[AMESim4.3]Exhaust Gas Aftertreatment系统仿真与优化

Exhaust Gas Aftertreatment

A new product for the AMESim?platform is now being launched by IMAGINE: IFP-Exhaust.

This innovative tool is the result of the partnership signed between IMAGINE and the IFP (Institut Fran鏰is du P閠role) and allows R&D engineers to simulate with high accuracy the complex emissions of exhaust systems.

It offers an open architecture for different analysis and optimization in exhaust gas aftertreatment:

• Load & Regeneration Cycles for DPF Durability
  
• Coupling with Engine Control Strategy
  
• Catalytic Converter Efficiency
  
• Light-off Optimization.
  
• Best location of the catalyst converter
  
• Insulation or engine setting before light-off

Benefits

Thanks to the IFP-Exhaust library, AMESim?makes it possible to consider the chemical reactions resulting from 12 different gas species, taking into consideration all kinetic aspects. Furthermore, the key feature resides in the ready-to-use models of a 3-way catalytic converter, HC trap, Nox trap, oxygen storage, diesel oxidation catalyst, diesel particulate filter, etc. IFP-Exhaust also provides validated components for pipes, volumes, exchangers, sensors & valves to model the after-treatment components right up to the complete exhaust line. A full after-treatment system of the exhaust line is thus defined and enables the analysis of the HC, CO and NOx conversion efficiency.

Key points

• HC, CO and NOx conversion efficiency calculation
  
• Soot Particles Storage
  
• Transient thermal & chemical kinetics
  
• Validation with experiments thanks to IFP expertise
  
• Adapted & state of the art stiff solver for high dynamic stiff kinetic mechanism
  
• Users can add linkage to external kinetic codes, e.g. CHEMKIN
  
• Fully integrated in the AMESim Platform
  
• Electronic Control Unit integration with the Matlab?Simulink?interface
