Who ever made this video, deserve a medal🏆🥇🎖 and more

[@2AMech]

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!

[@sandronovecento76]

Absolutely the best vid about the knocking!

[@ctsteve1967]

and pre-ignition that you cannot hear will crack your rings very quick

[@caruser4]

I've never been this pumped about engine knock

[@231mac]

Haha!

[@Dabber234]

Almost forgot it was ruining my engine lmao!

[@stilldontknowmyname2494]

Background music plays a role! ;-)

[@Lisa-nz9bq]

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!

[@sinanalhamdani9316]

The best explanation video I have ever seen about the topic.
Thanks a lot

[@zuten88]

What a video! The music and the cinematic editing is pure genius!

[@Bleeper168]

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

[@sillyKit]

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

[@gayrunnycumstain]

we should be knocking boots

[@rextevar8582]

Xdd hahahaha ISO

[@tizcoloko]

Xdd by text searchs and voice recognitin, truly creepy i a watch trangender videos.

[@BeautifulWorld2001]

explains the difference between knocking and pre-ignition..thanks keep making such great videos

[@aloksingh-yp3gc]

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.

[@justincase9638]

Wow that was a spectacular demonstration - Now I know!

[@iftekharrousseau493]

too good to let everyone understand, I suggest every engineering students to watch this video for understanding very easily the knocking and pre-ignition

[@BrennoAlves15]

So simple! The best vid about knock and pre ignition i've ever seen.

[@yaronvenddeta1210]

Hi

[@Jays22b]

Nice and clear to understand. Good work. Im going 1 step cooler with mods soon after watching pre ignition .

[@stark5000]

Amazing..loved it, timing of the music and the animation is just awsome. Sharing this right away.

[@KapilSolanki]

Comments to this video shows popularity and importance of this video... A huge thanks...

[@AdhamNafea]

Please do more of these videos..amazing....Thanks alot

[@khiemthongminh]

Beautiful video about engine knocking.

This is a very explanatory video, the best I've seen on knocking and pre-ignition. please permit me to share this with others

[@boostedbuiltgarage]

Animations are on point👌

[@wamanwell-being2470]

Simply amazing....Waiting for more such videos

[@premgupta3627]

Combination of video and music knocking my brain EXCELLENT WORK

[@swami200]

Amazingly explained

[@Steve-mu4oy]

Outstanding video! Thank you!

[@francoismorin6806]

Thanks you to made this free video just for the knowledge !!

[@Rippey574]

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!

[@HorsepowerHouse]

Michael Rippey and yet you are nitpicking as well. Sighhhhh

[@oc2phish07]

Brilliant. Accurate, clear and easy to understand.

[@zakery6390]

Good explanation & nice animation! Appreciate the video.

The best video ever, thank you

[@jagadeeshbabuk7914]

Fantastic video with super bgm.

[@dariomendoza1518]

changing tp Premium gas .SHELL in my experience litterally solved my preignition ,thanks for the video!!

[@gregorysampson8759]

Great video thanks! I have a top of the line kohler that knocks like it's made out of marbles.

[@KapilSolanki]

Very carefully explained... Thank you so much.

[@dhivakarankarunanithi123]

it is very clearly understand than the other explained

[@Turboboob]

best vid on the subject, thanks

[@Bigblackee3]

Invaluable help. Very informative. ❤

[@edigabnsprabhugoud1128]

very good to understand the ignition system technology for students and mechanics. thanks for your technical co operation.

Melhor vídeo . Melhor marca de velas de ignição que existe .

[@codyjames8424]

Great video! Learned something today. You should do a video on how to read your spark plug for tuning!

[@entrepreneur785]

Awesome video animation

[@vedprepteachingacademy]

Nice Video...Keep it up....

[@qayumbacha6736]

Thanks for viewing knocking and pre-ignition best video

[@AmitJayant]

Fantastic explanation.

[@tariqraad6926]

this was beautiful I like it 👍👍

[@mrsemifixit]

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?

[@vinay_bharti]

Great experiment videos

[@ilyaspatel2413]

Awesome video and music is mind blowing

[@julianamado9878]

Woww, amazing video 👌🏼

[@YZFMANIAC08]

thanks a lot.... a highly beneficial video

[@nawarbakree5005]

Hello...
I have a car type Kia 4-cylinder engine size 2400 GDI, I use long-type ignition plugs which are recommended by Kia
My question is: Can I change spark plugs from long to short -type to get rid of the knocking or detonation problem?
I've already installed spark plugs (short- type ) and got rid of the problem, but does have a bad effect on the engine later ..?
Thanks

[@Problems-qp2ud]

Amazing engineering

[@obedm.6627]

Prefect illustrations!

[@amolpogake5910]

Its very helpful video to understanding the concept
Thanks 🙏

[@xtra1234]

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.

[@WatchoutNSG]

Great amazing video very imformative.

[@vaibhavpatelnuclearengineer]

Mind blowing video on knocking.

perfect video

[@KevinBasilMagnus-sy7rm]

SUPER THANKYOU NCK🎉🎉🙏🙏

[@adarshsharma3710]

nicely explained

[@mmganesh6087]

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 .

[@THACHDUONGVLOG]

Hi you are very pleased to meet you

[@gestech_1774]

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

[@DevanKalaichelvan]

this was so beautiful to watch an very informative.. thanks guys.... even my bike uses NGK spark plugs :D

[@JimmyHondaRacing12]

Very cool! 👍👍
