THE REAL WORLD CHALLENGES

OF EMISSIONS COMPLIANCE

OEM and Aftertreatment teams must deliver compliant solutions under rising costs, complexity and risk. CATAGEN provides precise, repeatable, electrically driven emissions testing.

Increasing regulatory complexity

Tighter limits, more testing conditions and constantly evolving global standards.

Time and cost pressure

Engine based testing is expensive, slow to adapt and hard to scale with compressed development timelines.

Correlation and durability risk

Manufacturers must prove lab ageing and performance testing reflects real world catalyst and aftertreatment degradation.

New fuels and technologies

Hybridisation, alternative fuels, hydrogen, SAF and advanced catalyst materials introduce new degradation mechanisms legacy test struggle to replicate.

ELECTRICAL DRIVEN REACTOR TECHNOLOGY FOR EMISSIONS TESTING

CATAGEN’s OMEGA Technology is a proprietary, electrically driven reactor platform that replicates real-world catalyst and aftertreatment conditions without a full engine or vehicle system.

It enables accelerated ageing with high control and repeatability, reducing test cost, programme time and CO₂ emissions while delivering engine-representative, regulator-relevant results.

What this means for you: 

– Faster screening and development decisions 
– Consistent conditions for reliable comparison
– Reduced carbon footprint of testing programmes 

High control. High repeatability. Low emissions.

MV Augusta

CATAGEN proved to be a very reliable partner for our motorcycle catalyst ageing activities. From the early technical alignment through to project completion, the team demonstrated strong regulatory understanding, excellent planning discipline, and a clear focus on our homologation deadlines. 

The ageing programme was executed precisely as agreed, with fast turnaround and comprehensive documentation that allowed us to proceed confidently with our emissions validation. 

Their structured, engine-free approach and the consistency of the results made the overall process efficient and predictable. A further plus point is the friendly and kind nature of all the people I’ve worked with. We look forward to working with CATAGEN again.”

FRANCESCO VALENTINI
Head of Homologation and Regulatory Affairs. MV Agusta Motor S.p.A.

TVS

Our visit to CATAGEN Green Emissions Testing in Belfast, including the demonstration of the OMEGA reactor in operation, provided us with a high level of confidence in their methodology and the robustness of the data generated. 

The catalyst ageing programme was executed with precision, fully meeting our technical requirements, and was supported by rapid turnaround times and clear, comprehensive reporting.

CATAGEN’s extended prompt support throughout the programme played a significant role in ensuring its successful and timely completion, demonstrating their commitment to responsiveness and customer partnership. The combination of technical capability, operational excellence, and the professionalism consistently demonstrated by the CATAGEN team has been exemplary. We look forward to continuing our collaboration with CATAGEN Green Emissions Testing for our ongoing and future catalyst ageing needs, including forthcoming legislative programmes.”

NAGARAJAN R
Assistant General Manager – R&D

Volvo Penta

Thank you for a very successful collaboration where, with the help of CATAGEN, we developed an ageing cycle based on field data and aged mufflers, which was later used to verify our system.

This approach gave us increased confidence that the ageing conditions were representative of real-world operation, while also enabling us to move forward more efficiently with our development activities. The collaboration with CATAGEN allowed us to significantly reduce the overall project timeline.

ASKED QUESTIONS

What is Green Emissions Testing at CATAGEN?

Green Emissions Testing at CATAGEN is a suite of advanced emissions testing, catalyst ageing and durability services delivered using electrically driven reactor technology. It enables highly controlled, engine-representative testing without the need for a full engine or vehicle system.

 

CATAGEN Green Emissions Testing provides accelerated catalyst ageing, aftertreatment performance characterisation, diesel aftertreatment ageing and expert data interpretation to support aftertreatment and emissions development, correlation studies and regulatory compliance. We have also developed the OMEGA DAAAC reactor for diesel applications using the Diesel Aftertreatment Accelerated Ageing Cycle.  

 

How is CATAGEN's Green Emissions Testing different from traditional engine-based testing?

CATAGEN replaces continuous engine operation with a synthetic gas recirculating reactor (OMEGA Technology) that is powered electrically enabling precise control of temperature, gas composition and flow. This delivers faster, more repeatable ageing and durability testing while reducing cost, complexity and development time.

By eliminating the need for fuel-burning engine tests, CATAGEN’s electrically driven approach significantly reduces CO₂ emissions and operating costs. OMEGA and DAAAC enable accelerated, engine-representative testing with up to 98% CO₂ reduction and shorter test programmes.

 

What is Catalyst Ageing and why is it important for emissions compliance?

Catalyst ageing simulates long-term thermal and chemical degradation to understand how emissions performance changes over time. It is essential for demonstrating durability, correlation and compliance with emissions and OBD requirements prior to certification.

Can CATAGEN support alternative fuels and new powertrain technologies?

Yes. CATAGEN Green Emissions Testing supports hybrid powertrains, e-fuels, hydrogen combustion, biofuels, SAF and natural gas applications. Our flexible reactor-based approach allows operating conditions including gas species, chemical compounds, flow rates and temperatures to be adapted to evolving real-world environments.

Is CATAGEN Green Emissions Testing suitable for regulatory submissions?

CATAGEN’s emissions testing services are delivered through accredited facilities and regulator-recognised methodologies, supporting certification and approval activities with bodies including EPA, CARB, VCA, TÜV and other international technical services.

How do I get started with CATAGEN Green Emissions Testing?

The best way to get started is to speak with our emissions testing specialists. We work with customers to understand application requirements, development timelines and compliance objectives before defining an appropriate testing programme.
