The CATAGEN ageing approach has been used by global OEMs for development & homologation requirements. CATAGEN conduct all aftertreatment ageing and characterisation at full scale on aftertreatment systems using internationally patented technology The OMEGA; a Synthetic Gas Recirculating Reactor.
Our OMEGA technology allows us to match your desired catalyst temperatures, emissions and mass flows and add additional compounds to the gas composition such as ammonia for diesel accelerated ageing. Using our technology we can perform a range of characterisation tests for heavy-duty applications to understand performance of the aftertreatment component over time such as, Ammonia Storage Test, NOx/NH3 Ratio Tests & NO/NH3 Light-Off Tests.
Using our physical and virtual toolset we can track the ageing experience in real time using the proprietary CATAGEN Ageing Metric. This metric can be used to quantify the total ageing experience and help design ageing protocols and cycles for the development of representative aftertreatment components.
The key focus for heavy duty manufacturers with increasingly stringent emissions standards include:
- Design and implementation of an accelerated ageing protocol representative of real-world
- Cost of ageing on an engine
- Diesel PN (Particle Number) limits
- Engine calibration for a wide range of engine operation conditions (speed, torque, temperatures, altitudes) to meet “Real Driving Emissions” limits.
- CO2 reporting not only by g/k/Wh for the engine, but a whole vehicle approach. Most likely combining engine test data with a vehicle software simulation approach
- Testing definition for HD vehicle Hybrid-powertrains.
- A potential NO2 limit
- Reduced fuel consumption or alternative e-fuels such as hydrogen fuel cells
INDUSTRY EMISSIONS LEGISLATION
The Euro VI-D legislation for heavy-duty engines approvals entered into force on 1 September 2018 for new types and has applied to all new engines from 1 September 2019. The Euro VI-E entered into force on 1 September 2020 for new types and will apply to all new engines from 1 September 2021. This stage includes consideration of cold-start emissions in data evaluation of the PEMS testing, as well as the measurement and evaluation of PN during the on-road test.
Particle Number (PN) measurement will be included in Euro VI Step E from the beginning for compression ignition engines. For positive ignition engines (natural gas mainly in heavy duty) the PN will need to be declared for monitoring purposes for new type approved vehicles from 01/01/2021 and will need to be complied with from 01/01/2023.
