powertrain engineering Virtual Test 1 2 F O C U S cesses are more and more transferred to the virtual world. AVL’s IODP (Integrated and Open Development Platform) allows the transfer of specific emissions solutions into simulation environments in early development phases. This enables engineers to combine real with virtual tests,” Fraidl explains. RDE AND SULEV SOLUTIONS FOR DIESEL AND GASOLINE ENGINES Since diesel vehicles play a significant role in meeting CO2 fleet targets, AVL offers wide-ranging expert knowledge in the field of emissions optimization for diesel vehicles, which is available throughout the entire AVL network. The engineering services encompass the complete range of development – from the early concept definition to series development and support in production ramp-up. Key element in this regard is a model-based simulation environment with a semithe particle number (PN) in vehicle emissions under real driving conditions. The AVL M.O.V.E Exhaust Flow Meter measures the exhaust emission mass flow. For a quick integration, evaluation and consolidation of the collected data, AVL CONCERTO PEMS software is available. The reliable measurement solution is perfectly suitable for the combined calibration of fuel consumption, emissions and driveability, and can be easily mounted on the tow bar. “AVL offers the entire measurement chain, which is needed for an efficient RDE development. And there’s even more: Since RDE cycles need to be driven under most diverse conditions, purely experimental development and validation in these very short development times simply aren’t possible. Therefore, such development pro- physical background. This simulation environment allows engineers to identify the interaction between the combustion concept, aftertreatment system and powertrain in an early phase, and to define and implement a product which is both stable in terms of emissions and optimal regarding CO2. “AVL also offers similar approaches for gasoline engines. With these approaches engineers can develop robust and, above all, efficient emissions solutions. In this field, AVL’s competitive advantage lies in its comprehensive fundamental knowledge as well as in its proven and validated development methods concerning the reduction of pollutant raw emissions and optimization of exhaust gas aftertreatment systems, particularly the effective application of particle filters in gasoline engines”, Fraidl added.
