How Ignition System Works | Explained with Animation, Wiring Diagram, and Parts Overview

The ignition system is a crucial component of any gasoline-powered engine, providing the high voltage necessary to ignite the fuel-air mixture in the engine's combustion chambers. In this video, we'll explore the inner workings of the ignition system, including how the ignition coil works, the components of the distributor unit, and the role of the spark plugs in the ignition process.

The purpose of the ignition system is to generate a very high voltage from the car's 12-volt battery and send it to each spark plug in turn, igniting the fuel-air mixture in the engine's combustion chambers. The ignition coil is the component responsible for producing this high voltage. It's an electromagnetic device that converts the low-tension (LT) current from the battery to high-tension (HT) current each time the distributor contact-breaker points open.

The distributor unit is a critical part of the ignition system, consisting of a metal bowl that houses the contact-breaker points, rotor arm, and a device for altering the ignition timing. The central shaft of the distributor is usually driven directly by the camshaft or, sometimes, by the crankshaft. The distributor cap carries the high voltage from the coil to the spark plugs, which ignite the fuel-air mixture.

In this video, we'll provide an animation that demonstrates how the ignition system works, from the battery to the spark plug ignition. We'll also show an ignition system wiring diagram that illustrates the connections between the battery, ignition coil, distributor, and spark plugs. Additionally, we'll give an overview of the parts of the ignition system and explain how each one works together to get the engine started.

By the end of this video, you'll have a comprehensive understanding of how the ignition system works and how to troubleshoot common problems. Whether you're a seasoned mechanic or a novice home mechanic, this video will provide valuable insights into one of the most critical systems in your car.

Excellent video! Simple, straightforward, no blah blah, shaky camera, etc. Nice job.

[Mihacappy]

I watched this channel years ago. Nice to see you return!

[pjyvqlm]

ممتاز شكراً جزيلاً
Nice, Thnak you very much❤

[zjtr]

A simple explanation. We’ll done. Thanks

[yannickkay]

I understood this genius system from your great video I've been escaping this before

[YourLocalCommunist-gf]

I love the music and how the animation is similar to your videos from long ago!

I have to ask, what happened that caused you to stop posting for so long?

[kieranstone]

absolutely no fat on this video, well done!

[galinstan]

Sir, great video. I love the clarity the animation brings. How about one on a magneto ignition system, or a capacitive discharge system.

Lastly, I would love to see one focused on the coil, e.g., internal connections, output waveform, output frequency.

[BrianHunter-nipn]

This really helped me, thank you very much for posting.

[stevekasera]

Very educative sir, how can I add electric flow to electrical components such as battery and power converter, do I need to have any special software?

[Pako_equis]

I love your videos great and simple way to explain it

[i_saurini]

Nice explanation though I wished it was including also starter, alternator, engine starting. I'm looking to find out the start problem I have on my vehicle.

[mkepler]

an absolutely EXCELLENT VIDEO!!! perfect thank you!!! thumbs up and a sub from me! mike

[johnrockley]

Very good, but this a HISTORY lesson of how it used to be done!

[MrHernanliom]

Nice simulation, what software is this ?

[sevalkalai-]

From where did you get this video please tell

[Seldomheardabout]

Bro the capacitor or condenser just prevents arcing when the contact points break by providing an easier path than air does, until the points are far enough to stop arcing (also when the capacitor is full im assuming). The cam head is just timing the spark plug fires. Took me a few minutes.

Sir pulsar wali distributor kese kam karti hai.plz explain.meri gari me pulsar CDI wali lagi hui hai

[freshyip]

So the 2 blue arrows @ the bottom are connected ya?

Thx n pls reply shortly.
