Theres 3 major parts to a turbo.
1. Compresser housing.
2. Turbine housing.
3. CHRA (center housing rotating assembly).
CHRA contains the bearings, seals, shaft, etc.... The tubine and compressor wheels are mounted to the CHRA.
Air gets sucked in through the compressor housing (inlet). Its then compressed and blown out the compressor outlet, which is also part of the compresser housing.
Exhaust enters through the turbine housing (inlet) and also leaves through the same housing (outlet).
Since the compressor and turbine wheels are connected together with a shaft, when one spins the other also spins. Turbos are driven by exhaust.
Air enters turbo ---> air is compressed and blown out of the turbo ----> enters engine ---> combustion ---> enters turbo (turbine inlet) ---> leaves turbo (turbine outlet) ---> exhaust.
