Guest Speaker: Paul Boucharel - Leading technical expert - Powertrain system analysis at Continental.

Today around 25% of global emissions are generated by the automotive industry.  This has resulted in a big challenge for the industry to find ways to reduce these harmful exhaust gas emissions.  Managing exhaust gas emissions requires several different strategies beyond the internal combustion engine and after-treatment systems.  These strategies are influenced by a number of different factors which should be considered: these include but are not limited to vehicle variants, powertrain electrification, control strategies, after-treatment system design and architecture, and driving cycle scenarios.

Evaluating numerous concepts and design is challenging, and in that context, Simcenter provides simulation capabilities to deploy the most appropriate engineering approach to help you achieve the governmental regulations. 


  • How you can deploy an efficient model-based design to address emissions handling using Simcenter Amesim, with Sana Loussaief from Siemens Industry Software.
  • How the Simcenter Amesim library IFP-Exhaust has been coupled with Drive to develop control strategies for the global energy management of a powertrain, with Paul Boucharel from Continental. Our guest speaker presents an efficient way to combine an Electrically Heated Catalyst (EHC) and a 48 V mild-hybrid system. This consists of CO2 emissions optimization study for a given engineering NOx target. A validated model of a diesel exhaust line, including pollutant emissions and temperatures were all used as part of this investigation.
  • How you can go deeper into detailed analysis of a selective catalytic reduction (SCR) with 3D optimization, using Simcenter STAR-CCM+, with Carlo Locci from Siemens Industry Software.
