Development of Advanced Turbocharging Systems
One of the key technologies for future Diesel and gasoline engines will be concepts based on advanced boosting systems. Downsized S.I.-engines will be charged, especially in combination with direct injection, to combine their fuel saving potential with driving fun. With regard to Diesel engines, the trend towards higher specific power outputs lead to an increasing need for charging systems, which can provide sufficient boost pressure over a wide engine speed range at full load. More stringent emission regulations will lead to increased EGR-rates at higher speeds and loads than today, also requiring new charging concepts. In today's powertrain research and development, only strong cooperation between testing and CAE leads to competitive products, this is especially true for boosting technology. FEV therefore has developed a number of tools and methods for integrated development e.g. in the following working areas: - thermodynamic layout; - design, packaging and vehicle integration; - flow design; and - thermomechanical fatigue and durability.
