METHOD OF CONTROLLING ASPIRATOR MOTIVE FLOW |
| 摘要 |
Methods and systems are provided for controlling an aspirator shut-off valve in a boosted engine. One example method includes increasing an opening of the aspirator shut-off valve to allow motive flow through an aspirator in response to engine speed between a first, lower speed and a second, higher speed. As such, control of the aspirator shut-off valve may be simplified. |
