Diesel Exhaust Fluid (DEF) plays a vital role in modern diesel engines by helping to lower emissions of nitrogen oxide (NOx) into the atmosphere. NOx is a primary pollutant that contributes to haze, smog, and health risks including respiratory and cardiovascular problems. DEF is a non-toxic, urea-based strainless solution that works in conjunction with Selective Catalytic Reduction (SCR) systems to convert NOx to harmless nitrogen and water vapor, enabling the engine to meet increasingly stringent environmental regulations such as the EPA emissions standards.

It is of key importance to fleet operators – truckers as well as those who operate buses and other commercial vehicles – to ensure that DEF levels are sufficient if those operators wish to cruise into gas stations for a refuel without entering automatic DEF jail. Apart from the inconvenience of reduced engine performance, increased fuel consumption, and potential regulatory fines, modern diesel engines are often programmed to reduce power, or even shut down in the absence of sufficient DEF. This makes it of paramount importance on the part of the fleet manager to keep the DEF tank at a satisfactory level.

TruckX provides fleet management services with real-time monitoring of DEF levels on all vehicles in the fleet, automatic low-DEF alerts, and granular information on DEF consumption trends to prevent fuel expense and allow operators to finetune DEF consumption. All this happens while guaranteeing full regulatory compliance.
