A turbocharger is a shortened name for the technical and original name of super-turbocharger. It is also same as a supercharger and is used for the same task but the difference arises in their attachment, efficiency.
A turbocharger unlike supercharger is linked with exhaust gases and gets it power from them which does not affect efficiency as is affected by a supercharger. The supercharger is connected to crankshafts using a specific belt which reduces the efficiency of a car. A turbocharger is also used to increase the power and torque of a car and all that work is also done by turbocharger which a supercharger does. Working of a supercharger and it’s used has been explained in the previous post.
