A turbocharger for an internal combustion engine is provided. The turbocharger includes at least three connections for respective lines. The at least three connections are arranged on the same side of the turbocharger. The turbocharger is designed in such a manner that the lines can be mounted with a common screw to the at least three connections.

Systems are provided for a combined compressor-cooling unit for an intake system. In one example, the system includes a housing, with a compressor, a liquid cooling system, a filter, and an air intake arranged within the housing such that the filter encases the compressor at least in part.

The present invention relates to an improved turbocharger assembly, particularly of the variable geometry type. The improved turbocharge assembly contains a turbine. The turbine includes an impeller housed in a casing, a flange that can be sealingly associated with a corresponding flange of an exhaust gas manifold of an engine, and a clapet valve that contains a shutter element and a housing seat. The housing seat is fashioned in a frame made in one piece with the casing.

An e-charger includes a motor case that encases the motor and an outer housing that houses the motor case. The e-charger additionally includes a cooling system with passages cooperatively defined by the outer housing and the motor case. First and second longitudinal passages extend between the first and second ends of the motor, and a second longitudinal passage extends between the second and first ends of the motor. The end passage fluidly connects the first and second longitudinal passage. The cooling system is configured for directing flow of the coolant from the inlet, through the first longitudinal passage in a first longitudinal direction with respect to the axis, through the end passage, and back through the second longitudinal passage in a second longitudinal direction with respect to the axis.

An exhaust turbocharger has a housing, in which a shaft is mounted by bearings, which carries a turbine wheel, on the one hand, and a compressor wheel, on the other hand. An electric machine has a rotor and a stator. The rotor is secured on the shaft for conjoint rotation therewith and the stator surrounds the rotor radially on the outside. A sleeve, which supports the rotor radially and axially, is arranged between the stator and the rotor. The sleeve has at least one fluid duct, by way of which a cooling fluid can be guided toward the bearings of the shaft.

A centrifugal compressor includes: a housing; an impeller rotatably disposed within the housing; a rotational shaft connected to the impeller; and a bearing member supporting the rotational shaft in the housing. An oil flow passage through which oil flows is formed in the housing. The oil flow passage includes a lubricating oil passage through which the oil flows as lubricating oil to be supplied to the bearing member, and a cooling oil passage through which the oil flows as cooling oil for heat exchange with a fluid compressed by the impeller. The cooling oil passage is configured so that the oil flows into the cooling oil passage as the cooling oil without passing through the bearing member.

The invention is a device (1) for cooling a power electronic system (EP) comprising at least one power electronic component (2) mounted on at least one circuit board (3), the cooling device (1) comprises a hose (4) for circulating a flow (5) at an ambient temperature. The cooling device (1) comprises a first heat exchange surface (6) that is thermally connected to the power electronic components (2) and at least one second heat exchange surface (7). The second heat exchange surface (7) is for heat exchange with the flow (5) circulating through the hose. The second heat exchange surface (7) is fitted inside the circulation hose (4) to remove heat by convection with the circulating flow (5). The second heat exchange surface (7) is thermally connected to the first heat exchange surface (6).

Various systems are provided for an axially split turbocharger case housing each of a turbine of a turbocharger, a compressor of the turbocharger, and a bearing of the turbocharger. In one example, an apparatus for an engine includes a first monolithic component and a second monolithic component that, when coupled together, form a turbocharger case configured to house each of a turbine, a compressor, and a bearing, the first and second monolithic components, when coupled together, also forming a compressor shroud and a turbine shroud. In further examples of the system, portions of the turbocharger case are formed of a lattice structure.

Various systems and methods are provided for a shroud of a turbomachine. In one example, a turbomachine includes a case and a rotor rotatably coupled to the case and configured to transfer energy between the rotor and a working fluid. The case includes a shroud housing the rotor, the shroud including an inner shell, an outer shell, and a lattice structure positioned between the inner shell and the outer shell.

An e-charger includes a shaft supported for rotation about an axis. The e-charger also includes a compressor wheel that is attached to the shaft. The e-charger further includes an electric motor configured to drive the shaft and the compressor wheel in rotation. Also, the e-charger includes a housing that houses the electric motor and at least part of the shaft. Moreover, the e-charger includes a dampening system incorporated in the housing and configured to dampen loads transferring through the housing. The dampening system includes at least one solid-state dampener that is resiliently flexible, and the dampening system includes at least one fluid viscous dampener.
