Aftertreatment 1 SCR Conversion Efficiency- The U.S. Environmental Protection Agency (EPA) requires all on-highway heavy duty diesel engines to meet a NOx emission standard of 0.20 g/bhp-hr. To meet this standard, most engines use a technology called selective catalytic reduction (SCR).

The HC-SCR uses HC as a reductant agent. However, in spite of its advantages, namely no NH3 dosing, low material cost [12], and systemic simplicity, HC-SCR could not be chosen for diesel NOx reduction because of its low NOx conversion efficiency at low temperatures [12].SPN 4364 FMI 18: NOx conversion efficiency low – The SCR system is not effectively reducing NOx emissions, which could be caused by a variety of issues, such as low DEF …• AS035 SCR Inlet NOx Sensor • AS036 SCR Outlet NOx Sensor • AS101 NOx Conversion Efficiency WARNING: ENGINE EXHAUST To avoid injury from inhaling engine exhaust, ...
