CAUTION
Do not put diesel fuel in the Aftertreatment
DEF tank. Diesel fuel, if sprayed into the
hot exhaust along with the DEF, could
ignite explosively causing a fire resulting
in personal injury or damage to the exhaust
system.
The VOLVO SCR system is simple and effective, with few components. It consists of a
Aftertreatment DEF tank positioned near the standard diesel tank, plus a Aftertreatment
DEF pump, Aftertreatment DEF Dosing unit and SCR catalyst. The advantage of using
DEF is that it enables the engine to use less EGR -- and higher oxygen levels -- for better
combustion, while meeting the EPA near-zero NOx emissions requirement of 0.2 g/hp-hr
NOx. By using DEF, we avoid the disadvantages of increasing EGR to massive levels. This
results in better fuel economy from your VOLVO engine.
