21. EGR
It is a Nitrogen oxide emission reduction technique .
It recirculates a part of exhaust gas to the intake manifold.

22. Location of EGR
EGR valve
 It is located between inlet and exhaust manifold.
 It provides passage for exhaust gases from exhaust to inlet manifold
Cylinder head
Intake manifold

23. Components of EGR

24. EGR in 651 engine
EGR valve
EGR cooler
Intake manifold
Turbocharger
Exhaust manifold
Per-cooler

25. Automatic Transmission
• It is a medium which Transmits the Engine Power to the Wheels
 Thetransmission is located between engineand propeller shaft

26. Automatic Manual
Comparison between Automatic & Manual Transmission
 Gears shifts Automatically  Gears are shifted Manually
 Torque converter is
present
 Clutch is present
 Uninterrupted power
flow
 Interrupted power flow

27.  A turbocharger is an
exhaust driven turbine.
 It compresses the air
and sent it to engine.
 Which boost the
engine’s power.

28.  The technique of sending forced air into
combustion chamber in an I.C engine was
invented by Gottlieb Daimler in 1885.
 The turbocharger was invented in
1905 by Swiss engineer “Alfred
Buchi”.

29.  The world's first diesel automobile with
turbocharger was Mercedes 300SD introduced in
1978.

30.  Uses waste energy of
exhaust gases for driving
the turbine.
 Produces more power
with same engine
capacity.
 Reduces fuel consumption
as more amount of air is
forced in.

31.  It is the ratio of volume of air intake to total
cylinder volume.
Volumetric efficiency =__________________Volume of air intake
Total cylinder volume
x 100%
Volume of air intake=300 cc
Total volume of cylinder=400 cc
Volumetric efficiency= _____
= 75%

33. INTRODUCTION TO STEERING SYSTEM
 The steering system is the
collection of component and
linkages.
 It allows a vehicle to follow
certain path desired by the
driver through the steering
wheel.

34. COMPONENTS OF STEERING SYSTEM
 Steering wheel
 Steering shaft
 Steering gear box
 Tie rod
 Tie rod ends

35. ELECTRICAL POWER STEERING SYSTEM
 It is electrically operated.
Electric motor is used for
the steering assistance.
 Control Unit takes the
several values i.e. vehicle
speed and command the motor
to switched on.
 For motor, Current is drawn
from the charging system.
