2. WHAT IS SUPERCHARGER?
A supercharger is an air compressor used for
forced induction of an internal combustion engine.
The greater mass flow-rate provides more oxygen
to support combustion than would be available in a
naturally aspirated engine, which allows more fuel
to be burned and more work to be done per cycle,
increasing the power output of the engine.
8. Roots Type
The Roots type
supercharger or
Roots blower is a
positive displacement
lobe pump which
operates by pumping
fluids with a pair of
meshing lobes not
unlike a set of
stretched gears. Fluid
is trapped in pockets
surrounding the lobes
and carried from the
intake side to the
exhaust
9.
Centrifugal Type
The centrifugal-type
supercharger is an enginedriven compressor used to
increase the power output of an
internal-combustion engine by
increasing the amount of
available oxygen by
compressing air that is entering
the engine. This type of
supercharger is practically
identical in operation to a
turbocharger, with the
exception that instead of
exhaust gases driving the
compressor via a turbine, the
compressor is driven from the
crankshaft by a belt, gear or
chain drive.
10.
Screw Type
Lysholm is also called screw
type supercharger.
The supercharger consists
of 2 screws, one with male
threads and another with
female threads. They closely
mesh together. When they
rotate, air is captured
between the screws and the
housing while being pushed
from the inlet towards the
outlet. Moreover, the space
gets smaller and smaller as
it moves forward, so
Lysholm performs internal
compression and enables
higher boost pressure than
Roots type supercharger.
19. ADVANTAGES OF SUPERCHARGER
Advantages of a Supercharger
1). Increased power
2). No lag – Consistent power delivery
3).Generally better throttle response
4). No Special Procedures or extra maintenance
5). Centrifugal Superchargers are more efficient at
higher RPM
6). Roots & Twin Screw Superchargers are efficient
at low RPM
7). Easier to tune
8). Easier to install than turbochargers
20. DISADVANTAGES OF SUPERCHARGER
1). Consumes a lot of power from the engine
(therefore not very efficient)
2). Increases the strain on the engine
3). Increases the strain on the running gear
4). Expensive
5).Noise
