Supercharging is a method used to increase the power output of an internal combustion engine by forcing more air into the combustion chamber. This is typically achieved using a device called a supercharger, which compresses the air before it enters the engine. By providing more air, the engine can burn more fuel, resulting in greater power and efficiency. There are different types of superchargers, including roots, twin-screw, and centrifugal designs. Each type has its own advantages and is chosen based on the specific performance needs of the vehicle. Supercharging is commonly found in high-performance cars and racing vehicles to enhance speed and acceleration.
