Being well-Considering that the ignition coil happens to be the most critical part of the ignition system, it may be of great help to be familiar with the working mechanism of the ignition coil.Whether it's a car engine or an engine for a lawn mower, the "ignition coil" is undoubtedly the most important part of it.This part of the ignition system generates a lot of power, which is necessary for the ignition of the ignition plug.But how does the ignition coil generate such a huge amount of power?You need to do it well to understand thisFamiliar with its working mechanism.In an internal combustion engine, "Ignition" refers to the process in which a spark generated by a spark plug triggers an explosion and ignites the airFuel mixture required to power the engine.The ignition system consists of ignition coil, ignition plug, distributor, rotor and other parts.In the overall working mechanism of the engine, each one is assigned a specific function.When the spark plug generates the fireworks needed to trigger a fuel explosion --Air mixture, the dispenser assigns the spark to the appropriate spark plug.12-powerThe volt battery used in the machine is often not enough to trigger the spark needed to promote the explosion, which is where the "ignition coil" appears in the picture.It will Battery 12-The voltage power required to generate the spark is 40 kV.In other words, it is an induction coil that converts the relatively weak power in the battery to a huge power equivalent to 40g, resulting in sparks that ignite the airFuel mixture in the ignition system.When the contact circuit breaker is closed, the current of the battery begins to accumulate and lasts until full load is reached.Once full load is reached, the contact circuit breaker will open and generate high voltage sparks.If there is no ignition coil, the 12 v DC battery on the vehicle is useless, so a small amount of power is not enough to produce the spark needed for the explosion.While some of these coils rely on a resistor to reduce the voltage, others rely on a resistor wire or an external resistor to facilitate the reduction of the voltage.Basically, the ignition coil consists of two coils, one on the top of the other.These coils are also called windings, the first is called "primary coil" and the second is wrapped around the primary coil, which is called "secondary coil ".The number of circles of the secondary coil is a multiple of the number of circles of its primary coil.The current flows through the primary coil from the battery, and in the primary coil, the current is collected together to produce the required Spark, which is eventually sent by the secondary coil to the dispenser.To ensure that a large amount of heat generated during this process does not harm the coil, the coil is filled with oil as a coolant.While some engine models are equipped with an ignition coil, each plug of the other models has an ignition coil.In models with a single spark plug, the dispenser is used to assign sparks to the appropriate spark plug.Among the various ignition problems you may face, the weak spark and the coil are not ignited by the ignition coil.To diagnose these problems, you can use the spark plug test or the spark test.This will help you determine if it needs to be replaced.
