/sooh"peuhr chahr'jeuhr/, n.a mechanism for forcing air into an internal-combustion engine in order to increase engine power.[1920-25; SUPERCHARGE + -ER1]
* * *
Air compressor or blower used in piston-type internal-combustion engines to increase the amount of air drawn into the cylinders by the movement of the pistons during each intake stroke.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 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.* * *
in piston-type internal-combustion engines, air compressor or blower used to increase the intake manifold pressure of the engine. Higher pressure increases the mass of air drawn into the cylinders by the pumping action of the pistons during each intake stroke. With the additional air, it is possible to burn more fuel per cycle, and the power of the engine is thus increased.In aircraft piston engines, supercharging compensates for the reduced atmospheric pressure at high altitudes. Development of the gas turbine, which requires constant flow of air and fuel, brought the introduction of the turbosupercharger, or simply turbocharger, a centrifugal blower driven by a small gas turbine powered by the exhaust gases from the engine cylinders.* * *
