AVL will present the impact on R&D emission testing of vehicles and engines by Post Euro-6.

The upcoming emission regulation Post Euro-6 will affect pure ICE as well as hybrid, battery or fuel cell electric vehicles. For the development of such vehicles there are the challenges of a growing number of sample probe locations along the complex exhaust aftertreatment systems, the flow rates of extracted sample and the required floor space for additional measurement equipment.

Key takeaways:

  • Engine-out and mid-cat measurements at sample points with high pressures and temperatures will be necessary in addition to tailpipe sampling for all components.

  • DPF and GPF will be needed to fulfill particle limits, requiring particle number and transient soot measurement to develop soot loading and regeneration models.

  • Complex exhaust aftertreatment systems require a higher number of exhaust gas sampling points, so extracted samples must not affect the engine and the exhaust aftertreatment system.

  • Frontloading and validation: To cope with RDE requirements, RDE cycles need to be run early in the development cycle, not only in chassis dynos but also in powertrain and engine testbeds.
