Exhaust Aftertreatment
Diesel Engine Exhaust Aftertreatment Device
Description
Diesel engine exhaust after-treatment device, include diesel oxidation catalyst(DOC), diesel particulate filter(DPF), particulate oxidation catalyst(POC), catalytic diesel particulate filter (CDPF), selective catalytic reduction (SCR), etc.. They can reduce the harmful matters such as particulate matter(PM), CO, HC, NOX, and turn them into nontoxic matters such as CO2, H2O and N2 etc. to release. Diesel engine exhaust after-treatment devices are widely used on bus, truck, fork truck, crane, construction machinery, light and heavy duty vehicles in OEM and service markets, and can meet the emission standard Euro 4, Euro 5, Euro 6, EPA and CARB.

| Item | Product Description | |
|---|---|---|
| DOC | Funciton | 1.Oxidize HC and CO in diesel exhaust gas emission |
| 2.Oxidize the SOF of particulate matters (PM) | ||
| 3.Partially oxidize the SOOT of PM | ||
| 4. Coated catalyst on the POC surface to oxidize PM | ||
| 5.As the first stage of the SCR catalyst, oxidize NO into NO2 to improve the conversion efficiency of NOx | ||
| Feature | DOC have excellent oxidation performance, low light-off temperature for HC,CO and SOF, high conversion efficiency. Good restrain for sulfate forming. | |
| Main series | 1. DOC+DPF/POC (match with POC/DPF) can provide the oxidation temperature of PM to help regenerate. | |
| 2.DOC+SCR (match with SCR) oxidize NO into NO2,improve the conversion efficiency of NOx | ||
| Application | All on road and non-road vehicle, heavy duty diesel vehicle,and various construction machinery and diesel power generator set. | |
| Substrate material | Metallic and ceramic | |
| Cell density | 300CPSI, 400CPSI | |
