DPF System Export Parts Guide
For professional buyers: distributors, fleet maintenance, diesel workshops, and B2B importers. This guide helps you define correct scope for DPF-related parts and reduce mismatch risk using OEM reference.
Fast B2B sourcing rule: define your scope → confirm engine/variant → match by OE number → request quotation with quantities & destination.
1) What is a DPF system?
A Diesel Particulate Filter (DPF) is part of the aftertreatment system designed to reduce particulate emissions. Specifications differ by market and emission standard, so correct matching must be confirmed by OEM reference.
2) Common DPF clogging causes (service reality)
Operating conditions
- Short trips / low exhaust temperature
- High idle time
- Stop-and-go duty cycles
Engine-related factors
- Injector issues causing over-fueling
- Turbo or EGR problems
- Oil consumption increasing soot/ash
Maintenance factors
- Delayed regeneration / incomplete regen
- Incorrect service procedures
- Sensor or wiring issues
3) DPF service options (what to decide before ordering)
- Cleaning / regeneration support (service parts, gaskets, sensors depending on scope)
- Replacement (DPF unit + related gaskets/clamps + sensors as required)
- Diagnostics repair (pressure/temperature sensors, wiring, small components by OE reference)
4) Export parts scope checklist
- DPF unit (if replacement)
- DPF differential pressure sensor / exhaust temperature sensors (scope dependent)
- Gaskets, clamps, small seals (scope dependent)
- Related items: EGR/aftertreatment service parts (market dependent)
Tip: For export quotation, avoid “DPF parts” only. Specify what you actually need and confirm by OE reference.
5) Request Quotation (B2B Export)
Share your required scope with OE numbers and quantities. We confirm specification by OEM reference and prepare an export quotation.
