Inertial supercharging effect is the result of incoming fuel/air charge developing momentum greater than intake stroke would generate alone. It is achieved by the careful design of the shape of the piston head, the valves and cam profile/valve timing which creates a vacuum that pulls more exhaust gases (and some of the intake gasses) out of the engine.
A blowoff valve is designed to release pressure in the intake system when the throttle is closed. A "recirculating" type blowoff valve releases the pressurised air back into the non-pressurized section of the intake (i.e. upstream of the turbocharger), while an "atmospheric venting" type blowoff valve dumps the air directly into the atmosphere.
An animation of the operation of a scroll-type supercharger. Air is confined between the two spirals and is compressed as it is forced towards the centre. In automotive application, the spirals would have far fewer turns. The G-Lader is a scroll-type supercharger used in various Volkswagen Passenger Cars models.
The design used a complex series of bypass valves in the induction and exhaust systems as well as an electromagnetic clutch so that, at low engine speeds, a boost was derived from the supercharger. In the middle of the rev range, a boost was derived from both systems, while at the highest revs the system disconnected the drive from the ...
A mechanically driven supercharger offers exceptional response and low-rpm performance, as it does not rely on pressurization of the exhaust manifold (assuming that it is a positive-displacement design, such as a Roots-type or twin-screw, as opposed to a centrifugal supercharger, which does not provide substantial boost in the lower rpm range), but is less efficient than a turbocharger due to ...
Distancing the supercharger from the engine via a mounting bracket greatly reduces heat transfer from the engine to the supercharger during operation. By comparison, a twin screw or roots blower which is nested in the center (valley) of the engine, will absorb heat (heat soak) during operation due to thermal transfer from the engine block and ...

The actuator consists of a linear servo actuator servomotor that controls a plunger which varies air flow through the throttle body. The position of the servomotor and hence the amount of air bypass is controlled digitally by the engine ECU. This allows the engine's idle speed to be maintained constant.
