THE FUNCTION OF TURBOCHARGER Turbos are, at times, fitted after market by car tuners and enthusiasts, although most cars and  trucks come with them installed from the manufacturer. Though particular reasons may differ, all  turbos boost power output from an engine that would otherwise be limited to less engine power. The main function of a turbocharger is to enhance the power output of an engine without making  modification   in   the   engine   itself.   Generally,   an   engine   would  have   to  be  designed   larger  and  accordingly   heavier   to   gain   power.   In   contrast,   turbo   chargers   are   much   smaller   and   lighter.  Moreover, a turbo is powered by the exhaust gases of the engine, which would normally leave the  vehicle unused.  The   purpose   of   a   turbo   can   be   considered   of   as   starting   at   the   exhaust   opening.   Exhaust  emissions from the engine go through the turbo before leaving through the exhaust system of the   vehicle. The flow of these gaseous emissions prompts a turbine wheel inside the turbo to spin.  On the other side of this turbine, along the same axis, there is a different wheel at the intake  opening   of   the   turbo.   At   the   intake   opening   of   the   turbo,   here   is   a   second   wheel   that   spins  everytime the exhaust­side turbine wheel spins because they are linked by the same shaft. This   second wheel is called the impeller wheel because it’s revolving constricts the air coming into the  turbocharger  on   the   intake   opening.   This  compressed   air   is   then   transported   into   the   engine  intake and because of the higher density of oxygen molecules, the engine supplies more fuel for   each piston stroke ensuing in amplifying power. Inside the engine, the compressed air is used up  and the remnants become exhaust emissions. This exhaust gas has more energy because it had   been compressed and burnt with more fuel. This will result in the exhaust end turbine of the turbo  to spin faster than earlier. The cycle will continue again and due to this, the turbo will continue to  increase the compression of the intake air. However, too much power can damage the engine. To   control   the   amount   of   air   pressure   a   turbo   produces,   a   control   system   must   be   used.  Restricting the speed of the turbine wheel limits the speed of the intake opening compressor  wheel, which will limit the quantity of air compression.
