It's hard to imagine air moves in and out at that speed in sync.
piston do the air suck at a time. so air can be sucked by piston so its kind of easy to enter air through the valves
even more unbelievable is that the crankshaft is spinning twice as fast as the camshafts
Yea

1. It's amazing how fast the spring can rebound.
2. I am amazed that cam lobes don't wear down faster than they do. Even with oil that is a lot of friction.
You know if you hit water really fast with your hand? It feels like you're hitting a solid? I'm thinking that the cam lobes are hitting that other oil covered part so fast that the oil acts like a solid and the two part don't really touch at high speed. Could be bro science though 🤣
That's why the metallic sound from the start disappears too
@@CabinetFramingUK This is exactly what happens! Good observation and imagination! Slow movement can be more wearing than fast movement.
@@CabinetFramingUK 100% correct. thats why the only part that matters is the film that the oil leaves behind as it is NOT compressible and at this thickness it is basically a solid
@@CabinetFramingUK bro you're a fucking genius
Been a mechanic for nearly 40 years and it still amazes me, how hard the internals of an engine work, without going bang, majority of people have no idea when they press that right pedal
That's why I fell in love with cars. At a very young age (I think somewhere between 6-10) I realized how complex and amazing they are. How big of a feat they are for human creation, even tho most Americans use one daily without second thought of what's actually happening.
And how they last for so long without wear. Saw an Audi A4 diesel engine taken apart with 820,000 km on the clock, the cylinders still had factory honing marks visible on them and the engine was in perfect condition, in fact it dyno'd at 5% more power than factory previously.
Watch at 2x speed to see overhead cams at 28k RPM
lol
Pure genius
Big smart
Big brain right here
Actually cams spin at half the speed of the crank so speeding the video 2x would only get you to 14k rpms.
The heat, impact, vibration... The fact that engines don’t come apart at the seams more often is a scientific marvel.
TidalWave Dan most engines don’t even reach 1/2 the speeds you see here. average redline for a street car is like 6500rpm.
@@gallardo20000 Most 600/750/1000cc class sportbikes are designed to be redlined 12-14k daily. Majority of these bikes last for years after heavy use which is a testament to today's engineering.

+idriwzrd well yeah but still
Formula One cars use compressed gas instead of springs to prevent "valve float" which is what happens when your engine is at such a high RPM, the valves can't close fast enough to contain the compression stroke and you lose power. So yeah, on very high revving engines, you'll rarely find springs.
+idriwzrd im surprised theres no valve float at this RPM.

Valve Springs at 14k rpm are like: That's too fast, we are spinning now instead of beeing a spring.
They spine to rotate the valves to prevent over heating. They are called valve rotaters
@@derekhightower1530 only on one side?
They exhaust and intake valve both were rotating. They dont have to rotate in a complete circle but they can move back and fourth with a small degree.
@@derekhightower1530 It has nothing to do with over heating. They rotate so that they reduce wear on the valve tips. If they didn't rotate they would wear out faster.

14K RPM? That is some strong valve springs.
scavengerspc this engine appears to have a valve return rocker. Another car love actuates it. It’s prevents valve float at high rpm by pulling back up on the valve once it has already been opened. I forget the name of this type of engine
scavengerspc it’s called a desmodromic valve setup
But wouldn’t each one be spinning at 7100 RPM‘s As the piston is traveling at 14,200 rpm’s
@@profblindserv no rpm is based on cam speed not crank speed. The crank is turning twice at fast. So at 14k the crank is spinning at 28k rpm
@@andrewsomma299 nope, rpm is always based on the crank, so at 14k rpm the cam is spinning 7k rpm.
Absolutely amazing!!! Thank you for letting us see that!!

The high-pitch scream occurs at 10k rpm, but the rest yea idk
Some one really needs to do this again with one of those 10,000,000 fps cameras, that would be a trip to see in slow motion, actually watching those spring go up and down that fast...
I was thinking the same thing, but then pondered, is seeing some thing that is going really fast, slowed down, really getting me any where, versus just watching it while it's going slow?
Terry Straubel I'd argue that it is. Acceleration and anything affected by gravity look completely different when at "hi speed slow mo." Think of watching someone run vs. watching someone walk; there are all sorts of details that are completely different.
Terry Straubel I've seen it in slow mo. I can't remember where though. It does indeed look different; the top of the valve spring goes up and down with the cam, but the middle sort of resonates back and forth like a slinky.
not quite 14k rpm but here's 8500 - just paste this after the watch? part of the url for a video v=WtqDHJDN79w (i can't remember youtube's standard reaction to posting links in comments)

Always baffles me that the springs are able to 'expand' quickly enough to keep up with the cams. You wouldn't think they'd be able to at that speed. Awesome.
Jonas Jonaitis not necessarily. Next choice can be desmodromic valves - uses Ducati.
David Sýs The desmo uses pneumatic valves
wolfy9005
Ducati do not use pneumatic valves. Not even in their MotoGP prototypes.
espibanez1 I agree completely.
espibanez1 Ah I was mistaken about the desmos valve train being pneumatic. What sort of pressures are they running to open and close valves in a purely pneumatic system? Surely a hybrid system would be more accurate from a timing perspective...
Could always increase compression ratio to keep power the same and reduce the typical rpms into a more spring-and-cam friendly territory. Not like they don't have the money, I should probably read the MotoGP rules for engines
I recently had a Gates timing belt that was putting my camshaft pulley off a half of a tooth, one way my 0-60 was really good with horrible low end torque, the other way lots of low end torque but it would actually slow itself down once I got to higher rpm accelerating. I ended up getting an OEM one and it solved all my problems. It astonishes how a smidge of a degree a camshaft can be off, make drastic changes to low end and high end torque, be driven a few thousand miles, and still not ruin a motor.
We once had an ex-MOD Landy with the 67 bhp 2.5 litre N/A engine and it ran fine. We fitted a new timing belt and found the old one was two teeth out!
Me: I'm so stressed, I do alot of work
Overhead cams: first time?
the engine is currently running at 14k rpm and normal car engines only go to about 7000 rpm
It's incredible that the springs and valves can keep up with that speed.
ever heard of valve float?
+Dany Labonte I think I actually noticed a bit as they were ramping up in speed. Particularly on the right, valve seemed to stay open for a short while. The second spring helps with that though, as both should operate at a different resonant frequency, which is a large contributor to valve float.
+DanTheSasquatch I like Ducati's solution more....just have a second rocker arm close the valve instead of a spring. You can reach way higher rpm's without valve float. Look up ducati desmodromic valves. Drawback is valve gap adjustment is a b*.
+kees ketsers Will do! I'm sure there are better solutions, bit I work in aviation and getting any "new" ideas is almost blasphemy. God help you if you actually want anything to become certified...
What's even more impressive to me when you realize how fast pistons must be moving in this engine, imagine the g-forces experienced by those engine components. Brutal.

Lol
LMAO I'm dead,
Those springs have a tough job ... 😯
when and if you do get valve float it acts like a limiter, and the engine will not achieve higher rpm. Dependent on the deck to seat distance, sometimes you do have valve incident (valves hitting the top of the piston), but usually, the torque curve is such, that a trained driver, builder or someone who understands red line on a tach WILL NOT take a motor to the point that it floats the valves,
so does my drive shaft.
Sub to pewds, report T-Series!
Yeah... it's a good thing they are inanimate objects that don't think or feel anything.
@jesus jones ...lol
The internal combustion engine is an absolute engineering marvel and this video proves it every time I watch it.
So that's why lightweight valves are important...Hard to believe the spring actually maintains control at that speed. Incredible.
SPRINGS ARE MADE OF TITAINIUM AND KRYPTONITE
The lightweight valve cools worse, as a result of which it wears out faster, and burns out more often.

Is this why I have to check my KTM's valve clerance every 5 seconds?
BULLSHIT YOU SHOULD CHECK EVERY 4.8 SECONDS
Kinda. The valve seat wears out, so the valve tries to go deeper into the guide until it's up against the cam constantly and the valve never closes. On a low RPM engine, it just makes it hard to start and it doesn't run quite so perfectly. On a high RPM engine, the stem concentrates its force on the center of the valve bucket and can split it. Head is toast. Another more common problem is the poor clearance makes the valve resonate and it eventually breaks off. Engine is toast. Look up "Dropped valve."
