The term 'supercharged engine, for short' can be abbreviated to 'turbo' (5 letters). A turbocharged engine is an internal combustion engine that has been modified to increase its power output by using a turbine to compress air and force it into the combustion chamber. This process increases the amount of oxygen available for combustion, allowing the engine to produce more power than a naturally aspirated engine. The increased power output of a turbocharged engine makes it ideal for high-performance applications such as racing cars and aircraft.
