Understanding Why the Utilization of Blue DEF in Your Vehicle Is Mandatory

If you use most types of diesel engines within your Florida business, whether in the form of heavy equipment, truck engines, and many other types, you know that you need to use DEF in your vehicle. It’s mandatory under US law. Why is that, though? While you can purchase high-quality fluid from a Blue DEF distributor, why is it necessary in the first place?

DEF, or diesel exhaust fluid, is used by a vehicle’s selective catalytic reduction system. It is sprayed into the exhaust system while the engine is running to reduce the amount of NOx created during operation and use. The liquid is sprayed onto a catalyst within the exhaust system, which transforms DEF into ammonia. When the ammonia contacts NOx, it converts it into something harmless. DEF is composed of urea and de-ionized water, and transforms NOx into nitrogen and water, transforming what would ordinarily become smog and acid rain into two elements necessary for life on earth.

In addition to eliminating NOx from your fleet’s emissions, buying and using diesel exhaust fluid from a Blue DEF distributor will help improve fuel economy. Because dosing with DEF occurs in the exhaust system, rather than in the engine, it’s possible to improve the tuning of engines to improve fuel consumption and power output.

How much DEF will you need to use within your fleet vehicles? That’s a difficult quest to ask, as it’s related to diesel fuel consumption. In short, the more fuel your fleet consumes, the higher your consumption of Blue DEF will be. In general, a medium or heavy-duty diesel vehicle will require a dosing rate of 2 – 3% (DEF to fuel). In essence, a diesel vehicle with a fuel efficiency rating of six miles per gallon and a dosing rate of 3% will use roughly one gallon of DEF per 200 miles of usage.

Of course, you do need to work with the right Blue DEF distributor. Look for a company that can supply you with whatever volume of diesel exhaust fluid is necessary to keep your fleet running and in compliance with EPA regulations at an affordable cost, without any unexpected outages. Remember that the EPA requires you to use DEF in your diesel fleet vehicles, and failure to do so can result in costly fines and even more costly vehicle downtime.
