0 a device which produces more power in an engine by forcing more air into the part of it in which fuel burns --
It is frequently used as a supercharger in engines, where it is driven directly from the engine's crankshaft via a belt, chain, or gears.
Power for the supercharger can be provided mechanically by means of a belt, gear, shaft, or chain connected to the engine's crankshaft.
To achieve higher boost, the crankshaft drove a centrifugal supercharger, which also provided the scavenging needed for starting the engine from rest.
Supercharged engines make use of a sixth-generation twin vortex supercharger.
Both prototypes were research aircraft, used for testing pressurized cabins, engine superchargers, and cantilever wings.
If the engine is running under boost conditions, the pressure in the intake manifold is higher than that coming from the supercharger.
This coupled with engine oil spray out of the valve cover breathers because of the pressure of the superchargers.
A central gear tower drove the overhead camshafts, superchargers and ancillaries.
