A turbocharger (or turbo) is a device that increases an engine's power by forcing more air into the engine's cylinders. More air allows the engine to burn more fuel, producing more power without increasing the engine's size.
How it works:
Exhaust gases from the engine exhaust manifold spin a turbine wheel. The turbine is connected by a shaft to a compressor wheel.
As the turbine spins, the compressor draws in fresh air and compresses it. The compressed air is sent into the engine, allowing more fuel to be burned and generating more power.
Main parts
1. Turbine – Driven by exhaust gases.
2. Compressor – Compresses incoming air.
3. Center housing – Contains the shaft and bearings, lubricated by engine oil.
4. Wastegate – Controls boost pressure by diverting excess exhaust gases.
5. Intercooler (often used with a turbo) – Cools the compressed air to improve performance and efficiency.
