Diesel Exhaust Fluid (DEF) is a non-toxic solution used in modern diesel engines equipped with Selective Catalytic Reduction (SCR) systems to reduce nitrogen oxide (NOx) emissions. Vehicles requiring DEF typically have a separate tank for the fluid, which needs periodic refilling. Locating facilities offering DEF at the pump streamlines the refueling process for these vehicles, allowing for convenient and efficient replenishment alongside diesel fuel purchases. This is particularly relevant for commercial vehicles, such as trucks, that consume significant amounts of both fuel and DEF during operation.
The availability of DEF at fueling locations is crucial for maintaining optimal engine performance and adhering to environmental regulations. Using DEF compliant with ISO 22241 standards ensures proper function of the SCR system, leading to reduced emissions and potential cost savings through improved fuel efficiency. Historically, DEF was primarily available in containers, requiring drivers to manually pour the fluid into the tank. The introduction of DEF pumps at fueling stations marks a significant improvement in convenience and reduces the risk of spills and waste associated with containerized DEF.
