A turbocharger is a device designed to increase the efficiency and power output of an internal combustion engine by forcing extra air into the combustion chamber. This results in better fuel combustion and increased engine performance without the need for added displacement.

By utilizing exhaust gases to drive a turbine, a turbocharger compresses the intake air before it enters the engine, leading to more power generation. This technology is commonly used in automobiles, trucks, and other vehicles to improve fuel efficiency and overall performance.
