AVL BOOST, CRUISE M, F IREM

Exhaust gas aftertreatment simulation suite

AVL offers a comprehensive portfolio of thermo-chemical simulation models

Concept definitionAVL 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 levelAVL 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 strategiesAVL 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 testingThe 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

AVL’s simulation suite can be applied throughout the entire development process

• Concept study and design layout• Calibration and control development• Issue resolution as DPF cracking, catalyst deactivation, urea crystallization, performance degradation• System integration taking into account influence of complete vehicle and real-world environment
