TURBOCHARGED VSSUPERCHARGED

Keeping the air that enters the engine cool is an important part of the design of both superchargers and turbochargers. Compress-ing air increases its temperature, so it is common to use a small radiator called an intercooler between the pump and the engine to reduce the temperature of the air.

There are three main categories of superchargers for automotive use:

 

1) Centrifugal turbochargers – driven from exhaust gases.

  • 2) Centrifugal superchargers – driven directly by the engine via a belt-drive.
  • 3) Positive displacement pumps – such as the Roots, Twin Screw (Lysholm), and TVS (Eaton) blowers.
