1 5.6.1 Uses of Supercharged Engines
Supercharged engines are widely used at high altitudes. At a higher altitude the suction pressure of the charge in the cylinder reduces, which in turn reduces the power output. To overcome this reduction in power, the engines are generally supercharged. In the case of a motor vehicle engine climbing a hill, the power output reduces gradually. Therefore, with increasing height the degree of supercharged should be increased. Supercharging is necessary in the case of racing-car engines and aircraft engines where the specific output is of prime importance. Supercharging also reduces the bulk of the engine, so it is used where a limited space is only available for the engine.
