What is a turbocharger?

A turbocharger is an air pump. It supplies air for the engine combustion process at higher pressure and density than ambient air. This higher concentration of oxygen provides a greatly improved combustion process, offering more power, cleaner emissions and improved engine torque output, while reducing the pumping losses. This means better all-round engine performance.

A turbo comprises a turbine stage and a compressor stage.

The turbine is driven by waste exhaust gas from the engine which, in turn, drives the compressor, which draws in ambient air and compresses it. This process results in a much more efficient combustion process.
