Abstract
Embodiments for an engine coupled to a first turbocharger and a second turbocharger are provided. One example includes responsive to a first condition, deactivating a first turbine of the first turbocharger and meeting a boost demand via operation of the second turbocharger, and responsive to deactivating the first turbine, increasing a pressure at a compressor-side end of a bearing arrangement of a shaft of the first turbocharger. In this way, oil leakage from the bearing arrangement may be reduced.
