Multi-Zone Engine Model Feature™

Transportation manufacturers are developing new combustion technologies to meet current and upcoming emissions regulations without performance compromises.  Key attributes such as ignition, flame speed, and pollutant formation are governed by detailed chemistry behavior and the conditions in the cylinder.  Computational Fluid Dynamics (CFD) does not support the level of detailed chemistry required to accurately simulate these combustion performance criteria.  The new Multi-zone engine model allows the segmentation of the cylinder volume into reaction zones where detailed chemistry mechanisms can be applied efficiently while maintaining an accurate representation of the cylinder geometry.

The Multi-zone engine model enables:

• Investigation of ignition and flame speed through a transient solution
• Accurate emissions predictions for NOx, CO and UHC
• Investigation of Exhaust Gas recirculation impacts on the thermal NOx formation rate
