Variable geometry supercharger controlling system i.e. electronic control unit, for internal combustion engine i.e. diesel engine, of motor vehicle, has calculating block deducing set point of geometry of compressor to regulate geometry

摘要

The system i.e. electronic control unit (3), has a regulation device (31) for regulating supercharging pressure by acting upon variable geometry of a variable geometry turbine (15). A regulation device (43) regulates variable geometry of a variable geometry compressor (14). A determining device has a corrector for determining the rate and ratio of compression of the compressor. The determining device has a calculating block (34) with a memorized cartography for deducing set point of the variable geometry of the compressor for regulating the variable geometry of the compressor. An independent claim is also included for a method for controlling a supercharger of an internal combustion engine of a motor vehicle.
