Everything You Should Know about Diesel Exhaust Fluid
Diesel Exhaust Fluid (DEF) is the term for a high quality operating fluid that is utilized together 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 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%. 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. Some 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.
How to Maintain DEF Purity
DEF purity is critical. One significant factor consideration in preserving DEF purity and quality is the kind of dispensing system employed. Closed system containers involve a valve coupling system that secures the container opening on drums and totes (IBC) to prevent debris, dirt, bugs, etc from gaining access to the container and contaminating the DEF. Contrastingly, open system containers are drums or totes that do not have a valve insert in the container’s opening, which implies that dirt or debris can get into the container and pollute 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 Low on DEF
The EPA directs all truck manufacturers to include some type of staged warning system (some provide actual gauges) to let the the driver be aware about exactly how near to empty the system is. Whether a vehicle goes into a “limp home” or lower engine power or constrains the number of times you can turn the engine on will be dependent on the specific car or truck model, but at some point it will not start. To put it simply, you should treat your DEF tank the same way you treat your fuel tank; you surely do not want to leave yourself stranded because you failed to notice the indicators.
