AVL BOOST AVL EXCITE AVL FIRE® Turbocharging / 34 SIMULATION SOLUTIONS Vehicle System Injection Nozzle Flow, Cavitation and Erosion Combustion and Emission Turbocharging Exhaust Gas Aftertreatment Transmission and Driveline Durability and NVH Electrification Thermal Management and Aerodynamics Calibration and Test Quenching TEST SYSTEM SOLUTIONS TESTING EQUIPMENT SIMULATION TOOLS TESTING TOOLS CUSTOMER SERVICES AVL BOOST, AVL EXCITE and AVL FIRE® allow advanced compressor and turbine component design and turbocharger matching as part of an overall engine system. This integrated approach accommodates the complex interaction between the system components in order to create the most effective, low emission engines possible. ENGINE PERFORMANCE AND EMISSIONS CO2 reduction and energy efficiency are the main technology drivers for pressure-charged engines. Turbocharging allows auto manufacturers to reduce their engine sizes and emissions while continuing to deliver the power and performance customers demand. PRESSURE WAVE SUPERCHARGER In contrast to standard pressure charging devices, the pressure wave supercharger process is a direct gas-dynamic transfer of exhaust gas energy to the fresh charge in the channels of the rotor via traveling shock and expansion waves. The underlying physics allow highly predictive 1D modeling where the performance is a simulation result and no maps for mass-flow or efficiency characteristics are necessary. AVL BOOST Model 6 Cylinder Bi-Turbo Ottomotor MULTILEVEL SIMULATION DEPTH Basic thermodynamic matching of the turbocharger is performed for steady-state operation, continued by the optimization of the transient response. The matching calculaton is iterative, based on compressor and turbine maps, as well as the most important engine data. Engines equipped with the charging system can be integrated into the vehicle simulation tool AVL CRUISE, in order to consider the overall system of the engine and vehicle within a driving cycle.
