VGS turbochargers made by ICSI are available in a wide variety of manufactured sizes and cover an engine power range from 25 to 150 kW (per turbocharger). To allow least-cost manufacture and installation, the movable guide-vane mechanism has been designed in a cartridge form. This system is known for its very high reliability and has been optimized further by reducing leakage flows in the latest stage of development.
This means that the entire turbine stage presents a very high efficiency ratio over a wide engine operating range. Bearings with very low friction and highly-efficient compressors also contribute to lower fuel consumption and engine emissions.
