RICHER: The Core of a Top-Tier Automotive Emissions Aftertreatment Catalyst Company – R&D, Testing, and Validation Capabilities

Driven by increasingly stringent global emissions regulations (such as Euro VI/China VI), automotive emissions aftertreatment catalysts have become an indispensable core component of modern internal combustion engines. An outstanding company not only requires leading catalyst formulation technology but must also be equipped with comprehensive, state-of-the-art testing facilities and capabilities. This ensures that products meet the highest standards throughout the entire process from R&D and validation to mass production. This represents not only technical prowess but also a commitment to our customers and environmental responsibility.

Based on industry-leading practices, an excellent catalyst company should systematically develop and possess the following key testing facilities and capabilities:

1. Core Engine Test Bench Capabilities

This is the primary "battleground" for simulating real-world vehicle operation and comprehensively evaluating catalyst system performance, forming the foundation of R&D and validation.

• Heavy-Duty Diesel Engine Test Benches:

  • Facility Requirements:​ Should be equipped with high-power AC Dynamometers, capable of housing and testing a full range of diesel engines from light commercial vehicles to heavy-duty trucks (e.g., 2.5L to 13L+ displacement).

  • Core Competence:​ This platform is specifically used for catalyst performance evaluation, system aging, and client project development support. It must fully comply with all testing cycle requirements of the latest emissions regulations (Euro VI/China VI).

• Comprehensive Emissions Pollutant Analysis:

  • Test benches must integrate world-leading emissions analysis systems for real-time, precise measurement of all regulated gaseous and particulate pollutants, including but not limited to:

    • Gaseous Pollutants:​ Carbon Monoxide (CO), Hydrocarbons (HC), Nitrogen Oxides (NOx, including NO and NO₂), Ammonia (NH₃), Nitrous Oxide (N₂O).

    • Particulates:​ Particle Mass (PM) measurement via Partial Dilution Tunnels, and Particle Number (PN) detection capability.

• Integrated Aftertreatment System Testing:

  • The company must possess the capability to self-assemble complete Euro VI-level catalyst systems​ (e.g., inline canning) and integrate Urea Dosing Systems (SCR)​ and Hydrocarbon Dosing Systems (HC Dosing)​ on the bench. This allows for simulation and optimization of the entire aftertreatment system's performance under actual control strategies.

2. Front-End R&D & Rapid Prototype Evaluation

Efficient laboratory-level screening and evaluation are crucial before applying catalyst formulations to full-size systems.

• SCAT (Small Core Analysis Test) Laboratory:

  • Facility Setup:​ Core equipment includes gas blending systems, high-precision emissions analyzers, and high-temperature aging ovens.

  • Core Competence:​ This platform supports both gasoline and diesel catalyst product development. It enables rapid, cost-effective in-house testing and evaluation of new catalyst formulations for initial performance, light-off characteristics, and aging resistance potential, significantly accelerating R&D iteration speed for DPF, Three-Way Catalysts (TWC), DOC, SCR, and other aftermarket catalysts.

3. Precision Durability & Reliability Validation

Catalyst service life is a key performance metric, which must be verified through scientifically simulated aging.

• Professional Catalyst Aging Capabilities:

  • Should be equipped with multiple dedicated catalyst aging ovens/furnaces for precisely controlled hydrothermal aging tests.

  • Core Competence:

    • Targeted Aged Sample Preparation:​ Capable of preparing both aged samples​ and limit-aged samples​ for different catalyst types (e.g., DOC, CSF, SCR) that comply with OBD diagnostic requirements. This is used to evaluate catalyst lifespan limits and diagnostic thresholds.

    • Specialized Aging Simulation:​ Some aging ovens are equipped with gas blending systems to simulate aging under specific gas atmospheres, meeting more complex validation needs for Euro V/Euro VI and other aftertreatment catalysts.

4. In-Depth System Application & Engineering Support

An excellent company provides not just products, but deep solution expertise.

• Control Strategy & Calibration Support:

  • While not necessarily providing full Engine Control Unit (ECU) strategies, the company leverages its profound understanding of catalyst performance to offer optimized control recommendations​ to clients.

  • Possesses proprietary Urea Dosing and HC Dosing calibration systems, enabling the sharing of valuable dosing calibration and practical application experience​ with clients. This helps clients achieve faster and more optimal system integration and calibration for their vehicle emission control systems.

Conclusion

From the rapid prototype-screening lab to engine test benches simulating extreme conditions, and aging facilities validating long-term reliability, this complete, closed-loop testing capability system forms the essential technical infrastructure of a premier automotive emissions catalyst​ company. It ensures that every product performance enhancement and every durability promise is backed by solid data. This foundation builds trust in a competitive market and contributes reliable power to global clean mobility.

All of the above represents the core competencies that RICHER has meticulously built over more than a decade of dedicated focus on the internal combustion engine exhaust aftertreatment field. We specialize in diesel particulate filters (DPF), three-way catalysts, DOC, SCR systems, and comprehensive exhaust gas treatment solutions​ for both OEM and aftermarket catalyst​ applications, supporting standards from Euro V to Euro VI​ and beyond.
