SYSTEM AND METHOD FOR GAS PURGE CONTROL |
| 摘要 |
Systems and methods for providing vacuum to one or more of a crankcase ventilation system, an emission control system, and an exhaust gas recirculation (EGR) system included in a turbocharged engine system are provided. In one example, approach, a method comprises drawing vacuum from a vacuum source located in an intake of the engine downstream of a pre-compressor throttle and upstream of an intake throttle, and applying the drawn vacuum to a discharge outlet of a uni-directional crankcase ventilation system, where an inlet of the crankcase ventilation system is coupled to the intake of the engine upstream of the pre-compressor throttle. |

1. A method for a turbocharged engine, comprising:
drawing vacuum from a vacuum source located in an intake of the engine downstream of a pre-compressor throttle and upstream of an intake throttle; applying the drawn vacuum to a discharge outlet of a uni-directional crankcase ventilation system, where an inlet of the crankcase ventilation system is coupled to the intake of the engine upstream of the pre-compressor throttle. |
