    摘要： A turbocharger system for an engine having a stop/start cycle system is disclosed. The turbocharger system comprises a turbocharger, a conduit and a controller. The turbocharger has a compressor wheel and a turbine wheel connected by a shaft. The conduit is configured to deliver a flow of lubricant to a bearing which supports the shaft. The conduit is provided with a valve. The controller is configured to operate the valve to direct the flow of lubricant through the valve to the bearing during normal operation of the engine, and to substantially stop the flow of lubricant to the bearing when a stop cycle initiation signal is received.

    摘要： A turbocharger (1A) includes a rotary shaft (2), a journal bearing (5A), and a bearing housing (10). The journal bearing (5A) includes load support surfaces (14 and 15), a first gap forming portion (F1), and a second gap forming portion (F2). The first gap forming portion (F1) forms a first gap (101) in a radial direction between the load support surfaces (14 and 15) adjacent to each other in a direction of a central axis (O). The second gap forming portion (F2) forms a second gap (102) smaller than the first gap in the radial direction between the load support surfaces (14 and 15) adjacent to each other in the direction of the central axis (O).
