CATAGEN APPROACH
CATAGEN helps automotive OEMs meet emissions targets faster, with higher accuracy and repeatability. Our unique OMEGA technology can replicate engine flow rates, temperatures and gas compositions for any kind of engine. Accredited by UK Vehicle Certification Agency (VCA), Applus IDIADA, TUV ATEEL and ECO Cert.
We offer tailored services to support OEMs to meet aftertreatment development milestones and emissions compliance (homologation). We help manage development issues with the catalyst ageing process and help manage cost implications such as PGM prices and the rising cost of fuel.
The OMEGA is capable of thermal and chemical degradation of aftertreatment components. Our chemical degradation is through a bespoke poisoning setup which can be used for a range of different compounds such as, sulphur and phosphorus which can help with OBD limit ageing.
STANDARD BENCH CYCLE (SBC)
CATAGEN use the Standard Road Cycle (SRC) data that our partners supply to calculate the Bench Ageing Time (BAT) or we conduct the SBC at a prescribed time and temperature criteria on request of our partners.
FUEL CUT AGEING
Fuel cut ageing uses a combination of high temperature and lean conditions to age after treatment systems.
Catalyst temperature, fuel cut duration and frequency can be altered to match individual customer requirements.
ON BOARD DIAGNOSTIC (OBD)
Current emissions legalisation requires OEMs to have fully tested On Board Diagnostic (OBD) systems. To test these systems OBD aged catalysts and sensors are essential.
We use a series of high-temperature ageing techniques to age components to meet a customer’s individual OBD requirements.
LAMBDA / AIR FUEL RATIO SWEEP (AFR)
Lambda sweep tests are used to assess PGM and wash coat degradation. These tests are carried out on the CATAGEN flow-through reactor, facilitating excellent control of gas composition.
BESPOKE /NON STANDARD DURABILITY CYCLES
Our aftertreatment ageing experience and toolset can be used to help customers develop and test new aftertreatment systems for a range of applications.
Our extensive toolset including the use of full-scale characterisation, ageing, poisoning and modelling capabilities alongside the ability to create a full range of transients makes us the ideal partner to help develop new products or product applications. With our patented OMEGA technology, CATAGEN can use a series of control techniques to create new aftertreatment ageing cycles to match individual customer requirements.
OXYGEN STORAGE CAPACITY TEST (OSC)
The CATAGEN OSC measurement procedure involves cycling the catalyst between lean and rich conditions, with full oxidation and reduction of the ceria at each condition. The OSC value is calculated through several different methods across both oxidation and reduction reactions, including analysis of the λ signals, analysis of raw emissions data and analysis of the reactant delivery.
CATAGEN can replicate vehicle conditions as long as our partners can share the mass flow rate and engine out temperature at the measurement point on the vehicle. This allows for very strong correlation on OSC measurement between CATAGEN & our partners.
