A turbocharger uses the heat energy from exhaust gases to power a turbine, which spins an air compressor to force more air into the engine. It allows an engine to produce more power without increasing engine size. A turbocharger has a turbine section, compressor section, shaft connecting the turbine and compressor, and bearing housing. It works by partially exhaust gases powering the turbine, which spins the compressor to pressurize incoming air before it enters the engine, allowing for more efficient combustion. Turbochargers are used in cars, trucks, motorcycles, aircraft and marine engines to improve power density without increasing engine size.

by the unused heat
energy normally
wasted out the
exhaust.

3. • It is a turbine driven compressor.
• It uses the waste energy from exhaust gas to increase the
charge mass of air and power of the engine.

7. BASIC INFORMATION ABOUT EMD TURBOCHARGER
• Drive–Mechanically driven (gear drive) as well as
exhaust gas driven (turbine) with an over-running
clutch
• Rated output – 6.5 kg/sec
• Pressure ratio (Compressor) – 2.8
• Charge air Temp. (after compression) 171oC
• Speed of Turbo (at rated output) – 18,950 rpm
• Lubrication – Engine lube oil and soak back system at
starting and stopping of engine.
• Compressor – Single stage, centrifugal type
• Turbine – Single stage, axial flow type

8. WHY TURBOCHARGER?
*POWER DIMINISHES WITH AN INCREASE IN
ALTITUDE.
* GAIN MORE POWER AND INCREASE ENGINE
EFFICIENCY WITHOUT ENLARGING THE
POWERPLANT.
* RECAPTURE THE HEAT ENERGY NORMALLY
WASTED OUT THE EXHAUST.

12. HOW A TURBOCHARGER WORKS
A turbocharger comprises
of a turbine and a
compressor connected by
a common shaft
supported on a bearing
system. The turbocharger
converts waste energy
into compressed air
which it pushes into the
engine. This allows the
engine to produce more
power and torque and
improves the overall
efficiency of the
combustion process.

13. SCHEMATIC DIAGRAM OF SUPERCHRGING
the combustion air is compressed by a compressor
driven directly by the engine.

14. WORKING OF EXAUST GAS TURBOCHARGING
In exhaust gas turbocharging, some of the exhaust gas energy,
which would normally be wasted, is used to drive a turbine.
the turbine is a compressor which draws in the combustion air,
compresses it, and then supplies it to the engine.

15. TURBINE SECTION IN TURBOCHARGER
the gas has passed
through the blades of
the wheel it leaves the
turbine housing via the
exhaust outlet area.

16. COMPRESSOR SECTION
The
compressor
wheel is
connected
to the
turbine by a
forged steel
shaft

17. TURBOCHARGER COMPONENTS
• The turbine housing
inlet flange acts as the
reference point for
fixing turbocharger
position
• The Turbine Wheel is
housed in the turbine
casing and is
connected to a shaft
that in turn rotates the
compressor wheel.

18. TURBOCHARGER COMPONENTS
• Compressor Cover
• Compressor Cover are
also made in cast
aluminium
• Compressor Wheel
• Compressor impellers
are produced using a
variant of the
aluminium investment
casting process.

19. BEARING HOUSING
A grey cast iron
bearing housing
provides locations
for a fully floating
bearing system for
the shaft, turbine
and compressor
which can rotate at
speeds up to
170,000 rev/min.
