Abstract
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.
Claims18
A cylinder head assembly for an internal combustion engine, the assembly comprising:
- a cast cylinder head;
- and
- a charge air cooler (CAC) passage cast into the cylinder head, the cast CAC passage having a first end and an opposite second end,
- wherein the first end is configured to fluidly couple to an outlet of a turbocharger compressor to receive compressed charge air,
- wherein the second end is configured to fluidly couple to a charge air cooler configured to cool the compressed charge air,
- wherein the cast CAC passage comprises:
- a first section extending substantially parallel to a longitudinal axis of the cylinder head;
- a second section extending substantially orthogonal to the longitudinal axis;
- and
- a third section extending substantially orthogonal to both the longitudinal axis and the second section.
The cylinder head assembly of claim, 10 further comprising a bushing received within the actuator bore, wherein the shaft is received with in the actuator bore and coupled thereto for rotational movement.
