Sectioned 4-cylinder engine - rpm 

The fact that the engine reached 1000 RPM really felt like a car idling.

Really neat to see a real demonstration rather than one of those animated videos!

The years these engines go through this and more is honestly amazing. Thanks!

I'd like see a timing light on this display turned on and off different times..long live the marvelous marvel of the internal combustion engine, the engine that has driven the world to amazing heights at amazing speeds, with amazing results! We owe every achievement of modern life to this machine!

I can't imagine what happens in an F1 engine that reaches up to 15,000 revolutions per minute.

Amazing that the engine is working that hard and all it takes is regular maintenance to keep it going

Excellent video... Best sectional engineering cut through I've ever seen... Total respect guys.... Thom in Scotland.

Просто прелесть ! Наиболее наглядное пособие для учеников. Да и для водителей...

Not sure how I missed this one, this is an awesome video! Great work!!

Que coisa incrível, difícil acreditar que conseguem trabalhar a essa velocidade. E na verdade os motores vão além disso. É realmente fantástico.

Wow must say the sound is hypnotizing. Well done, it is beautiful work of art👍🏻

This demostration just blew my mind. It is absolutely amazing what engineering has brought us and the life span of engines (especially when properly maintained). Can someone explain to me the lights when the cylinder things hit smack the recieving part of the engine?

Thankyou for a great video. Your enging sound's great at very low rpm through headphones.

This is great! Despite the engine rotating backwards but it shows the principle.

Molto interessante! Bello vederti postare un video.

Wow! This just shows just how amazing it is that an engine works at all! Excellent demonstration, thank you! :-)

My head is reeling at the idea that almost every car I see has this happening but faster

Wow amazing thank you for making the video love it so much

That's very nice & good too see you again my friend, have a healthy /wealthy New Years also.

It needs some STP Oil Treatment 🐱👍🏿

Hi good i see you again thanks for your videos

Cool engine

Didn't see you in a long time!

that no. 2 cyl intake valve spring seem weak. but this is awesome!

Nice. This is better on a 60fps camera

I drive@ 1500 RPM, its amazed to think crankshaft @25 RPS and piston moving up and down 12 times in seconds😢, man these pistons hard working to make us happy

Nice!

the engine: Help where my oil??

What size motor is spinning that engine. Thinking of trying this set up

Love it!!

Bellissimo anche il contagiri d'epoca!

was there no adapter to fit that tach cable to the cam instead?

*Engine because so fast that it got caught lagging!* 💀 4:14

Nice

in a normal motor when it running at those rpms, almost no metal to metal is touching, there is in oil layer between almost all moving parts between the metals. Only metal to metal is the piston ring to cylinder walls. Am I right?

Nice example of 4cyl cut-away engine display. I can see you took some extra time to get it setup just right, including lighe bulb flashes for power stroke. What kind of car did the engine come from? For viewer's understanding of RPM rates: Most gasoline car engines run about 2500 RPM to 3000 RPM at highway speeds... so that would be about 50 turns per second. (ie 25 power strokes on each piston per second) If you have a 6cyl engine, that would be 150 power strokes+sparks for whole engine per second. RPM for many cars at idle/still may be 700 to 900 rpm, which is still turning fairly quick, as your video shows. Another way to look at it: if caris driving 60 mph (88 feet per second) at 2500 RPM in a car with 4cyl engine, then the gas used for each piston's power stroke is moving car fwd about one foot. (or 1/3 meter) For metric perspective: if 3000RPM gets a car with 6cyl engine to 120 kph (33.3 mps) then each piston power stroke (150/sec) moves car 0.22 meters. (22.2cm or 8.75 inches) Most 4-stroke diesel engines in pickup or truck will turn about 1800 to 2100 RPM at road speed... so that is 30 to 35 turns per second. If that is a V8 truck engine, you have 120-140 power strokes per second, and could be driving 60mph, then each cyl power stroke moves truck about 7.5 inches or 19 cm. Small gas engines like motorcycles tend to turn higher speeds, and may run 6000 RPM (twice as fast as car) near 120 kph... but could only have two pistons, which would be 100 power strokes per second, so a 4stroke 2cyl engine would move cycle about 33cm per power stroke. (aprox 1ft. which is similar ratio seen with car example above)

Where we buy this

Даже на замедленном воспроизведении при 2000 оборотах неразличимо глазу работа цилиндров.

Nice video, but please don't record at 10 FPS in the future

Rapid de meter 👏⏳😱

💙🙏

Now image that at 10k rpm

Tutorial!!!!!! Pleasce

А, например, ДВС самолёта или вертолёта можете хотя бы макет показать ?

Sir i am extreamly very sorry for do that

How did it not seize without oil?

The valves timing not correct or my eyes are confused🤔

cara que loco

Now do a compression test

Поэтому и лошадиные силы потому что звук будто конь скачет

Imagine um Civic si a 9 mil rpm kk

Hello sir

Вау😮
