1. VIDEO OF IGNITION SYSTEM

3. It is the electrical system in an
engine that causes the fuel to burn
so that the engine begins working.

4. It is the electrical system in an
engine that causes the fuel to burn
so that the engine begins working.
It is a
device that
is used to
start a car’s
engine.

5. What is the purpose of
Ignition System?

6.  To ignite the compressed air fuel mixture in
the engine combustion chamber.
 It delivers an electrical spark that jump a gap
of combustion chamber ends of the spark
plugs to start combustion.
a chemical reaction that occurs when oxygen combines with other
substances to produce heat.

7. Components in
Ignition System

8. Battery

9. Battery-Battery- A battery is a
source of electric power
consisting of one or more
electrochemical cells with
external connections for
powering electrical devices
such as flashlights, mobiles
phones, and electric cars.

10. Battery

11. Ignition Switch

12. Ignition Switch
- It connects the ignition coil to the
battery when the ignition is on.

13. Ignition Switch
- It connects the ignition coil to the
battery when the ignition is on.
-When the ignition key is turned to
start, the starting motor cranks the
engine for starting.

14. Ignition Switch
- It connects the ignition coil to the
battery when the ignition is on.
-When the ignition key is turned to
start, the starting motor cranks the
engine for starting.

15. Ignition Switch
- It connects the ignition coil to the
battery when the ignition is on.
-When the ignition key is turned to
start, the starting motor cranks the
engine for starting.

16. Ignition Coil

17. Ignition Coil
- It is the step-up transformer that
raises the battery voltage to a high
voltage that may reach 25, 000
volts.

18. Ignition Coil
- It is the step-up transformer that
raises the battery voltage to a high
voltage that may reach 25, 000
volts.

19. Ignition Distributor

20. Ignition Distributor
- It does two jobs:

21. Ignition Distributor
- It does two jobs:
1. It has a set of contact
points or breaker points
that work as a fast-acting
switch

22. Ignition Distributor
- It does two jobs:
1. It has a set of contact
points or breaker points
that work as a fast-acting
switch
2. It distributes the
high-voltage surges to the
spark plug in the correct
firing order.

23. Ignition Distributor
- It does two jobs:
1. It has a set of contact
points or breaker points
that work as a fast-acting
switch
2. It distributes the
high-voltage surges to the
spark plug in the correct
firing order.

24. Ignition Distributor
- It does two jobs:

25. Secondary (Wiring) Ignition Cables

26. Secondary (Wiring) Ignition Cables
- It includes the coil wire and the
spark plug wires.

27. Spark Plugs

28. Spark Plugs
- It has two solid-metal conductors
called electrodes positioned to form
a gap.

29. Spark Plugs
- It has two solid-metal conductors
called electrodes positioned to form
a gap.

30. Spark Plugs
- It has two solid-metal conductors
called electrodes positioned to form
a gap.

31. Purpose of Primary
and Secondary
Circuit

32. Primary Circuit
 It carries low voltage.

33. Primary Circuit
 It carries low voltage.
 It operates only on battery current and is
controlled by the breaker points and the
ignition switch.

34. Secondary Circuit
