Turbocharger

Practically, turbocharger is connected to your vehicle’s exhaust line. It is a centrifugal air pump, and the exhaust gas of your engine drives this pump. You can ask why it is designed to run by exhaust gas. Yes, it is a good question. Now, be clever to think about its operation and power source. 

If automakers use engine generated power to run this device, it will require an extra energy and fuel to operate. It will add extra money to your annual operating cost. Otherwise, exhaust gases escape at high velocity and temperature. If we can utilize this energy, it will be a great saving. So, automakers have designed it to run by the energy of exhaust gases.
