To evaluate whether a CDPF (Catalyzed Diesel Particulate Filter) complies with Euro V or Euro VI emission regulations, consider the following key factors: Precious Metal Catalyst Type & Loading A compliant CDPF must be coated with sufficient amounts of platinum (Pt), palladium (Pd), or similar catalysts to enable efficient oxidation of soot and NO at low temperatures. Filtration Efficiency and Regeneration Capability The DPF should achieve a PM filtration efficiency of over 90% and feature passive or active regeneration mechanisms to prevent clogging. Lab-Based Emission Testing Certified third-party laboratories (e.g., TUV, SGS) should validate that the engine fitted with the CDPF meets or exceeds Euro V/VI limits for PM, CO, and NOx emissions. Structural Design and Cell Density (CPSI) CDPFs designed for high emission standards typically use high CPSI substrates (e.g., 400 CPSI) to increase contact area and filtration performance. Compliance Certifications Verify if the product has passed CE, EPA, CARB, or other recognized emission control certifications or has test reports available. Real-World Performance Feedback Vehicle inspection results and customer use cases can offer practical insight into whether the CDPF performs up to Euro V/VI expectations.

Can CDPFs Be Customized? Which Shape is Better: Round, Square, or Oval? Yes, CDPFs (Catalyzed Diesel Particulate Filters) support customization in terms of dimensions, shape, CPSI (cells per square inch), substrate material (cordierite or silicon carbide), and catalyst loading formulas. This allows CDPFs to be tailored to different vehicle types, installation conditions, and emission targets. There are three main structural shapes commonly available: round, square, and oval. Choosing the best one depends on space constraints, exhaust layout, and system performance needs. 1. Round Structure Advantages: Widely compatible, uniform flow, easy to integrate Recommended for: Trucks, buses, small gensets 2.
