Turbocharger and supercharger boosted power by reusing exhaust air to get power. It mainly discuss about turbocharger working and supercharger working. In this presentation includes turbocharger diagram and supercharger diagram for more understanding. Turbocharger moto is to deliver high torque from used gases.Turbocharger and supercharger really biggest revolution in automobile industry.Turbocharger and supercharger on same engine can enhance power but it may increases weight and tension on engine and gear.it may disturbs gear cycle in engine.

AND
SUPERCHARGER

2. INTRODUCTION
 HISTORY
 BASIC PRINCIPLES
 APPLICATION

3. Three possible methods utilized to increase the air consumption
of an engine are as follows:
Increasing the piston displacement: This increases the size and weight of
the engine, and introduces additional cooling problems.
Running the engine at higher speeds: This results in increased
mechanical friction losses and imposes greater inertia stresses on engine
parts.
Increasing the density of the charge: This allows a greater mass of the
charge to be inducted into the same volume.

4. Definition
The most efficient method of increasing the power
of an engine is by supercharging, i.e. increasing
the flow of air into the engine to enable more
fuel to be burnt.
• A Supercharger is run by the mechanical drive,
powered by engine power .
• A turbocharger uses the otherwise unused
energy in the exhaust gases to drive a turbine
directly connected by a co-axial shaft to a rotary
compressor in the air intake system.

6. Need of turbocharger and super charger
• For ground installations, it is used to produce
a gain in the power out put of the engine.
• For aircraft installations, in addition to
produce a gain in the power out put at sea-
level, it also enables the engine to maintain a
higher power out put as altitude is increased.

7. Working principle of a turbocharger

8. • A turbocharger is a small radial fan pump driven by the
energy of the exhaust gases of an engine.
• A turbocharger consists of a turbine and a compressor on
a shared shaft.
• The turbine converts exhaust to rotational force, which is in
turn used to drive the compressor.
• The compressor draws in ambient air and pumps it in to
the intake manifold at increased pressure, resulting in a
greater mass of air entering the cylinders on each intake
stroke.

9. Based on the use of compressor
• Centrifugal type
• Roots type
• Vane type
Types of super charger:
Components of turbocharger
•Air compressor
•Turbine
•Intercooler

car

11. Advantages of turbocharger
• Increase in horse power
• Better fuel economy
• Smaller engine more power
• Efficiency

12. Disadvantages of turbocharger
•Turbo lag
