Method for controlling a turbocharger system of an internal combustion engine, and turbocharger system

摘要

The disclosure relates to a method for controlling a turbocharger system of an internal combustion engine. The method comprises controlling a first bypass valve of a high pressure exhaust gas turbine and a second bypass valve of a low pressure gas turbine on the basis of a turbine model, the first and second bypass valves continuously variable. In this way, turbocharger system efficiency may be maximized.

主权项

1. A method for controlling a turbocharger system of an internal combustion engine, comprising:
controlling a first bypass valve of a high pressure exhaust gas turbine and a second bypass valve of a low pressure gas turbine based on a turbine model, the model determining set positions of the first and second bypass valves, and the first and second bypass valves continuously variable; and adjusting one of the first or second bypass valve while maintaining the set position of the other of the first or second bypass valve to maintain charge pressure and engine load.
