What is the working principle of turbocharger?

A turbocharger is a device used to increase the efficiency and power output of an internal combustion engine by forcing more air (and consequently more fuel) into the combustion chamber. The working principle of a turbocharger involves several key components and steps:

  1. Using Exhaust Gas: When an engine runs, it produces exhaust gases as a byproduct. A turbocharger is connected to the engine's exhaust system and uses these gases to work.
  2. Spinning a Turbine: The exhaust gases enter the turbocharger and make a part called a turbine spin. This turbine is connected to a shaft that also drives another part called a compressor.
  3. Compressing Air: The compressor pulls in outside air and squashes it down, making it denser. This means there’s more air packed into the same space.
  4. Feeding More Air to the Engine: This denser, compressed air is then pushed into the engine. With more air coming in, the engine can burn more fuel at the same time.
  5. More Power: By using this extra air, the engine can produce more power, which means better performance without making the engine larger.
  6. Cooling the Air: Sometimes, the compressed air is cooled before it goes into the engine. Cooler air is denser, which helps the engine make even more power.
  7. Controlling Boost: To make sure the turbocharger doesn’t create too much pressure (which could harm the engine), a part called a wastegate controls how much exhaust gas goes into the turbocharger.

In short, a turbocharger is a clever device that uses the engine's waste gases to shove more air (and fuel) into the engine, making it run stronger and more efficiently!
