What is a turbocharger in its essence?
A turbocharger is an element consisting of many details and more precisely, it is a system through which to increase the power of an internal combustion engine. A turbocharger is composed of a turbine and a compressor part, which are quite similar but actually have different functions, in essence they are two blades (turbine blade and compressor blade) connected by the working shaft/axis, which is constantly lubricated with oil and is supported. The exhaust gases that exit and are generated by the engine pass through the turbine part and rotate the turbine blade, which in turn rotates the compressor blade. In this way, the compressor blade sucks in air, which compresses/thickens and then pumps it to the engine under a certain pressure according to the set settings and parameters. With this method, through more air, the engine can burn more fuel more fully and the Fuel-Air mixture can be changed and optimized, and from there increase power.
Here you can actually see the entire turbo system: air intake, compression, flow of the intake and compressed air through the intercooler to the engine, the exhaust gas outlet from the engine to the turbocharger, and how the gases and air move:
