| 发明名称 | Method and system for exhaust gas recirculation | ||
| 摘要 | Methods and systems are provided for an engine including a first turbocharger having a first compressor and a second turbocharger having a second compressor. An EGR differential between the first compressor and the second compressor may be increased under a condensation condition, and decreased under a surge condition. The EGR differential may also be decreased when a compressor outlet temperature exceeds an outlet temperature threshold. | ||

| 主权项 | 1. A method of operating a twin-turbocharger engine, comprising: increasing an EGR flow differential between EGR flow to a first compressor and to a second compressor via closing a cross-over valve responsive to an intake temperature that corresponds with condensation accumulation; and decreasing the EGR flow differential between EGR flow to the first and to the second compressor via opening the cross-over valve responsive to a surge condition. | ||
