With the vast variety of automotive applications, the ignition system has a vital role as it generates a spark. It heats an electrode to a high temperature so that the fuel-air mixture can be ignited in all spark-ignition internal combustion engines. other automobiles including stationary and movable applications are also designed with the system, which may include gas-fired and oil-fired boilers, rocket engines, etc. This is the reason why various types of ignition systems have been in existence.

However, spark-ignition petrol (gasoline) internal combustion engine is the most dependent on the system of both car and motor motorcycles. Today we’ll be looking at the definition, function, applications, components, diagram, types, and working of the ignition system in internal combustion engines. We’ll also be looking at the advantages and disadvantages of the ignition systems in their various types.

Ignition system definition

An ignition system is a system used in some types of an internal combustion engine, often a petrol engine to ignite the fuel-air mixture. This ignition is purposely performed so that the explosion in the combustion chamber can be accomplished. This is to say, the spark that occurs in the ignition system (spark plug) causes the fuel-air mixture to burn.

Just as earlier mentioned, the ignition system is featured in spark-ignition internal combustion engines, although it’s also employed in some other mechanical applications. But it’s quite popular on the gasoline engine. well, the process is different in compression ignition diesel engines as the fuel-air mixture is ignited by the compression heat which causes the elimination of the spark plug. This is another topic of discussion you can check out below.

Induction coil systems

Magneto systems were superseded by systems utilizing an induction coil as batteries started to appear more frequently in automobiles (as a result of the greater use of electric starter motors). The 1908 Ford Model T and the 1886 Benz Patent-Motorwagen both featured a tremble coil ignition system, in which the tremble disrupted the current through the coil and generated a flurry of sparks during each firing. At the proper time during the engine cycle, the tremble coil would turn on. The four-cylinder engine of the Model T has a tremble coil for each cylinder.

Distributor-based systems

Charles Kettering created a better ignition system at Delco in the United States, and it was first used in Cadillac’s 1912 vehicles.A single ignition coil, breaker points, a capacitor (to stop the points from pulling at break), and a distributor (to send the right amount of current from the ignition coil to the right cylinder) made up the Kettering ignition system. Due to its reduced price and relative simplicity, the Kettering system became the standard ignition system in the car industry for many years.

Types of ignition system

Below are the three basic types of ignition systems used in spark-ignition internal combustion engines:

Magneto ignition system:

In the magneto types of the ignition system. magneto serves as the major component used for creating the energy of high voltage. This high voltage is then used for the generation of electricity which is further used to run vehicles. The system is a combination of a distributor and a generator built as one unit. This makes it different from the conventional distributor that creates spark energy without external voltage.

Electronic ignition system:

The electronic types of ignition system are fully controlled electronically and are powered by a battery, unlike the previous one that uses magneto. It has negative and positive terminals; the negative terminal is grounded while the positive is connected to the ignition switch. So, when the switch is on, power is supplied to the electronic ignition module through the wires. The power is then sent to the ignition coil that has two winding; primary winding and secondary winding. These windings are insulated and the primary is thicker than the secondary winding. There is a rod between the windings that generate a magnetic field. Finally,

Battery ignition system:

The battery types of an ignition system are widely used in automobiles to produce sparks using spark plugs with the aid of a battery. It’s often found in 4-wheeler vehicles but is now used in two-wheeler vehicles that obtain current from a 6-volt or 12-volt battery in the ignition coil. Read the full article below!

Components of the ignition system

Below are the components of the different types of the ignition system and their functions:

Magneto ignition system

The components of the magneto ignition system include a magneto, distributor, capacitor, cam, contact breaker, and ignition switch. Their function has been explained in the full article.

Battery ignition system

The components of the battery ignition system battery, are the ignition switch, the ignition coil, and the ballast resistor. Its components also contain a contact breaker, distributor, capacitor, and spark plug. Check the full article to see their function. Finally,

Electronic ignition system

Components of the electronic ignition system also include a battery, distributor, capacitor, ignition control module, armature, ignition coil, and spark plug.

Working principle

The working of an ignition system is less complex and can be easily understood. It is obvious with the above explanation of the above sections you are now familiar with the functional parts and the operation of the system. Most of the types of ignition systems work with batteries but few are able to generate power themselves. However, with the video below you will learn the working of the various types of ignition systems.
