This document provides an overview of the Auto Spandan - 2015 event organized by Mr. Shobhit Sharma, Mr. Susheel Kumar, and Mr. Ajay Kumar. It then summarizes the key specifications of a Maruti 800cc engine, including its type, displacement, configuration, power and torque outputs, and mileage. Finally, it lists and provides brief descriptions of 20 main parts of the engine, including the cylinder head, block, cam shaft, crank shaft, pistons, intake/exhaust manifolds, valves, distributor, flywheel, and alternator.

1. WELCOME TO ALL PARTICIPANT IN
AUTO SPANDAN – 2015
Organized by:-
Mr. Shobhit Sharma(Dean Academics)

4. There are various parts of engine.
1. Cylinder head with cam shaft & rocker arm
assembly
2. Cylinder block.
3. Oil pan.
4. Crank shaft.
5. Piston, piston ring and connecting rod.
6. Timing set( timing belt , crank gear pulley,
cam gear pulley and adjusting bearing).
7. Flywheel.
8. Alternator.
9. Carburettor.

5. 10. Intake manifold.
11. Exhaust manifold.
12. Inlet & outlet valves.
13. Distributor case & distributor assembly.
14. Spark plugs.
15. Different types of gasket.
16. Ignition coil.
17. Bearing caps.
18.Oil seal housing.
19. Oil strainer.
20. Fuel filter.

6. CARBURETTOR
Carburettor is used
in only S.I.
engines(i.e. petrol
engine).It mixes the
air-fuel ratio in
desired amount and
transfer to the inlet
manifold.

7. INTAKE
MANIFOLD
Intake manifold is
very important part
through which air-
fuel mixture enter
to the combustion
chamber.

8. EXHAUST
MANIFOLD
It is an also
important part
that passes burnt
gasses through out
from the cylinder.

9. OIL SEAL
HOUSING
Oil seal housing
is used to make a
leakage proof for
lubricating oil . It
is connected to
the flywheel side.

10. INLET &
OUTLET
VALVES
In three cylinder
engine 3- inlet
valves and 3-
outlet valves are
used.

11. CYLENDER
HEAD
Cylinder head
is shown in fig.
The cylinder
head consists of
camshaft ,
valve and
rocker arm
assembly.

12. CYLINDER
BLOCK
Cylinder block as
shown in fig. In
cylinder block
piston moves
upward(T.D.C.)
and
downward(B.D.
C.) .

13. OIL PAN
Oil Pan in shown
in fig. In which
lubricating oil
can be collect by
the help of oil
strainer.

14. CRANK
SHAFT
Crank shaft is
shown in fig. .
Which rotates
with the help of
fly wheel and
connecting rod
is mounted on
the crank shaft.

15. PISTON
Piston is shown in
fig. For each
cylinder , separate
piston are used .In
the piston 3 types of
rings are used.
1. Compression ring.
2. Expander ring.
3. Oil ring.

16. TIMING SET
Timing set consist of
timing belt
,adjusting bearing
,crank gear pulley
,cam gear pulley etc.
It sets spark timing
in cylinder block.

17. DISTRIBUTOR
Distributor as
shown in fig.
which is used to
ignite the air-fuel
ratio in the
cylinder. In this 3-
cylinder engine
the fire ratio is 1-
3-2.

18. FLYWHEEL
Flywheel is used to
absorb the energy
and transmits this
energy to the
transmission box. It
rotates through the
starter motor.

19. ALTERNATOR
Basically alternator is
used to generate the
electric power and
behind the alternator
through the wire.It is
connected to the
battery. Alternator is
used to charge
battery also.

20. CAM SHAFT
It operates the valve
mechanisms
upward and
downward through
the rocker arm
assembly.This cam
is known tangent
cam.

21. STARTER
MOTOR
It is used to
produce the
power in flywheel
and to start the
engine. It is also
known as self.
