Maybe you have ever heard about turbo( turbocharger), and also know some basic situations about it. But do you know about the internal component of turbo? If not, this article will help you to understand it much better.
The key components of turbo includes the turbine, the compressor and the hub rotating assembly three main parts. And of course many turbocharger installations use additional technologies, such as wastegates, intercooling and blow-off valves.
The turbo turbine housing direct the gas flow through the turbine as it spins at up to 250,000 rpm. The size and shape can dictate some performance characteristics of the overall turbocharger. Often the same basic turbocharger assembly is available from the manufacturer with multiple housing choices for the turbine, and sometimes the compressor cover as well. This lets the balance between performance, response, and efficiency be tailored to the application.
The turbo compressor housing increases the mass of intake air entering the combustion chamber. The compressor is made up of an impeller, a diffuser and a volute housing.
The center hub rotating assembly (CHRA) houses the shaft that connects the compressor impeller and turbine. It also must contain a bearing system to suspend the shaft, allowing it to rotate at very high speed with minimal friction.
