Particulate Oxidation Catalyst（POC）

Primary Function
1.Particulate Matter (PM) Reduction
Reduces soot and other particulate emissions through oxidation reactions.
2.Reduced Exhaust Backpressure
Compared to DPF (Diesel Particulate Filter), POC has a more open structure, minimizing engine backpressure impact.
3.Extended DPF Regeneration Cycle
Acts as a pre-treatment device for DPF, reducing DPF load and prolonging regeneration intervals.

Feature
1.Material Composition
Porous ceramic substrate (e.g., cordierite or silicon carbide) .
2.Passive Regeneration Capability
Relies on exhaust high temperatures or catalysts to trigger particulate oxidation, eliminating the need for active regeneration systems.
3.Compatibility
Suitable for vehicles meeting mid-to-low emission standards or as a complementary technology to DPF.
4.Low Maintenance
No forced DPF regeneration required, offering a longer service life.
5.Lower Cost
Simpler structure than DPF, resulting in lower manufacturing and installation costs.
6.Limitations
Particulate capture efficiency (~50%-70%) is lower than DPF (>90%), requiring integration with other aftertreatment technologies.
