- Engine Knocking is a very common occurrence in IC engines. It occurs due to the improper combustion of the air-fuel mixture inside the combustion chamber of the Engine. In this video, we explain why this happens.

This vato explained it better than 99% of TH-cam, thank you.
But this isn't knocking, this is pinging
thank you for making this video, you gave a very short and clear explanation
thank you, it's way more clear now !
Thank you sir
Much useful❤️
This is my first video from your channel.
Clear Visuals and a good presentation. Keep up the good work. Looking forward to more contents.
Add a few real life examples and funny animations if possible. Make it fun to watch and learn
Very useful for me
Very good video bro keep it up
Thankyou so so much sir good class
Really well explained, I liked the animations!
Dear Daniel, thank you for your feedback. You made our day! We look forward to continuing to serve you well :)
Awesome !
Early combustion is called "pinging" it makes a slightly more metallic, or more high pitched sound, it can be solved if its not really severe by using high octane fuel (this is what its for, not performance) knocking is caused by worn bearings, like the drive shaft bearing becoming oval shaped and so the drive shaft hits either side of that slight oval shape worn into the bearing, creating a knocking sound, ot pretty much means the engine needs to be rebuilt.
Knocking sound can also be caused by stuff to do with the rocker arms, if the engine has those anymore
Also severe carbon deposits on piston headset come in contact with the head is a possible culprit no? But yes you nailed it
good job
Thanku sir
Thankss:) Just stared with CHE101
Lol I found you

This is plain wrong. What you described is NOT knock, but pre ignition. Knock happens when parts of the air fuel mixture ignite due to the pressure increase outside of the flamefront of the spark, resulting not only in uneven burn, but in a (supersonic) detonation instead of the (subsonic) deflagration the engine was designed for.
Pre ignition is ignition (of a deflagration) before the spark plug fires, so there is no supersonic pressure wave.
Google se chapa kya? Hahaha, me IIT se hu
@@crazify8887 tho mu mae le na
HERE i.e VIDEO, GIVEN WE WANT TO DECREASE KNOCKING, USE TO DECREASING THE INTAKE MANIFOLD PRESSURE. IN THIS CONCERN I THINK PROPER ATOMISTION OF GASOLINE PARTICLE IS NOT OCCURS. AFTER THAT RICH COMBUSTION CONDITION IS DEVELOP. WHICH INCRESE POLLUTION.
Mere teacher ne zyada ache se samjhaya. Me IIT se hu na isi liye
Main bhi tha
What is the difference between pre ignition and knocking ,?
What is described here is pre-ignition.
Hot spots in the combustion chamber light off the charge before the plug fires; the plug fires and the flame fronts collide. An area that is glowing hot is required, such as a carbon deposit, ot a sharp edge in the head casting.
This is called pre-ignition and id usually inaudible. Look for the center of the piston to be melted or blown out and it normally affects one cylinder.
Detonaton is literally an explosion inside the chamber.
The fuel charge is ignited by the spark and the flame front progresses across the chamber.
Part of the charge in the far reach of the chamber reaches it's auto-ignition temp and literally detonates instead of jurning smoothly and is very audible. Damage is seen as the edge of the piston melted and destroyed down the side into the ring lands, which are destroyed too.
If detonation occurs in one cylinder, look for a lean mixture to that one cylinder.
If detonation occurs in multiple cylinders or in all cylinders, look for excessive ignition timing, low-octane fuel, or a lean mixture across all cylinders.
My Hyundai is doing the same.
Can improper installation of spark plugs cause engine knocking?
yes!
watch 2 ads and then have this incomplete concept video. TH-cam is killing
Tmkc
Sri back Fireing what sir
Heh. "Stay tuned" in a video about engines.
Who came from psg automobile like😁
Tere lecture mein full stop kyu ni hai...first learn how to pause while giving lectures
U have to show how to fix it...not only talk to much...
This video is about what engine knock is boss, not how to fix it. No shit he’s gunna talk a lot. I sure hope he does when explaining subjects. Maybe google how to fix engine knock, might find a video more you’re area boss.
Weird how through the video his indian accent slowly kicked in yo
Instead of learning something new or how this video has helped others clear their doubts, all you can deduce is his change of accent. You must be one of those SJWs and must be having some liberal arts degree.
@@kartikeyasingh1907 No, I'm actually very racist, hence why I ridiculed his funny accent.
@@prosaic.7944 Still. Being racist is fine. But one shouldn't be such a fool to ignore the information provided over an accent. It's natural that different people sound different.
@@kartikeyasingh1907 Wow, you're so right. I watched the whole video, listened to him and realized that his fake accent slowly faded away and made a joke about it; I must have ignored what he said.
Sad really, having an official language, but not being able to pronounce anything properly.
Thank you sir
