| 发明名称 | Multi-staged wastegate | ||
| 摘要 | 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. | ||

| 主权项 | 1. A method of controlling a turbocharger of an engine via a multi-staged wastegate, comprising: during a first condition, actuating a first stage of the wastegate based on boost pressure generated by the turbocharger;actuating a second stage of the wastegate based on a temperature of a catalyst downstream of the turbocharger, the first stage of the wastegate regulating an opening positioned within the second stage of the wastegate; andactuating a compressor bypass valve concurrent with the actuating of the second stage of the wastegate. | ||
