An internal combustion engine includes a cylinder head with an exhaust manifold configured to supply exhaust gas through a main exhaust outlet to a main exhaust aftertreatment system having a main catalytic converter, a bypass passage in fluid communication with the exhaust manifold via a bypass port, a bypass catalytic converter disposed within the bypass passage, and a dual-acting valve assembly configured to move between a first position that seals the bypass port, and a second position that seals the main exhaust outlet. During cold start, long idle, and/or low main catalytic converter temperature conditions, the dual-active valve assembly is moved to the second position to direct exhaust flow through the bypass passage and the bypass catalytic converter to reduce emissions.

A cylinder head assembly for an internal combustion engine includes a cast cylinder head, a turbocharger housing integrally cast with the cylinder head, and a water jacket cast into the integrally cast turbocharger housing and configured to receive a flow of coolant for cooling the integrally cast turbocharger housing. The assembly can also include a wastegate housing integrally cast with the cylinder head and the turbocharger housing, and a water jacket cast into the integrally cast wastegate housing. The water jacket is configured to receive a flow of coolant for cooling the integrally cast turbocharger housing and the integrally cast wastegate housing.

Cylinder head with integrated turbocharger

A cylinder head assembly for an internal combustion engine includes a cast cylinder head, a turbocharger housing including a compressor housing and turbine housing integrally cast with the cylinder head, and a turbocharger cartridge assembly configured to be inserted into the turbocharger housing and including a shaft coupled between a compressor wheel and a turbine wheel. A compressor cover is configured to couple to the compressor housing and define a compressor inlet and at least partially define a compressor diffuser passage. The cartridge assembly includes a housing having a diffuser flange extending outwardly therefrom, the diffuser flange including a front surface and an opposite contoured volute surface. The compressor diffuser passage is at least partially defined by the compressor cover and the diffuser flange front surface. A compressor volute is at least partially defined by the diffuser flange contoured volute surface and a contoured inner surface of the compressor housing.

A cylinder head assembly includes a cast cylinder head and a turbocharger housing integrally cast with the cylinder head. The integrated cylinder head and turbocharger housing includes: (i) a compact low wetted area to provide an uninterrupted flow path pointed directly at a catalyst face to facilitate achieving cold start emissions targets, (ii) a casting core assembly with specific core geometry and steps for assembly to enable core assembly while meeting all cylinder head and integrated turbine housing functional requirements, (iii) an oxygen sensor disposed pre-turbine in an integrated exhaust manifold, and (iv) a fully integrated PCV make-up air system.

A cylinder head assembly for an internal combustion engine includes a cast cylinder head and a turbocharger housing integrally cast with the cylinder head and having an integrally cast wastegate housing. The turbocharger housing is configured to receive a turbocharger cartridge rotatably supporting a shaft coupled between a compressor wheel and a turbine wheel. The integrally cast wastegate housing defines a wastegate chamber configured to receive a wastegate valve, a flow of exhaust gas from the turbine wheel, and a flow of wastegate exhaust gas.

A cylinder head assembly for an internal combustion engine includes a cast cylinder head having at least one oil gallery, a turbocharger housing integrally cast with the cylinder head, and a turbocharger cartridge assembly configured to be inserted into the turbocharger housing and including at least one bearing rotatably supporting a shaft coupled between a compressor wheel and a turbine wheel. A lubricant passage is formed within the turbocharger housing and configured to supply oil from the at least one oil gallery to the turbocharger cartridge assembly to lubricate the at least one bearing. A seal assembly is disposed at least partially within the turbocharger housing to receive lubricant from the lubricant passage and includes a sealing end configured to seal against the turbocharger cartridge assembly.

Ozone generator

An air induction system for a vehicle includes a turbocharger having a compressor side inlet and a bifurcated clean air intake system having a bifurcated conduit. The bifurcated conduit includes an upstream end configured to receive intake air, a downstream end configured to supply intake air to the compressor side inlet, an inner passage configured to supply intake air to the downstream end, and an outer passage disposed about the inner passage and separated from the inner passage by an inner wall, the outer passage configured to selectively receive recirculation backflow from the compressor side inlet. A port is fluidly coupled between the outer passage and another location of the vehicle. The port is configured to selectively evacuate at least a portion of the recirculation backflow to the another location the vehicle.

A turbocompressor boost purge ejector tee includes a first passage formed into a housing along a common axis from a first direction, the first passage including an outlet in communication with an inlet area of the turbocompressor. A second passage is formed into the housing along the common axis from a second direction and includes a boost air inlet in communication with a turbocompressor high pressure internal outlet area and fluidly coupled to the first passage. The first and second passages of the housing defining a first flow path from the internal outlet area to the inlet area. An inlet port is associated with the housing and intersects the first passage, the housing defining a second flow path from the inlet port to the outlet, and the second flow path intersecting the first flow path upstream of the outlet. A nozzle is positioned in the second passage.

Integral purge ejector tee arrangement in a turbocompressor

A boost purge ejector tee arrangement is integrated into a turbocompressor associated with an engine and includes first and second passages, an inlet port and a nozzle. The first passage is formed into a housing of the turbocompressor and includes an outlet in communication with a turbocompressor inlet. The second passage is formed into the housing and includes a boost air inlet in communication with an internal outlet area of the turbocompressor and intersecting the first passage. The inlet port is associated with the housing and intersects the first passage. The nozzle is positioned in the first passage such that an outlet of the nozzle is proximate the intersection of the inlet port and first passage. During a boost mode of operation, the second passage is adapted to receive boost air flow, which flows through the nozzle thereby creating a vacuum and drawing purge through the inlet port.
