With the proliferation of RDE throughout global emissions regulations tied with increasingly stringent future emissions standards such as EU7, China 6b and SULEV20, there needs to be a shift in the methods used to develop powertrains.

In this free webinar, MAHLE Powertrain‘s Simon Williams and Matt Grove, discuss the company’s RDE process, which when used in conjunction with a transient DoE approach to create accurate particulate number (PN) models, helps stakeholders meet future powertrain development challenges.

Key topics and takeaways:

  • MAHLE Powertrain’s view on the latest worldwide CO2 regulations and EU7 legislation requirements for future powertrain development
  • Methods for front-loading development programs to improve powertrain testing efficiency and meet the challenge of future legalisation
  • MAHLE Powertrain’s transient design of experiments optimisation process linked to model-based calibration methods to demonstrate powertrain program efficiency savings utilising offline calibration optimisation
  • Results from customer projects showing a greater than 60% PN reduction over a range of drive cycles utilising the model-based calibration approach whilst reducing time requirements on engine testbed and vehicle
