A turbocharger, or turbo is a turbine-driven forced induction device that increases an internal combustion engine’s efficiency and power output by forcing extra air into the combustion chamber.
This improvement over a naturally aspirated engine’s output results because the turbine can force more air, and proportionately more fuel, into the combustion chamber than atmospheric pressure alone.
Turbochargers are usually seen as power enhancements on performance cars, but today, turbochargers are becoming more regularly used to provide greater torque on small capacity engines. The advantages of using a turbo engine include improved fuel efficiency and reduced exhaust emissions.
