Embodiment Construction

[0037] Described herein are systems and methods for integrally casting features or components into cylinder heads of internal combustion engines. Typically, internal combustion engines are compact assemblies of hardware that often need to fit into very tight engine compartment spaces. When components with high mass and density, such as a turbocharger system, are bolted to the outside of the engine, the resulting structure can affect NVH (Noise Vibration and Harshness), dynamics, Packaging, decoration, durability, etc.

[0038] In order to reduce or prevent such problems in the present disclosure, the turbocharger housing is integrated (eg, cast) into an aluminum cylinder head, which is advantageously configured to reduce engine cost, improve packaging, simplify assembly, reduce assembly steps The number of catalyst light removal, reduce turbocharger noise (such as wastegate resonance, flow noise, rotor set unbalanced whistle, etc.), improve engine warm-up and improve fuel eco...

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 waste gate 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 waste gate housing defines a waste gate chamber configured to receive a waste gate valve, a flow of exhaust gas from the turbine wheel, and a flow of waste gate exhaust gas.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 62841916, filed May 2, 2019, the contents of which are incorporated herein by reference in their entirety. technical field [0003] The present application relates generally to internal combustion engines with turbochargers, and more particularly to internal combustion engines with cylinder heads with integrated turbochargers. Background technique [0004] Turbocharger systems typically represent a significant portion of an engine's cost. In addition, typical gasoline engine turbine casings have significant amounts of nickel and chromium, thereby accounting for a significant portion of the cost of the turbocharger. Additionally, gaskets, fasteners, fittings, pipes, and other turbocharger-related components often need to be made of high-quality materials due to, for example, the heat, pressure, and vibrations induced by the turbocharger. W...
