The turbo air intake in a turbocharged engine works similarly to a jet engine. Turbocharged engines use the exhaust gas to drive a turbine in the engine. The air compressor pushes air into the cylinders, providing them with the power to burn more fuel each second.
A turbocharged engine uses both cool air and the vehicle's exhaust to create more power. Cool air enters the intake and travels toward the compressor, where the fan helps draw air in. As the air enters, the compressor heats and compresses the air and then blows it back out. Once the hot air leaves the compressor, it enters the heat exchanger, which cools it down. The cooled air goes to the cylinder's air intake valve, where it is forced into the cylinder.
This process burns more fuel, giving the engine more energy. After using the energy, the exhaust gas exits the engine through the exhaust outlet and blows past the turbine fan, making it spin. The turbine then sends the exhaust gas out of the vehicle.
Turbochargers are simple, inexpensive ways to give an engine more power. Many newer model cars come with turbocharged engines, but those that don't may have an aftermarket kit installed. Turbochargers are most effective on cars with four or six cylinders, although they work on larger engines as well.
