Air compressor or blower used in piston-type
With the additional air, more fuel is burned, and the engine's power is increased. In aircraft engines, supercharging compensates for the reduced atmospheric pressure at high altitudes. Development of the gas {{link=turbine">turbine , which requires a constant flow of air and fuel, led to the turbosupercharger, a centrifugal blower driven by a small gas turbine powered by the exhaust gases from the engine cylinders.
