We provide ageing services and testing to help motorcycle OEMs meet emissions targets faster and with higher accuracy and flexibility. Our process delivers accurate and reproducible outcomes for Full Useful Life (FUL), OBD Limits ageing and PGM Thrifting.

Motorcycle manufacturers all over the globe are facing emissions compliance challenges like never before. Emissions legislation is becoming ever  more stringent putting increased pressure on OEM to maintain low costs and ensure profitability. The global shift to electrification has drastically pushed up rare metal costs and new legislation is raising the bar for engineers to be able to meet the challenge. 

Euro 5 motorcycle emissions legalisation (and equivalent legislation globally) requires OEMs to test their OBD systems to show they will effectively work when emissions levels of CO, THC and NOx pass a threshold limit.

 

This legislation will come into effect for new vehicles in 2024 and existing vehicles in 2025.

 

CATAGEN  supports motorcycle OEMS:

    • To understand their ageing requirements to achieve OBD II emissions legislation targets. On Board Diagnostic (OBD II) is being introduced to additionally monitor the catalyst performance, through the installation of a downstream lambda sensor. The up and downstream lambda sensors then communicate with the Engine Management System (EMS) to check an Oxygen Storage Capacity (OSC) and hence, the activity status of the catalyst.
    • To optimise precious metal loading through material substitutions or quantity reduction to achieve emissions legislation targets
    • To understand OSC (Oxygen Storage Capacity) performance across a range of temperatures and flow rates
    • By providing guidelines for catalyst packaging in order to optimise performance by using aftertreatment simulation techniques to overcome design challenges and optimise for cost, size and aesthetics

CASE STUDY: PGM THRIFTING

Challenge

To meet emissions legislation and develop an effective aftertreatment system, a number of key areas need to be considered:

    • Cost – price of precious metals such as Rhodium, impacting production costs.
    • Compliance – engine manufacturers need to guarantee compliance at the point of sale and throughout the lifetime of the vehicle in real life scenarios with a range of changing variables
    •  Legislation – this has led many engine manufacturers to decrease the size of their engines and over specify their aftertreatment parts.

Approach

The services offered by Catagen provide powertrain engineers an insight into their aftertreatment systems in the following ways:

    • Detailed Chemical analysis – provides a detailed chemical breakdown of the aftertreatment device, focusing on key components such as the PGM and washcoat composition.
    • Reproducible Performance testing – provides the activity analysis of the aftertreatment part, giving an understanding of how well the part will perform.
Cold Start Emissions for Motorcycles

Results

CATAGEN’s testing services provide a substantial benefit to the engine manufacturers, providing clarity, confidence and understanding of their parts. With this knowledge in hand an optimisation strategy can reduce cost of the part and of the vehicle.

This provides a more informed starting position for the next generation of powertrain, reducing development time and cost in the future.
