How does a turbocharger work ?
A turbocharger is an exhaust-driven turbine which drives a centrifugal compressor wheel. The compressor is usually between the air filters and the engine intake manifold, while the turbine is bolted to the exhaust manifold.
The exhaust gases from the cylinders passes through the turbine blades, causing the turbine wheel to spin, thereby driving compressor wheel . The compressor is directly connected to the turbine by a shaft.
Air density is increased by means of a rapidly rotating compressor wheel. So it allow compressor suck in air through the air filters and passes this into the engine.
This allows the engine to efficiently burn fuel, and so producing more horsepower.
