Everything You Should Know about Diesel Exhaust Fluid
Diesel Exhaust Fluid (DEF) refers to a high quality operating fluid that is employed in combination with diesel vehicles and selective catalytic reduction (SCR) technology. It is a 32.5% solution of high-purity, synthetically created, urea in de-mineralized water. It is located in a separate tank on the vehicle, and is easy to deal with, non-toxic and safe for use. Diesel Exhaust Fluid (DEF) consumption is quantified as a ratio of diesel fuel use, also known as the “dosing rate” or “treat rate”. Medium- and heavy-duty vehicles typically have a dosing rate of 2-3%. Below are a few of the most essential things that you must know about diesel exhaust fluid.
Functions of DEF
Majority of the diesel-powered on-road vehicles manufactured since 2010 make use of SCR technology and require DEF. Several examples are heavy-duty trucks, diesel pick-ups, delivery vans, and European luxury cars. Diesel powered off-road equipment such as those utilized in agricultural and construction has been required to use SCR technology since 2014.
Keeping DEF Pure
DEF purity is vital. One significant factor consideration in preserving DEF purity and quality is the kind of dispensing system employed. Closed system containers have a valve coupling system that protects the container opening on drums and totes (IBC) to prevent debris, dirt, bugs, etc from getting into the container and contaminating the DEF. On the other hand, open system containers are drums or totes that do not feature a valve insert in the container’s opening, which signifies that dirt or debris can get into the container and contaminate the DEF.
Owing to the fact that majority of diesel-powered passenger cars and trucks manufactured since 2010 are furnished with Selective Catalytic Reduction (SCR) and require DEF, it is can easily be bought at most fueling stations. Truck stops also normally have a DEF pump right on the fuel island. You can also find DEF at most OEM stores, as well as other dealers and distributors.
Running Out of DEF
The EPA mandates all truck manufacturers to integrate some kind of staged warning system (some offer actual gauges) to make the driver know about exactly how close to empty the system is. Whether a vehicle goes into a “limp home” or decreased engine power or restrains the number of times you can turn the engine on will be reliant on the actual car or truck model, but at some point it will not start. In essence, you should treat your DEF tank the same way you treat your fuel tank; you definitely do not want to leave yourself stranded because you did not pay attention to the indicators.
