advanced simulation technologies Simulation Tool-Chain for Turbocharger Analysis Together, AVL BOST, CRUISE, EXCITE and FIRE® provide a full range of investigative simulation tools to improve understanding and aid the development of turbochargers. Turbochargers have become an integral part of the automotive industry’s efforts to enhance existing powertrain and vehicle concepts in order to meet various demands including CO2 emission reduction. AVL’s suite of multi-disciplinary simulation software – BOOST, CRUISE, EXCITE and FIRE® – can offer vital insights for understanding the various physical phenomena taking place in turbochargers. 2 8 F o c u s This article takes a look at some examples. Engine performance and emissions CO2 reduction and a need for improved energy efficiency are the main drivers for charged internal combustion (IC) engines. Turbocharging allows manufacturers to provide downsized engines with high specific power density and, at the same time, to reduce emissions while continuing to deliver the power and performance customers expect. In addition, it is important to optimize the interaction of advanced turbocharging systems with gas exchange and combustion.
