Volvo's new engine: Turbocharger? Supercharger? What is this thing?
Valeo calls its device, left, an electric supercharger. It uses an electric motor -- not exhaust gasses -- to spin the impeller. A traditional supercharger looks like the one from Eaton, middle. It is driven by a fan belt connected to the front of the engine. Turbocharges like the one made by Honeywell, right, have an exhaust gas driven turbine on one side and an impeller on the other.
