Description

Technical Field

[0001] The utility model relates to the technical field of turbochargers, in particular to a turbine shell mounting structure and a turbocharger. Background Art

[0002] Gasoline engines generate power through combustion of a combustible mixture of gasoline and air within the cylinder. The power and torque of an electronic fuel injection gasoline engine depend on the amount of air entering the cylinder. When the engine is already operating at its optimal performance, the only way to increase its output power is to compress more air into the cylinder to increase the amount of combustible mixture, thereby improving combustion and output power. A turbocharger is a control device that uses pressure to drive the pump impeller in the housing to rotate, thereby driving the turbine impeller in the intake plenum chamber to pressurize air into the cylinder, thereby increasing engine output power.

[0003] The turbine housing is a key component connecting the turbocharger to the engine's exhaust system. One end connects to the engine's exhaust manifold, allowing exhaust gases to flow smoothly from the engine to the turbocharger. The other end connects to the exhaust duct, which discharges exhaust gases after passing through the turbine to the outside world. This connection enables the entire exhaust system to work together, ensuring a smooth exhaust process. It also provides positioning and support for the turbocharger's installation within the engine compartment, ensuring accurate relative positioning between the turbocharger and the engine and other components.

[0004] The existing turbine housing has a relatively complex mounting structure and is cumbersome to install. After being connected to other components, there is a problem of insufficient stability of the mounting structure. Utility Model Content
