What are the principles of Supercharging?
Virtually all modern automobiles use a four-stroke engine design (it doesn’t matter if they are gasoline or diesel powered). With this design, one stroke of the process is the air intake. Here’s how it works: When the piston moves down, it creates a vacuum so air is “sucked” into the combustion chamber. As the air is drawn into the engine, fuel is injected into the combustion chamber via the fuel injection system. Next, the intake valve closes and the piston rises up in the cylinder, compressing the air/fuel mixture. Finally, the spark plug ignites the mixture – the force of the explosion drives the piston down the cylinder, creating a reciprocating motion that is transferred to the wheels. Now, here is what happens when a supercharger is added: The rotation of the supercharger pressurizes the air going into an engine at a level that is above normal atmospheric pressure – while maintaining the chemically correct fuel-to-air ratio. How much more is called “boost” and is measures in PSA,
