POC Cordierite Catalytic Converter for Gasoline Cars - High Flow Compliant Exhaust System
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.
