Abstract: A turbocharger is provided herein. The turbocharger includes a housing and an adjustable core at least partially circumferentially surrounded by the housing, the adjustable core having a turbine rotor coupled to a compressor rotor via a shaft. The turbocharger further includes an adjustment mechanism coupled to the adjustable core configured to adjust an axial position of the housing relative to the adjustable core in response to adjustment commands.

Abstract: An EGR mixer comprises an upstream conduit section having a contracting flow area in a direction of air flow through the mixer, a downstream conduit section having an expanding flow area in the direction of air flow through the mixer, a slot formed in the downstream conduit section for admitting exhaust to the air flow, and an abrupt flow-expanding ridge disposed between the upstream and downstream conduit sections. With the EGR mixer configured in this manner, recirculated exhaust may be effectively homogenized into an intake air flow with reduced drag.

Abstract: An internal combustion engine system having a turbocharger having compressor driven by a turbine through a common shaft is disclosed. An acoustic sensor is displaced from the compressor and positioned relative to the compressor to detect sound waves emitted by the compressor during rotation of the compressor about the common shaft by the turbine and for producing an electrical signal in response to such detected sound waves. A processor is responsive to the produced electrical signal for controlling operation of the engine system during operation of such engine system.

Abstract: A charge air conditioning system, including a charge air booster, a refrigerant-to-air intercooler which is integral with the charge air booster, and a refrigeration system for supplying refrigerant to the refrigerant-to-air intercooler.

Abstract: An automotive engine has a charge air conditioning system, including a charge booster, and a first intercooler for transferring heat from charge air flowing from the booster. The first intercooler transfers heat from the charge air to ambient air, and a second intercooler downstream from the first intercooler further reduces the heat content of the charge air by transferring heat from the charge air to a refrigerated fluid. An engine control module controls the engine's spark timing and fuel charge as a function of at least the amount of air charge cooling provided by the second intercooler. The present engine is particularly well adapted to operate on gaseous hydrogen fuel.

Abstract: A charge air management system for an automotive engine provides air charge densification and cooling during periods of operation at higher load. Two air ducts are provided, with a first for furnishing uncooled and unboosted air, and with a second duct for furnishing chilled and boosted air, with the second duct being chilled during operation with air flowing through the first duct.
