CHARGE PRESSURE CONTROL METHOD AND DEVICE OF EXHAUST GAS TURBOCHARGER IN INTERNAL COMBUSTION ENGINE

Title:

CHARGE PRESSURE CONTROL METHOD AND DEVICE OF EXHAUST GAS TURBOCHARGER IN INTERNAL COMBUSTION ENGINE

Document Type and Number:

Japanese Patent JP2004011639

Kind Code:

A

Abstract:

To provide a charge pressure control method and the device of at least two compressors and especially an exhaust gas turbocharger capable of evenly distributing load to at least two compressors.

In the charge pressure control method of at least two compressors (6, 8) and especially the exhaust gas turbocharger, a target value (ntus) for output variable of at least two compressors (6, 8) is set as a function of control error in a direction to decrease control error in a first step of charge pressure control. A manipulation variable for adjustment of the target value (ntus) for the output variable and an actual value is formed as a function of difference between a target value (ntus) for output variable and the actual value for the output variable.
