- 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.
I watched this channel years ago. Nice to see you return!
A simple explanation. We’ll done. Thanks
ممتاز شكراً جزيلاً
Nice, Thnak you very much❤
absolutely no fat on this video, well done!
I understood this genius system from your great video I've been escaping this before
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?
Very informative video.
I love your videos great and simple way to explain it
Thanks for Appreciation
THANK YOU!!!!!!!!!!!!!!!!!!!!!
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.
very well explained, congratulations!
Good video.
an absolutely EXCELLENT VIDEO!!! perfect explanation!!!!! thank you!!! thumbs up and a sub from me! mike
Nailed it!
Nice simulation , what software is this ?
Thank you
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.
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?
From where did you get this video please tell
Very good, but this a HISTORY lesson of how it used to be done!
If you have a newer car.
The principles are still the same.
What rotates the cam shaft?
So the 2 blue arrows @ the bottom are connected ya?
Thx n pls reply shortly.
They are grounded. Not connected.
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.
The output of the secondary side of the coil is AC. Therefore, virtually passing through the capacitor. The electrons do not actually pass through the capacitor. However, the energy passes through by virtue of the internal electric field. It is an AC by pass when the points are open. The closing of the points resets the process.
People are so smart how do you even come up with this
Inductance also plays an important role for this system. If you havent studied EMF before go check it out.
It's been long time haven't uploaded
Sir pulsar wali distributor kese kam karti hai.plz explain.meri gari me pulsar CDI wali lagi hui hai
Can you teach me how to make ignition coil for motor bike 🚲🚲🚲
you mite have shown the post on the coil as positive and negativity witch wire go to neg.
What makes the cam lobe rotate at the beginning?
The rotation of the pistons via the camshaft. The cam lobe is connected directly to the camshaft
@@omareid2297if the spark plugs are used to rotate the pistons, how can the pistons be used to rotate the camshaft which in turn turns on the spark plugs? This seems like a putting the cart before the horse situation.
The starter gets the whole thing turning just like when you pull the string on a lawn mower you are turning the engine by hand
The starter rotates when the battery supplies voltage to it, via the key and an in-line solenoid (to handle the high current required). The starter when activated then engages the flywheel via mechanical gears. The flywheel is a large diameter gear bolted directly onto the crankshaft, not to be confused with the camshaft. The crankshaft with its offset pivot points is what the pistons are bolted to, but with the necessary rotational movement being achieved via piston rod bearings. It is therefore the crankshaft that makes the pistons move up and down when starting an engine (or back and forth for horizontal applications). Then, once the engine starts, it then becomes the pistons that force the rotation of the crankshaft, which is connected to the drivetrain.
Not all engines are designed exactly alike. What I'm describing is the most common application for these older gasoline engines that are becoming fewer and fewer. If you have a 1950 to 1980s era engine (roughly speaking) you'll find the video helpful.
Now to your specific question: There is also "linkage" (accomplished in various ways) between the much larger crankshaft and the separate and smaller camshaft. The camshaft has individual lobes that open and close the intake & exhaust valves for each cylinder. (The cylinders are the dedicated housings for the pistons.) The camshaft also via separate mechanical linkage causes the distributor shaft with its own lobes to rotate...hence the answer to your question after a few necessary diversions. The short answer would be that the starter motor is what first forces the lobe rotation within the distributor, but it accomplishes this through a series of other in-line components. After the engine starts, the starter itself is then completely out of the picture.
By the way, this was first taught to me in a small-town high school over 60 years ago.
@@omareid2297 you mean the rotation of the camshaft produced by the cam gears. The piston is inside the chamber. lol

starting sir meron ka dyn (Suse, Battery, Distributor , Ignation coil, starter motor) yan po pano po ba Diagram po yan
so while designing these such as ignitions to power automobiles, they didn't quite understand the entire principle mechanisms until decades later wasn't it. it's like electron microscopes allowed medical observations to what they were already doing.
it's the same video as 10 years ago
We are working on newer videos soon we will upload.
Newtn
Current in a battery flows from negative to positive, not positive to negative. This is a common misconception. To be correct electric flows from a negative ground to the positive side of the battery. All current flows are incorrect, otherwise a decent illustration.
Inwas watching a video on the resistors and they were saying that no matter which direction it flow it doesnt have consequence
@@jordyfortier4069hook up a battery the wrong way in a car and see what happens 🤣🤣🤣 the literal movement of electrons does indeed flow "backwards" negative on a power source should be called the positive if one thinks of positive as the one that gives and negative takes.
When getting especially technical (at least several decades ago) we discussed the flow of electricity as "hole flow", not the electrons directional force. And incidentally, WITHIN the battery itself--which you directly mentioned--the flow here would be from negative to positive. You might want to consider this anomaly.
Current is defined as opposite the flow of elections. You are correct electrons flow from negative to positive, but current was defined before we knew this
There is “conventional current” and “electron flow” both are correct when used in the proper context. Remember, it is all theory we create so we can analyze and create circuits.
*Promo sm*
The
I don't even own a car with an ignition system anymore
Cool story
Diesel power❤
Cute
Yes you do, unless it's a EV!
@@waynelangston863 Well....
Please remove background music
Finally a video with non-intrusive, pleasant background music that lets you think, and you find this objectionable?
Because this instructional video has no audio, If you prefer silence, simply hit the mute button. Problem solved.
Turn your speaker down assfuck
This channel is. Hacked it’s no more mine
why do they have to make this shit so complicated. thoes old engineers suck
