- A piston ring is a metallic split ring that is attached to the outer diameter of a piston in an internal combustion engine. They are typically positioned in grooves or slots on the piston itself. These rings serve as a sealing mechanism between the piston and the inner walls of the engine's cylinder.
Piston rings ensure that the combustion chamber, where fuel and air ignite to produce power, remains sealed during the engine's operation. This seal prevents any gas from escaping or oil from entering where it shouldn't be. This sealing action is essential for engine efficiency and performance.
Automotive piston engines typically have three rings per cylinder. The top two rings known as compression rings, are primarily for sealing the combustion chamber. The bottom ring known as the oil control ring, is primarily for controlling the supply of oil to the cylinder wall.

This video is simply the best! So illustrative. Easy to comprehend and it answers every question. You get 5-Stars!!
It's a good video relating to the engine performance. It increased my knowledge and gave me a lot of information about piston and piston ring. Good job and thank you
a very good explanation of rings problems . like and subscribed .
Very comprehensive and well explained.
THANK you sir for uploading the video. My ears feel blessed to hear your voice.
This was very helpful and informative. Thank you
Wow complete guide on Piston ❤️
Very well explained nice work
Well explained...clear lenguage. Thanks a lot by your time
A fantastic video. Thanks!
Very explained! You have prepared with nice animations, different from others videos, I like it👍
Good information, thanks for sharing
great informative video!
This is an excellent video thank you so much.
Powerful explained
thanks for this good explanation
That's so good explained ❤
Useful content Boss....a clear knowledge of this saves not only the vehicle oners wallet but also the environment in the longer run👏
This was an excellent educational video
Well explained keep it up
Brilliant video.
Thank you for this video its explain everything
I learn a lot from this video
Well explained! However, a well-designed and maintained engine and its piston rings can easily last 400,000km/250,000 miles without opening the engine without the engine's oil consumption having increased significantly.
Very much educative
I have a vw tdi that's just hit 300,000 miles. That's just with regular oil changes every 10,000 miles. I'm gonna try and get it to half a million miles. 🤞
Totally agree. The estimate of 100 000 miles is false IMHO...Frequent oil changes with quality oil will greatly help improve longevity.
@@dmatteo1609changing oils at 10,000 miles don’t know how you lasted that long but if you continue it might not.
I'm at 430,000km on my diesel and blow by showed up just recently.
Thanks for explanation. All stuffs is good.
Interestingly educative.
Nicely explaination
Best explained ❤
Deatil technical information shared....thx
Whoever invented rings was a genius. I would have designed the piston system with a tight tolerance around the cylinder walls.
Thank you your video.
Very educative and l now know why engine power loss is on my vehicle
Thank you!
Great video
OLÁ. 8/12/23. CREIO TER SIDO O MELHOR QUE VI NA INTERNET ATÉ HOJE. Poderiam ter mostrado o lado de montagem dos setores de aço em relação à lateral da canaleta do anél de óleo. Devido ao processo como é fabricado o setor de aço não é perfeitamente plano. Como a função é de "regular" a quantidade de óleo para os anéis de compressão o erro de montagem pode provocar aumento do consumo de lubrificante ou insuficiência de lubrificação. ABRAÇOS...

I love this channel
Good job 👍
Good job sir
Thanks a lot.
I am sakthivel from india. I'm studying marine engineering. I am really admiring of your videos .Could you try to post video related to ship engine side.
Your video are really fabulous I ever seen
Can you do a video about the alignment of piston rings European car if is possible a place where to place orders.
It is very important engineering and hard to do it with all pressure heat and imagining bores widen during heat . Also oil need to lube the walls without excessive oil consumption.
In case mechanic upper 2 ring fixing a positive direction...what simtum showing engine starting ... please tell me
If compression, PCV and valve seals are ok, I think it's oil rings that are bad, or could it be something else?
How about broken rings? I have found a few, with deep score in cylinder wall.
Very nice
good explanation of piston rings #👍👍🇵🇰
Superb
I had a Nissan Sunny from the 80’s. The engine lasted more than 450,000kms without increased oil consumption. Those early days Nissan engines were bullet proof
The early Datsun roadster engines had pistons with 5 rings.
They also ran lower compression
Now Nissan ranks near bottom middle of all car manufacturers.
It's helpful
OLÁ. 12/12/23 - Assisti novamente o vídeo. A realidade é que o assunto em pauta é imenso. Se examinarem o anél de óleo "SIMPLES" por Vós demonstrado no mesmo vídeo poderão constatar que a montagem do com setores de aço por Vós apresentada é incorreta. Eu teria mais algumas informações mas continuo afirmando que é o melhor que vi na Internet. ABRAÇOS...Roberto Udo Krapf
Rc race cars don't use for high pressure waves they still have lil grooves which act like a seal but some don't have rings
How big is the gap in the split ring?
Great.🎉
I'm a mechanic this video help me a lot and i hope to watch your video at all time.
Nice
It is a good video
Can you make another video about how you set the piston ring because I saw different videos but it’s not similar tell us how the right way to set the piston rings thank you.
there are mostly 2 ways of doing it.
most typical is with 3 piston rings.
Many of the service manuals on newer engines say to put all 3 ring gaps at 120degrees from eachother.
and another way is to put the gaps on opposite side of eachother.
i personally put the ring gaps at opposite of eachother.
2002 honda accord se 169,000 miles heavy oil consumption. Gonna try piston soak
Use Top Engine Cleaner, I think it's AC Delco brand. Comes in a metal can. Honestly the rings might be too far gone, but worth a try. Regular oil changes and carbon cleaning are key. I had a 99 and it drank oil like water, I topped the oil at 1000 miles and at 2000 miles id change it. Those old accords just never quit. Thing ran and ran, I worked with a guy that had one he ran low on oil for two weeks, no knock topped it up and it kept rolling.
Plz make videos of smvt as many as possible

The rings act as a seal between the combustion chamber and the crankcase. However I don't see how this can provide a good seal when there is a clearly a gap on each of the rings. Wouldn't the gasses pass through this gap and leak out?
On assembly you stagger the ring gaps so they do not overlap to eliminate blowby.
The gap looks big when the piston is outside the cylinder, but when installed the ring is compressed and the gap becomes very small - about 0.25 to 0.50mm and it almost disappears when the engine gets hot. A little gas passes through the gap but the quantity is almost negligible.
It's called ring in gap. If set properly and the 3 different rings staggered 120 degrees apart it will perform as designed with very minor compression loss or blow by. All internal combustion engines are designed and have been for decades to operate this way
Don't be tired
Nice way ❤
أحسنت
Am now interesting to join you
Sometimes I also use ring on my piston, to make it more durable
Man...
What piston?
Não entendo como os anéis de compressão recebem lubrificação, visto que a saída de óleo se dá no anel inferior. Poderia explicar? Obrigado.
Great brain desert 👍
That was my best key . my professional area
So why not 4? or 5?
You never mentioned how critical the ring gap is
There have been many engines that use 4 rings.
In my country it carry 5 u forget to check the oil ring
❤❤❤
Hi
except on the honda insight which has the most mpg of any car ever.
🎉
JDM Pulsar and Sunny have 1 compression ring, whereas their european twins have 2 compr rings in GA and QG engine

My engine has 3 compression rings and no oil ring!
well the last one is oil ring. some older engines had piston rings all the same.

How work piston rings in telugu
Internal Combustion Engine is going the way of the dodo bird.
Electric motors have none of the problems and complexity of ICE.
the problem with EV is battery there heavy and low capacity while Electric hybrid have capacity and lighter
Ok but it’s expensive, horrible for the environment and you might get bullied.
Also dodo birds didn’t deserve to die.
Good luck putting out those Lithium ion battery fires. Google "Dutch Oven", half a billion reasons why Lithium ion battery EVs will be the doom of humanity and planet earth. Don't get me wrong, EVs have huge potential, but that potential is impossible to realize with current battery tech. Until battery/super capacitor technology or some other electrical energy storage technology is good enough, EVs are worse than ICEs from an overall practical standpoint in every way.
They're actually quite complex, enough so that most average people can't work on them. There's also the issue that grids aren't made to power all of the cars on earth yet and are no where near enough.
I can guarantee u have never worked on a car gas or ev much less worked on any sort of electrical diagnosis in any field
thanks,
Hi
