  • Function: Spark plugs are activate components that generate sparks to ignite the fuel-air mixture in the engine cylinders.

  • Location: Installed in the cylinder head, each spark plug is connected to the ignition’s system.

2. Ignition’s coil

  • Function: The ignition’s coil transforms low-voltage electricity from the battery into high-voltage electrical pulses, providing the necessary spark for combustion.

  • Location: Typically located near the machine, the ignition’s coil is connected to the distributor or directly to the spark plugs.

3. Distributor

  • Function: In traditional ignition systems, the distributor distributes high-voltage current from the ignition’s coil to each spark plug in the correct firing order.

  • Location: Found near the machine, the distributor has a rotor that directs the current to individual spark plug wires.

4. Ignition switch

  • Function: The ignition switch is a key-operated electrical switch that controls power distribution to various vehicle systems, including the ignition’s system.

  • Location: Usually located on the steering column, dashboard, or console, the ignition switch enables or disables the electrical system.

  5. Combustion and Machine Start:

    • The ignited fuel-air mixture creates controlled explosions in the cylinders, driving the pistons and starting the machine.

2. Role of each component in starting the machine

  • Ignition Switch:

    • Enables or disables the flow of electrical power to the ignition’s system.

    • Initiates the process by turning to the “ON” position.

  • Ignition‘s Coil:

    • Converts low-voltage power from the battery into high-voltage pulses.

    • Provides the spark necessary for combustion.

  • Distributor (in traditional systems):

    • Distributes high-voltage current from the ignition’s coil to each spark plug in the correct firing order.

    • Ensures precise timing of ignition’s events.
