Abstract: A supercharged internal combustion engine has a supercharger operable to selectively supply a mass of air from below through above atmospheric air pressure according to the operating requirements of the engine. The supercharger has a shuttle combined with a throttle valve that controls the mass of air directed to an air mass bypass opening and supplied to the internal combustion engine. The shuttle has rollers that ride on rails that allow the shuttle to move to open and close the air mass bypass opening in communication with a casing that directs a mass of atmospheric air and a bypass mass of air interfused with the mass of atmospheric air to an air mass inlet of the supercharger.

Abstract: An exhaust turbine power generating system includes an internal combustion engine, an exhaust turbine power generator, and an electronic control unit configured to individually control a first electric power generation load of the exhaust turbine power generator in a first period and a second electric power generation load of the exhaust turbine power generator in a second period and to perform control such that the second electric power generation load of the exhaust turbine power generator becomes equal to or smaller than the first electric power generation load. The first period is a period that starts at an exhaust start timing in an exhaust cycle and the second period is a period after the first period in the exhaust cycle. The exhaust start timing is a timing at which the exhaust gas starts to be discharged toward the turbine from an arbitrary cylinder in the internal combustion engine.

Abstract: A compressor recirculation valve having features for mitigating the “rush” noise caused when the valve opens and compressed recirculation air rushes through the valve into the compressor inlet. The features for mitigating rush noise include a generally annular wall that projects from the valve seat and surrounds the valve member. The radially inner surface of the wall can be conical and can include radially inwardly projecting teeth between which are V-shaped grooves.

Abstract: A turbocharger system for an engine includes a rotor, a primary bearing system arranged to axially and radially support the rotor to rotate on a central rotational axis, a compressor coupled to a rotor to rotate with the rotor, a turbine coupled to the rotor to rotate with the rotor, and an electromagnetic actuator adjacent to the rotor. The electromagnetic actuator selectively acts on the rotor and supplements the axial support of the primary bearing system by applying a magnetic force on the rotor in a direction parallel to the central rotational axis of the rotor.

Abstract: In a method for monitoring a rotation of a compressor wheel of an exhaust-gas turbocharger, which compressor wheel has on the peripheral side a number n of blades, an inductive sensor is provided for detecting the speed or rotational frequency, which sensor produces at least one output signal as a function of eddy currents generated as the blades pass by, and the rotational speed of the compressor wheel is inferred from a fundamental frequency of the output signal. In addition, information about a fault of the compressor wheel is derived from at least one modulation of the output signal, e.g., amplitude modulation, and an imbalance of the compressor wheel is detected.

Abstract: A method and apparatus for protecting downstream engine components from damage in the event of a turbine failure involves positioning a debris trap downstream of a turbo and upstream of an engine. The debris trap includes an outer body with an inlet opening at a first end of a first diameter, an outlet opening, and an interior of a second diameter which is larger than the inlet opening. An inner body extends into the interior of the outer body with air flow openings in the inner body communicating with the outlet opening. An impaction plate is supported by the inner body in axial alignment with the inlet opening. Turbo fragments strike and are slowed by impact with the impaction plate. The turbo fragments collect in the interior of the outer body with air escaping by entering the air flow openings of the inner body and passing to the outlet opening.

Abstract: A nozzle assembly of a turbocharger includes a nozzle and a ring-shaped body. The nozzle has flow passages extending through the nozzle and configured to direct air received from a volute housing of the turbocharger through the nozzle to turbine blades of the turbocharger. The ring-shaped body is coupled with the nozzle and is configured to rotate around the nozzle. The ring-shaped body includes blocking segments that block the flow of the air and openings between the blocking segments that permit the air to flow through the ring-shaped body. The ring-shaped body is configured to rotate relative to the nozzle to change how many of the flow passages in the nozzle are blocked by the blocking segments of the ring-shaped body.

Abstract: A process for monitoring turbocharger operation in a machine is disclosed. The machine includes a power source having an intake manifold for supplying the power source with air and a plurality of turbochargers. Each turbocharger includes an air inlet passageway to receive air, a plurality of pressure sensors arranged within the inlet passageway, a compressor configured to pressurize air, an air outlet passageway to direct pressurized air from the compressor to the intake manifold, and an exhaust turbine operably driven by exhaust gas from the power source and coupled to the compressor by a turbine shaft. The process includes monitoring the differential pressure across the air inlet passageway for each turbocharger, comparing the differential pressures for each turbocharger and indicating an anomaly in turbocharger speed when the differential pressure for one turbocharger exceeds the differential pressure for another turbocharger by a threshold amount.
