Why Do Engines Need 3 Piston Rings? Explained

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.

THANK you sir for uploading the video. My ears feel blessed to hear your voice.

[funnyvines]

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

[wfrrlhi]

This video is simply the best! So illustrative. Easy to comprehend and it answers every question. You get 5-Stars!!

[s.m.h.m]

Very comprehensive and well explained.

[TraumaER]

Whoever invented rings was a genius. I would have designed the piston system with a tight tolerance around the cylinder walls.

[oguzoner]

Very explained! You have prepared with nice animations, different from others videos, I like it👍

[peterlonter]

a very good explanation of rings problems . like and subscribed .

[leisuremechanist]

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.

[jay-peephillips]

This was very helpful and informative. Thank you

[salascarlosgerardo]

Well explained...clear lenguage. Thanks a lot by your time

[clementmwenewisi]

Very educative and l now know why engine power loss is on my vehicle

[onurgns]

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.

[princejallah]

I'm a mechanic this video help me a lot and i hope to watch your video at all time.

[yslee]

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

[SakthiVel-vmub]

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

[Spitfireseven]

This was an excellent educational video

[miriamvivo]

2002 honda accord se 169, 000 miles heavy oil consumption. Gonna try piston soak

[robertoudokrapf]

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...

Deatil technical information shared....thx

[giauscaesar]

This is an excellent video thank you so much.
