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.

CONSTRUCTION OF SUPERCHARGER
OPERATION OF SUPERCHARGER
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

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.

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.

ADVANTAGES AND DISADVANTAGES OF
SUPERCHARGED
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

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
