Arrangement controlling the output pressure of a turbocharger for an internal combustion engine
First Claim
1. A control arrangement for the output pressure of a turbocharger for an internal combustion engine comprising a servo element to control the operation of the turbocharger and control means to actuate the servo element in accordance with at least the speed of the engine wherein the control means includes at least one target diagram for providing turbocharger output pressure target data based on an engine operating parameter and means for reading out target data from the target diagram of the control means to control the turbocharger output pressure when the engine is operating in a first engine load range, and a turbocharger output pressure controller for controlling the turbocharger output pressure when the engine is operating in a second engine load range including means for providing a pre-control based on target data read out of the target diagram.

Abstract
A control arrangement for a turbocharger for an internal combustion engine with a variable turbine geometry which includes a control unit for controlling a turbocharger output pressure according to engine operating parameters when the engine is operating in a first engine load range with regulated exhaust gas return and a pressure controller for controlling the turbocharger output pressure when the engine is operating in a second engine load range with the exhaust gas return switched off including allowance for a precontrol by the control unit.
