An internal combustion engine includes an exhaust conduit having an exhaust port fluidically coupled to ambient fluid and having an internal cross-sectional area and an engine cylinder fluidically coupled to the exhaust conduit. A fluidic amplifier is disposed within the exhaust conduit and is fluidically coupled to the engine cylinder. The amplifier is further fluidically coupled to a source of primary fluid and is configured to introduce the primary fluid and at least a portion of fluid from the engine cylinder to the exhaust port.

Methods and systems are provided for a resonator of an exhaust system. In one example, the resonator is a quarter wave resonator with a diaphragm configured to provide pulsations during low-end engine torque conditions.

A turbine assembly includes a turbine casing, a turbine wheel, vanes, and link plates. The turbine casing defines a center chamber and a volute configured to transport exhaust gas to the center chamber. The turbine wheel is disposed within the center chamber and is rotatably coupled to the turbine casing. The driving ring extends around a periphery of the center chamber and is rotatably coupled to the turbine casing. The vanes are disposed within the center chamber and are configured to adjust a flow rate of exhaust gas from the volute to the turbine wheel. The link plates couple the vanes to the driving ring such that the vanes pivot when the driving ring rotates. When the ring is rotated to a given position, the link plates are configured to pivot one of the vanes to one position while pivoting another one of the vanes to another position.

A turbocharger for an engine includes a housing, a shaft, a turbine wheel mounted to the shaft for rotation therewith, a compressor wheel mounted to the shaft for rotation therewith, and a bearing cartridge rotatably supporting the shaft relative to the housing. The housing is positioned axially between the turbine and compressor wheels. The bearing cartridge includes an inner ring mounted to the shaft, an outer ring disposed between the inner ring and the housing and movable relative to the housing, and a first and a second plurality of roller elements axially spaced apart from one another and disposed radially between the inner and outer rings to rotatably support the inner ring relative to the outer ring. A radial gap (RD) is defined between the outer ring (134) and the housing (126). Lubricant flows into the radial gap and radially separates the outer ring from the housing during operation of the turbocharger.

A heating system is configured to produce heated fluid. The system includes a source of primary fluid, a diffusing structure comprising an outlet structure out of which the heated fluid flows, at least one conduit coupled to the source and the diffusing structure and configured to introduce to the diffusing structure the primary fluid, and an intake structure coupled to the diffusing structure and configured to introduce to the diffusing structure a secondary fluid accessible to the system. The heated fluid includes the primary and secondary fluids.
