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 placed into a separate tank on the truck, and is simple to handle, non-toxic and safe for use. Diesel Exhaust Fluid (DEF) consumption is computed as a ratio of diesel fuel use, also called as the “dosing rate” or “treat rate”. Medium- and heavy-duty vehicles normally have a dosing rate of 2-3%. Here are a number of the most crucial things that you need to know about diesel exhaust fluid.

Roles 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 like those used for agricultural and construction has been mandated to use SCR technology since 2014.

Keeping DEF Pure

DEF purity is crucial. One essential aspect in maintaining DEF purity and quality is the kind of dispensing system used. Closed system containers feature a valve coupling system that fortifies the container opening on drums and totes (IBC) to prevent debris, dirt, bugs, etc from coming into the container and contaminating the DEF. By contrast, open system containers are drums or totes that do not include a valve insert in the container’s opening, which means that dirt or debris can infiltrate the container and contaminate the DEF.

Buying 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 orders all truck manufacturers to provide some kind of staged warning system (some include actual gauges) to inform the driver about precisely 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.
