So If you find this articles helpful, please let us know in the comment box, either if any correction required too, also let us know in the comment box.

Magneto Ignition System Definition:

The magneto ignition system is an ignition system in which we use magneto for the generation of electricity and further that electricity is used in several things like 

To run the vehicles.

This is basically used in two-wheeler vehicles (SI Engine) nowadays.

Rotating magnet produces high voltage.

  • And also This is used in various places like:
    • Tractors, Outboard Motors
    • Washing Machines
    • Buses
    • Power Units, Marine Engines, and Natural Gas Engines.

Magneto Ignition System Main Parts / Construction:

The main parts are:

  1. Transformer core
  2. Contact Breaker
  3. Cam
  4. Capacitor
  5. Ignition Switch
  6. Distributor
  7. Spark Plug

Transformer core:

  • Primary Winding:
  • Secondary Winding:
    • This winding has more turns of wire ( 1000 of turns f wire ) as compared to the primary winding.
    • This is connected to the Distributor (Which is having rotor )

Contact Breaker:

  • The contact breaker is regulated by the cam and when the breaker is open, current flows through the condenser and charges it.

Cam:

  • Cam is connected to North and south magnet.

Capacitor:

  • The main work of the capacitor is to Store the charger.

Ignition switch:

  • Works for of and on the vehicles and this is set to the parallel of the capacitor because it helps to avoid the damage of excessive air.

Distributor:

  • This is connected to the spark plug and Distributor having the rotor.

Spark Plug:

  • The main work of the spark plug is firing the explosive mixture in the IC engine.

Magneto Ignition System Working Diagram:

As we studied the battery ignition system, The working principle of the magneto ignition system is similar, but in a magneto system,

It’s used to produce energy but in the battery case, it wasn’t.

The Following procedure how it works:

When the engine of the system starts, it helps magneto to rotate and thus it’s producing the energy in the form of high voltage then,

One end of the magneto is grounded through contact breaker, and ignition capacitor is connected to its parallel.

The contact breaker is regulated by the cam and when the breaker is open, current flows through the condenser and charges it.

Magneto Ignition System

now the condenser is acting as a charger now, the primary current flow is reduced, thus reducing the overall magnetic field, generated in the system.

This increases the voltage in the condenser.

This increased high voltage in the condenser will act as an  EMF thus producing the spark, at the right spark plug through the distributor. and

At the starting stage, the speed of the engine is low and hence the voltage generated by the magneto is low.

But as the rotating speed of the engine increases, it also increases the voltage generated by the magneto.

And the flow of the current is also increased.

Preparing for Competitive Exam? If Yes, then must go for this book:

The most valuable and trusted Mechanical Objective book by R S Khurmi 5000+ Objective.

Magneto Ignition System Advantages, Disadvantages, and Application:

Advantages:

  1. This  requires less maintenance as compared to the Battery ignition system and also
  2. This is more useful because no battery is used.
  3. Occupies less space.
  4. An electric circuit is generated by the magneto
  5. No battery is needed, so no problem of battery discharge
  6. Efficiency improves due to high-intensity spark.

Disadvantages:

  1. During starting, quality of spark is poor due to low speed
  2. This is a little expensive as compared to another ignition system.

Application:

  1. This system is used for the generation of electricity (In case of Battery system their Battery is used)  and to run the vehicles.
  2. This is basically used in two-wheeler vehicles (SI Engine) nowadays.
  3. Rotating magnet produces high voltage.
  • And also This is used in various places like:
    • Tractors, Outboard Motors
    • Washing Machines
    • Buses
    • Power Units, Marine Engines, and Natural Gas Engines.
