Abstract: A turbocharger for an internal combustion engine includes a bearing housing with a bearing bore and a semi-floating bearing disposed within the bore. The turbocharger also includes a shaft having a first end and a second end, wherein the shaft is supported by the bearing for rotation about an axis within the bore. The turbocharger also includes a turbine wheel fixed to the shaft proximate to the first end and configured to be rotated about the axis by post-combustion gasses emitted by the engine. Additionally, the turbocharger includes a compressor wheel fixed to the shaft proximate to the second end and configured to pressurize an airflow being received from the ambient for delivery to the engine. Furthermore, the turbocharger includes a plate secured within the bearing housing and configured to prevent rotation of the bearing about the axis. An internal combustion engine employing such a turbocharger is also disclosed.

Abstract: A vehicle includes an intercooler cooling fluid circuit coupled to and in fluid communication with a turbocharger of an internal combustion engine for circulating a flow of cooling fluid to the turbocharger to cool the turbocharger. A turbocharger cooling control valve controls fluid flow between the turbocharger and an intercooler. The turbocharger cooling control valve directs the flow of the cooling fluid to the intercooler when the engine is running, directs the flow of cooling fluid to the turbocharger when the engine is not running. The vehicle uses an intercooler pump for circulating the cooling fluid to both the intercooler when the vehicle is running and the turbocharger when the vehicle is not running.

Abstract: There are provided first and second water supply passages to supply cooling water from an engine to first and second center housings of first and second turbochargers, and first and second return passages to return the cooling water from the first and second turbochargers to the engine. A cooling-water connection portion of the first water supply is located above the level of a cooling-water connection portion of the second water supply passage. A vapor releasing passage is provided between the second turbocharger and an upper tank provided on the outside of an engine body at a position located above the connection portion of the second return passage of the second turbocharger. Accordingly, the function of vapor releasing from the first and second turbochargers can be improved, thereby increasing the layout flexibility around the engine.

Abstract: A valve arrangement for venting a coolant circuit of an internal combustion engine having several subcircuits includes a valve which is in fluid communication with a primary vent line extending from one of the subcircuits. At least one secondary vent line is in fluid communication with the valve and extends from another one of the subcircuits. The primary and secondary vent lines are connectable to a shared third vent line which feeds into a compensating reservoir arranged at a geodetically highest point in the coolant circuit. The valve is constructed to establish a continuous fluid communication of the primary vent line with the compensating reservoir via the third vent line and to establish a fluid communication of the secondary vent line with the compensating reservoir via the third vent line only in the presence of air bubbles in the secondary vent line.
