What is a turbocharger?
As we know, a turbocharger is actually a type of supercharger. A turbocharger is a turbine-driven forced induction device that increases an internal combustion engine’s efficiency and power output by forcing extra air into the combustion chamber. This improvement over a naturally aspirated engine’s power output is due to the fact that the compressor can force more air—and proportionately more fuel—into the combustion chamber than atmospheric pressure alone.
which parts are consist of the turbocharger?
There are three main parts of a turbocharger : Turbine,Compressor and Central Hub. The wheels of the turbine and compressor are contained in their own conical housing. The turbine side is usually made of cast iron material. The compressor side is usually made of aluminum alloys and it also consists of two parts. A turbocharger is basically a combination of a compressor and a turbine, both mounted on a common shaft. Actually, Turbocharger uses the exhaust gases of the engine itself, to rotate the turbine which in turn moves the compressor.
What is the function of a turbocharger?
In a turbocharged engine, however, the air is compressed so that more oxygen will fit in the combustion chamber, dramatically increasing the burning power of the engine. The turbocharger is composed of two main parts: the compressor, which compresses the air in the intake; and the turbine, which draws the exhaust gases and uses them to power the compressor. in other words, the more compressed the air is, the higher the boost.
A turbocharger has its drawbacks. First and foremost, a turbocharged engine must have a lower compression ratio than a normally aspirated engine. For this reason, one cannot simply put a turbocharger on an engine that was intended for normal aspiration without seriously undermining the life and performance of the engine. Also, a lower compression ratio means the engine will run less efficiently at low power.
Another major drawback of a turbocharger is the phenomenon known as turbo lag. Because the turbocharger runs on exhaust gases, the turbine requires a build-up of exhaust before it can power the compressor, Additionally, the inlet air grows hotter as it is compressed, reducing its density, and thereby its efficiency in the combustion chamber, a radiator-like device called an intercooler is often used to counter this effect in turbocharged engines.
