Difference Between Turbocharger and Supercharger
In this article, we will learn about the difference between turbocharger and supercharger. They both are forced induction system i.e. they compressed the air from the atmosphere and sends it to the engine cylinder. The compressed air allows a double amount of fuel to enter into the cylinder for combustion. This doubles the power of the engine. Turbocharger and supercharger perform the same operation, so most of us are unable to find a difference between them. Here in this article, I will try to clear all your doubts about turbocharger and supercharger.
