Soot filter traps all soot particles and hydrocarbon.It needs to burn off the trapped soot particles.A key measure of its performance is the balance point temperature.The balance point temperature varies from engine to engine.
Balance point temperature: the engine operating condition and the exhaust temperature where soot burn off rate is greater than or equal to the engine soot output.

NOx Adsorber - How Does It Work?
It works in three simplified steps:
1. It stores NOx with normal diesel exhaust (Lean).
2. It releases NO2 when it is starved of O2 (Rich).
3. Under the rich condition, CO, HC, and H2 reduce
the released NO2 into N2.
