TurboCharger - Animation

I believe there are still many people who don't really know how turbocharger functions.
This video shows a short animation of how air flows through turbocharger.
Its function is to increase air flow into the engine relying on exhaust gas flow. It also increases air pressure into the combustion chamber. That's why we sometimes hear the word "boost" when talking about turbocharge system.
Hope this video helps to understand turbocharger better.
