VERFAHREN UND VORRICHTUNG ZUR LUFTAUFLADUNGSEGELUNG EINES VERBRENNUNGSMOTORS

摘要

The method involves regulating a pressure in an intake manifold (18) of an internal combustion engine (10) around a set point value of a supercharging pressure. A pressure in upstream of a turbine (26) is adjusted so that the pressure in upstream of the turbine exceeds a predetermined threshold value. The set point value is elaborated based on speed of the engine and fuel flow rate and is corrected based on an ambient parameter such as atmospheric temperature and pressure. An independent claim is also included for a device for controlling supercharging of air to an internal combustion engine of a motor vehicle.
