What are the three main parts of a typical turbosupercharger?

• A. Throttle body, intake manifold, exhaust pipe.
• B. Compressor assembly, turbine wheel assembly, and full floating shaft bearing assembly.
• C. Telemetry module, turbine housing, sensor.
• D. Compressor, fuel pump, oil cooler.

Answer: (B)

The main idea is that a turbosupercharger is built from two rotating machines that share a common shaft, with a bearing system that keeps them aligned and spinning together. The three main parts are the compressor assembly, which draws in and compresses air for boost; the turbine wheel assembly, which is driven by exhaust gases to power the shaft; and the full floating shaft bearing assembly, which supports the shaft and allows the turbine and compressor to rotate together with proper lubrication and seals. The compressor side provides the increased air density, the turbine side harvests energy from exhaust, and the bearing assembly ties everything together and keeps it smooth. Other options mix in engine components like fuel pumps or sensors or refer to individual pieces that aren’t the three defining assemblies of a turbosupercharger.
