SUPERCHARGERS AND TURBOCHARGERS

LEARNING OBJECTIVE: Describe the operation of and the differences between superchargers and turbochargers.

Supercharging and turbocharging is a method of increasing engine volumetric efficiency by forcing the air into the combustion chamber, rather than merely allowing the pistons to draw it naturally. Supercharging and turbocharging, in some cases, will push volumetric efficiencies over 100 percent.
