DPF

DPF Solutions for Different Fleet Applications

A DPF replacement requirement can vary depending on how a vehicle is operated, the engine configuration, emission standard, and existing exhaust system. Yongyong therefore approaches DPF supply from the application rather than treating every vehicle as the same.

Our products support a range of commercial and fleet applications.

Port & Container Fleets: A Key Application

Port and container transportation is one of the important applications supported by Yongyong. Trucks serving marine terminals, container yards, warehouses, rail facilities, and distribution centers may complete repeated daily routes and spend significant time in loading, unloading, queuing, and local freight operations.

For these fleets, DPF sourcing is closely connected with maintenance planning. When a replacement filter is required, the maintenance team needs to identify the correct application and obtain the required component without introducing unnecessary vehicle downtime.

Yongyong supports port-related fleet requirements through OE-number-based DPF matching, repeat supply of established references, bulk orders, and evaluation of non-listed applications.

At the same time, our DPF range is not limited to port drayage. The same product identification and manufacturing approach can support regional transportation, long-haul freight, construction, distribution, and other heavy-duty commercial vehicle applications.

Stock for Regular Demand: Manufacturing for Special Applications

Fleet customers often need both immediate replacement products and reliable long-term supply.

For regular DPF references, available stock can help support replacement demand. For less common, discontinued, newly required, or non-listed applications, Yongyong can evaluate the OE number and application information for manufacturing.

This gives fleet maintenance companies and aftermarket customers two sourcing options:

Regular References → Stock Availability

Special Applications → OE-Based Manufacturing

For recurring fleet requirements, customers can also discuss product references, expected quantities, and supply schedules with our team.

Why OE Number Matching Matters

The truck brand and model provide useful information, but they may not be enough to identify a replacement DPF.

Different engine configurations, production years, emission standards, and exhaust system designs can result in different DPF specifications within the same vehicle brand or model family.

그리고 OE number provides a more specific reference for identifying the required component.

When requesting a DPF, we recommend providing the OE number whenever it is available. Additional information can then be used to verify the application.

Information Used for DPF Matching

• OE number or reference number
• Truck brand
• Truck model
• 엔진 모델
• Vehicle year
• 배출 기준
• DPF dimensions
• Inlet and outlet configuration
• Mounting structure
• Sensor locations
• Existing product photos
• Required quantity

If you only have the OE number, send it first. Our team can advise what additional information may be required.

Match Your DPF by Truck Brand and OE Number

Yongyong’s DPF range covers selected applications across major truck and diesel engine brands. The table below provides a starting point for product identification.

OE numbers are provided for identification and cross-reference purposes. Product compatibility should be confirmed according to the specific vehicle, engine, and exhaust application.

DPF Matching by Vehicle, Engine and Exhaust System

An OE number is the preferred starting point, but product compatibility also depends on the complete application.

Yongyong evaluates relevant information including:

• Truck brand and model
• 엔진 모델
• Vehicle year
• 배출 기준
• OE number
• DPF dimensions
• Inlet and outlet configuration
• Mounting points
• Sensor locations
• Existing product photos

This helps distinguish between DPFs that may look similar but are designed for different applications.

DPF, DOC and Replacement Components

Yongyong’s product range covers the DPF itself and selected components used in diesel exhaust aftertreatment and DPF replacement.

Product	애플리케이션
디젤 미립자 필터(DPF)	Main particulate filtration component
디젤 산화 촉매(DOC)	Exhaust oxidation applications
DPF 클램프	Exhaust and DPF connections
DPF 개스킷	Sealing between exhaust components
DPF 키트	Selected replacement combinations
Sensors & Related Parts	Applicable aftertreatment systems

For customers managing fleet maintenance or aftermarket distribution, related components can be sourced together with established DPF references.

OE-Based DPF Manufacturing

Yongyong develops and manufactures aftermarket DPFs around specific OE references and vehicle applications.

For a non-listed product, our team can review the available OE number, vehicle and engine information, dimensions, photos, and exhaust configuration.

This provides a practical route for customers who need:

• A replacement for a non-listed OE reference
• Additional supply for an established application
• Fleet-specific DPF sourcing
• New aftermarket product development
• Bulk production based on a confirmed reference

DPF Quality Control

DPF replacement requires more than matching a product’s external shape. Dimensional accuracy, sealing, airflow characteristics, materials, and coating are all relevant to product quality.

Yongyong applies inspection and testing procedures to control key manufacturing characteristics.

Dimensional Inspection

Key dimensions and connection points are checked against the confirmed product specifications to help maintain consistency between production batches.

Air-Tightness Testing

Relevant DPF assemblies are checked for sealing performance and potential leakage around the housing and connections.

Backpressure Testing

Backpressure testing is used as part of DPF quality control to evaluate airflow characteristics against applicable product requirements.

Material and Coating Control

Material selection and catalytic coating are controlled according to the requirements of the applicable DPF product and application.

How to Request the Right DPF

Send the information you have:

• OE Number: The preferred product reference.
• Vehicle Information: Truck brand, model, engine, and year.
• Application Information: Emission standard and exhaust configuration when available.
• Product Photos or Dimensions: Useful when the OE number is unavailable or needs verification.
• Required Quantity: Important for fleet and wholesale quotations.

If you only have the OE number, send it first. We can advise what additional information is needed.

자주 묻는 질문

How do I know if an aftermarket DPF is compatible with my truck?

Compatibility depends on more than the truck brand. The OE reference, engine, emission configuration, DPF dimensions, mounting structure, inlet and outlet connections, and sensor locations should be checked together. Providing the original DPF number and photos allows our team to verify the application more accurately.

Can you supply different DPF models for a mixed truck fleet?

Yes. Fleet customers can provide multiple OE references covering different truck brands, models, or engine configurations. Yongyong can evaluate the references individually and consolidate suitable DPF requirements into one sourcing program.

What should I do if the original DPF has no readable OE number?

The DPF can still be evaluated using the truck model, engine model, vehicle year, emission standard, dimensions, connection configuration, and clear product photos. These details help identify the application when the original reference is unavailable.

Can you develop a DPF for an application that is not in your catalog?

Yes. Yongyong can evaluate non-listed applications based on an OE reference or available product and vehicle information. After the application and required specifications are confirmed, an aftermarket replacement solution can be considered.

Can you supply the DPF together with clamps, gaskets, or other replacement parts?

Yes. Selected DPF-related components can be supplied with the main filter, depending on the application. This can help fleet maintenance teams, repair businesses, and distributors source commonly required replacement parts together.

How do you handle repeat orders for fleet maintenance?

Once a DPF reference and application have been confirmed, the same OE-based identification can be used for subsequent orders. Customers can also provide a list of regularly required references to support ongoing fleet replenishment.

Can one DPF reference be used across different truck models?

Not necessarily. The same or similar-looking DPF may have different applications, configurations, or mounting arrangements. Compatibility should be confirmed against the OE reference and complete vehicle or engine application before supply.

Do you support DPF requirements for port and container fleets?

Yes. Port and container transportation is one of the key applications we support. We also supply DPF solutions for regional freight, long-haul trucking, construction, distribution, repair, and other commercial vehicle operations.

What information is required for a bulk DPF quotation?

For a bulk quotation, provide the OE references, required quantities, truck or engine applications, and any specific packaging or delivery requirements. A list of multiple OE numbers is also acceptable for mixed-fleet or distributor orders.

Can you manufacture DPFs based on an existing sample?

Sample-based evaluation may be possible depending on the application and available technical information. An original DPF, OE reference, dimensions, and vehicle or engine data can help establish the required specifications for assessment.
