How Turbo Work
A turbo is a high precision 'air pump', used to supply more air into the engine by harnessing on the usually wasted energy in the engine exhaust.
The exhaust gases (dark red arrow) drive the turbine wheel and shaft, which is coupled to the compressor wheel.When the compressor wheel rotates,fresh air (dark blue arrow) is forcedfed at high pressure into the combustion chamber (light blue arrow).
With a high concentration of oxygen per cubic volume and optimum air-fuel ration,combustion is now cleaner and more complete
