to recoup prices related to conforming to DEF emission standards. Purchasing bulk quantities of DEF may be a notably important thought as we head into spring when seasonal spikes and probably higher prices, due to the planting season.
