Load Control: Notes
Load control of the N63 engine is realized by means of the throttle valve and the wastegate valves.
The throttle valve is the primary component in this process. The wastegate valves are actuated to bring about a fine tuning of the boost pressure. At full load the throttle valve is completely open and load control is undertaken by the wastegate valves.
The load control graphic shows that the wastegate valves are integrated in load control in all operating situations of the N63 engine on the basis of characteristic map control.
