The structure and function of turbocharger

About 1/3 of the energy generated by the engine burning fuel (internal energy converted from chemical energy-temperature, pressure, gas expansion speed, etc.) is converted into mechanical energy through transmission 1/3 enters the cooling system 1/3 is discharged with exhaust gas.

What the turbochargers do is to convert part of the last 1/3 of the exhaust into the engine intake, to "pre-treat" the gas, thereby saving part of the energy.

The performance of the engine is: the incoming air has already been compressed. A certain temperature and pressure (internal energy increase) is more conducive to fully mixing with the fuel spray in the cylinder, thereby making the combustion more complete, reducing impurities (otherwise the carbon particles and their compounds produced by full combustion) and improving the combustion efficiency

As for the structure of the turbocharger, it is divided into three parts: the compressor intermediate, the turbine housing and bearing housing. The turbine housing is where the engine exhaust gas pushes the steel wheel to do work. The compressor is where the impeller pressurizes the intake air. The intermediate is the connection between the two parts. To fix and load bearing parts, at the same time, the cooling channel of the turbocharger is also in the intermediate The turbocharger component that removes the compressor casing and turbine casing (the air and exhaust gas flow channels are in these two large parts) is called the movement assembly, which is a part assembly after all other parts are installed on the intermediate body. The turbine shaft is a combination of steel turbine wheel and shaft.

In addition, there are several circlips and sealing rings (piston rings) between the intermediate body and the shaft during the installation process.
