Why turbocharger

Turbocharger is a industrial device fitted to engine, one side of turbocharger is to make an engine more powerful and to enlarge the cylinders. Another side is to add more cylinders. Both of these methods make engine less economical to run, because both use more fuel.

Another way to make an engine more powerful is to add a turbocharger to the engine. Very simply, a turbocharger is two wheels connected by a shaft. One of the wheels is a turbine, which is turned at a high speed by the heated exhaust gases coming out of the engine.

The turbine spins the second wheel, which is called a compressor. The compressor pressurizes the fresh air that is going into the cylinders, squeezing the air molecules together.

Now the engine is getting more air, so it burns its fuel better. The more air, the more combustion.
