How It
Works
Turbochargers are also known as a forced induction system. This system is known to compress the air before it gets to the intake valve on the engine. There is another system called a supercharger that uses a external compressor powered by electricity or by the engine drive belt. It is not as efficient to use superchargers because it takes energy to run the compressor, where as turbochargers are powered by exhaust fumes.
An engine goes
through 4 phases: the intake,
compression, combustion, and exhaust.
A turbocharger is set up receive the exhaust flow which spins the turbine. The turbine blades are connected to a shaft and the other side of the turbine has blades that are set up to compress air. The air from the air filter has d
direct flow to the turbo. After the air is
compressed, it is sent to the engine intake valves.
The shaft the spins between the two turbines gets to speeds up to 150,000 rpm meaning that its crucial to have very precise bearings. Regular bearings cannot handle high speeds, so most turbos use fluid bearings. Oil is a good lubricator that also cools the shaft. It also reduces the friction.
Because its mounted to the exhaust, the turbo gets hot also making the compressed air hot. There is turbo cooler for this. A turbo cooler is a radiator, but instead of water being cooled, the compressed air cooled and then sent to the engine intake.
