Who ever made this video, deserve a medal🏆🥇🎖 and more
omg, i finally understand knock vs. pre-ignition! whoever made this animation and video, i hope you paid them very well! thanks for the excellent visual explanation!
I've never been this pumped about engine knock
Haha!
Almost forgot it was ruining my engine lmao!
Background music plays a role! ;-)
Yooo that’s so creepy my engine has been knocking and i was planning to look that up, now all of sudden this video gets recommended to me! They’re watching us
we should be knocking boots
Xdd hahahaha ISO
Xdd by text searchs and voice recognitin, truly creepy i a watch trangender videos.
Absolutely the best vid about the knocking!
and pre-ignition that you cannot hear will crack your rings very quick
What a video! The music and the cinematic editing is pure genius!
The best explanation video I have ever seen about the topic.
Thanks a lot
explains the difference between knocking and pre-ignition..thanks keep making such great videos
Pre ignition is a spark plug timing related problem and not related to ignition of fuel inside cylinder early.Though it can be associated in combination to it.
too good to let everyone understand, I suggest every engineering students to watch this video for understanding very easily the knocking and pre-ignition
This is one of the best animations and informative videos I've ever seen. Thank you! (Curious to find out what caused this noise when a couple of customers' vehicle broke down in our driveway at NAPA. Engine is seized up. No oil or coolant) but still knocked instead of slight tapping noise
Great video and explanation!! I Love the visual effects it makes it so much easier to actually see how the moving parts work together. Thank you for the video!
Comments to this video shows popularity and importance of this video... A huge thanks...
changing tp Premium gas .SHELL in my experience litterally solved my preignition ,thanks for the video!!
Wow that was a spectacular demonstration - Now I know!
This is a very explanatory video, the best I've seen on knocking and pre-ignition. please permit me to share this with others
Amazing..loved it, timing of the music and the animation is just awsome. Sharing this right away.
The best video to understand knocking
Best Video about Knocking in the Whole World
Combination of video and music knocking my brain EXCELLENT WORK
Outstanding video! Thank you!
Impressive video! You even animated the scavenger effect with the valve overlap! Looks like you went with the 8*btdc ignition to. Correctly animated the lean pocket on the top of the piston and appears you even left in some of the combustion gas from the previous cycle, very nice! Wish you would have thrown in some reversion, and that ring gap lol; also smack your builder for not offsetting the primary and intermediary ring.. Yea they move and rarely settle in the original offset, but it makes me sleep easier seeing it that way :-p Don't let any of my nitpicks deter you, this is by far the most accurate animation I have yet to see. Keep up this superior attention to detail!
Michael Rippey and yet you are nitpicking as well. Sighhhhh
Good explanation & nice animation! Appreciate the video.
Invaluable help. Very informative. ❤
Brilliant. Accurate, clear and easy to understand.

The best video ever, thank you
Please do more of these videos..amazing....Thanks alot
Nice and clear to understand. Good work. Im going 1 step cooler with mods soon after watching pre ignition .
Its very helpful video to understanding the concept
Thanks 🙏
it is very clearly understand than the other explained
Ashe - To Tha Top (Featuring Frequency)... Fantastic explanation.
Excellent video. Loved it 🔥♥
thanks for the graphic makes it very easy to understand
So simple! The best vid about knock and pre ignition i've ever seen.
Hi
Thanks for viewing knocking and pre-ignition best video
Amazingly explained
Easy to understand and nice back ground music
Animations are on point👌
some high quality detailed animation, thanks.
With knocking ,the initial ignition of the mixture is initiated by the spark plug. Caused by the combistion pressure and induced heat ,a spontaneous combustion of the mixture occurs. Asecond almost "parallel" combustion inside the cylinder is the result. When both flame fronts hit,intense high-frequency pressure waves are produced . These pressure waves create characteristic metalic "ping" sound,and cylinder pressure increases dramatically . Konocking combustion can lead to pre-ignition because of high combustion temperature
Best explation ever aside animation effects..
I give 1000 likes if have
The timing itself can cause this as well. Basically, its getting ignited before the spark plug ignites causing the compression stroke to be slammed on its way up before reaching TDC.
Simply amazing....Waiting for more such videos
Amazing video mujhe to iss video se bhi zayada is k upr lag hua music psnd aya h
Great video thanks! I have a top of the line kohler that knocks like it's made out of marbles.
Mind blowing video on knocking.
Very carefully explained... Thank you so much.
Top notch graphics and explanation.Make more videos on automobile
Very helpful thanks.what a editing.
Beautiful video about engine knocking.
very good to understand the ignition system technology for students and mechanics. thanks for your technical co operation.
Simply awesome!! Very informative presentation. Thank you!!
So I advanced my distributor all the way and floored my car! The video is new and on my page.
Awesome video animation
The background music is osm!! 🔥🔥🔥🔥 It gave me goosebumps
SUPER THANKYOU NCK🎉🎉🙏🙏
Awesome demonstration. One thing I’m unclear about, if ignition timing is too advanced, how does that create knock? Is it because spark plug fires too early before tdc and the heat as the piston is traveling up can ignite another spot at the same time?
best vid on the subject, thanks
Excellent video. Thanks!
Great video! Learned something today. You should do a video on how to read your spark plug for tuning!
this was so beautiful to watch an very informative.. thanks guys.... even my bike uses NGK spark plugs :D
best video ever seen
Excellent video!!!
Fantastic video with super bgm.
best video for knocking..........loved it.
nicely explained
in case of detonation you basically have the combustion process accelerated because of the additional spots where fuel starts to burn so similarly to pre ignition the peak pressure is going to be before it was intended resulting in a higher peak. Preignition also makes a pinging sound without the wave fronts colliding.
the wave front’s colliding theory seems hard to understand. basically the fronts travel at less than 1 m/s. and collision between them doesn’t seem relevant but collision between sound wave fronts might be. These travel at the speed of sound and bounce off the walls. the sound waves should have very low frequency. Doesn’t seem a problem anyway. Besides there are double spark plug engines, that wouldn’t be possible.
Perfection explanation 👍🏻
nice video. ...
pre-ignit got it...
knocking have to ...
Amazing engineering
Great Video,Thank you
Very very nice and informative!
Great experiment videos
Great Demonstration.
this was beautiful I like it 👍👍
Detonation (knocking) is caused by the sudden vaporization of atomized fuel in the combustion chamber, the volume ratio of which can be as much as 30,000/1. If the fuel is fully vaporized before entering the combustion chamber detonation does not occur, even when low octane fuel is used.
perfect video
Great visual effects
Hi you are very pleased to meet you
Loveliest demonstration...
Awesome video and music is mind blowing
*Gran video de lo mejor , podría decir que el knock es el encuentro de las dos ondas expansivas ,una provocada por la chispa de sparkplug y la otra por un punto de carbón dentro de recamara*
Thanks great video
Great Animations, Impressive :)
Useful and learning video
Thanku NgK
thanks a lot.... a highly beneficial video
Amo essa função de mecânico é lindo ver como as peças trabalhar e tem sua função
The animation details were apt!!
This animination is 💥💥
very good and
Thanks you to made this free video just for the knowledge !!
3.45 what is " correct tightening torque" ? is it how much we tighten the spark plug when we put back after cleaning the spark plug? ( which is something we can do easily.. tighten less rigidly ) or is it something that a mechanic has to do in the head of the cylinder ?
this animation video is good...clear .
Amazing.
Fantastic explanation.
this video helped me pass my exams
Wow, what an animation.
Knowledgable video
Melhor vídeo . Melhor marca de velas de ignição que existe .
Good info and animation..Thank you
Outstanding
this video was epic and informative..thank you
