ABSTRACT
Supercharging uses a mechanically driven “air pump” to artificially supply the engine cylinders with a greater amount of air/fuel mixture than would be taken in under normal atmospheric conditions. The basic concept in most supercharging devices is to increase the outlet pressure over the inlet pressure and therefore the density of the air delivered to an engine above ambient atmospheric conditions. This in turn increases the mass of air drawn into the cylinders during each intake stroke. Then, if the optimum air-to-fuel ratio is still maintained, more fuel can be combusted to produce more power output.
