Internal combustion engine supercharging controlling method for motor vehicle, involves regulating supercharging pressure around set point value and further regulating pressure from values of rotation speed of turbocharger

摘要

#CMT# #/CMT# The method involves regulating supercharging pressure around a set point value developed from state variables comprising air pressure (Pavc) in upstream of a turbocharger (14) of an internal combustion engine (10). The supercharging pressure is further regulated from values (Ncomp) of rotation speed of the turbocharger, where the values of the rotation speed are utilized for developing a maximal value of pressure in downstream of the turbocharger. #CMT# : #/CMT# An independent claim is also included for a system for controlling the supercharging of an internal combustion engine of a motor vehicle. #CMT#USE : #/CMT# Used for controlling the supercharging of an internal combustion engine of a motor vehicle (claimed). #CMT#ADVANTAGE : #/CMT# The supercharging pressure is regulated from the measurement of the rotation speed of the turbocharger, thus permitting to efficiently regulate the pressure of the air admitted in an intake manifold of the engine while permitting to rapidly detect the malfunction of the turbocharger in improved manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a general structure of an internal combustion engine of a motor vehicle provided with a control system.
