Volvo, US10 Emissions Solution 349
System Operation
1 Diesel engine optimized for high performance, low particle emissions and low
fuel consumption.
2
Aftertreatment DEF tank
3
The Aftertreatment Control Module (ACM) continuously monitors and adjusts the
Aftertreatment DEF pump pressure in response to current engine load conditions.
4
DEF is injected into the exhaust gases in between the Aftertreatment DPF (5)
and the SCR catalyst (6).
5 Aftertreatment Diesel Particulate Filter (DPF).
6
In the SCR catalyst, nitrogen oxides are transformed into harmless nitrogen gas
and water.
7 The system notifies the driver when it is time to refill tank with DEF.
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.
