AVL BOOST, CRUISE M, FIRE M Exhaust gas aftertreatment simulation suite AVL offers a comprehensive portfolio of thermo-chemical simulation models Concept definition AVL BOOST: 1D fluid and thermo-chemistry; Fast and easy • Kinetics parameter identification • Prediction of light off and conversion efficiency • Soot loading and regeneration strategies • Brick volume, catalytic coating, urea dosing’ Investigation on component level AVL FIRE: 3D CFD; Detailed design assessment • Influence of flow uniformity on catalytic reactions, soot loading and regeneration • Urea injection and mixing strategies, gas phase and catalytic reactions • Thermal load on monolith, housing and pipes Vehicle control strategies AVL CRUISE M: Multi-physics system simulation • Realtime Engine, Drivetrain and Flow system simula- tion to predict vehicle emissions during driving cycles • Aftertreatment control strategies combined with other control strategies e.g in HEV concepts • Assessment of complete vehicle system and driver behavior influence on aftertreatment system perfor- mance Effective testing The use of simulation tools reduces the number of pro- totypes required. Multiple load points and applications are investigated and endurance testing is performed. Testing tools used by our engineers are: • AVL CAMEO • AVL SESAM FTIR • AVL PLUreaTM The challenge: Emission regulations are becoming increasingly stringent and difficult to meet. Development cycles are getting shorter and budgets are reduced while reliability and efficiency have to be ensured. The solution: Utilizing the industries most advanced development tools combined with the expertise and experience of our skilled engineers enables delivering solutions that satisfy both standards and constraints
