Turbocharger: Description and Operation

PURPOSE
A turbocharger is used to force more air into the engine cylinders. Exhaust gas energy is used to turn the turbine wheel and shaft. At the other end of the shaft is the compressor wheel. The compressor wheel draws air in and forces it into the engine cylinders through the intake manifold.

Supplying increased air flow to the engine provides:

- Improved engine performance
- Lower exhaust smoke density
- Improved operating economy
- Altitude compensation
- Noise reduction.
