Turbocharging System: Operation: Notes

Air is drawn in through air cleaner and carburetor assembly. Carburetor mixes a metered amount of fuel with incoming air and passes it into compressor assembly. As engine load increases and throttle is opened, more air/fuel mixture flows into combustion chambers. As this mixture is burned, a greater volume of exhaust gas enters exhaust system. This gas is directed into turbocharger turbine housing.

Some energy contained in exhaust gas is used to increase speed of turbine wheel. The turbine wheel is connected by a shaft to a compressor wheel. As the compressor wheel spins faster, it compresses incoming carburetor air/fuel mixture and forces a denser charge into combustion chambers producing a higher power output.
