Abstract
Embodiments for controlling boost pressure are provided. In one example, a method of controlling a turbocharger of an engine via a multi-staged wastegate comprises during a first condition, actuating a first stage of the wastegate based on boost pressure generated by the turbocharger, and actuating a second stage of the wastegate based on a temperature of a catalyst downstream of the turbocharger. In this way, catalyst heating and boost control may be provided by a common wastegate.
