Inside the Cylinder

[Dillon1108]

wow how the hell does this happen like 200 times a second in normal speed? pretty amazing

[memadmax69]

No valve overlap, so the engine was most likely naturally aspirated.

[marek0086]

@memadmax69~ no overlap??.... they cut the footage before we get to see any overlap!

[memadmax69]

@marek0086 Yea, I was tipsy when I made my post, and failed to realize that it was just the same thing looped three times lol.

[mhmyup1]

I'm surprised no one has typed "car porn" yet.

[goreziad]

this is probably not real. if it is real, this engine have a fuel effeciency of about 5% or lower

[briggsquantum]

@goreziad You are the second smartest guy on this thread. You're right, it's a fake, completely and utterly. Which makes all the others trying to describe it as "naturally aspirated" or what kind of camera was used, or how often they changed it (!) seem foolish.

[MasterChris117]

So awesome

[skeesh1285]

awesome video



[Pianobuggy]

Amazing video! I've never seen something like this before!

[zedwid1]

Easily the coolest video I've ever seen.

[dimitrismpower]

amazing

[fuckingkidsthesedays]

dam this is slooooooowwwww right down

[McSwaggerWagon]

this is beter than national geographic's inside the womb show...

[jrg8008]

@McSwaggerWagon Yeah, but not the outside the womb one. ;-)

[Danny211897ike]

I WANT TO SEE VALVE OVERLAP..... DAM

[JasonMann8]

thats fucking sick

[D13fledermause]

Doesn't seem like they showed the exhaust stroke to me, might be wrong.

[Trendyrapslut]

@D13fledermause yea what the fuck is this shit

[cobrachoppergirl]

Its amazing that such a primitive and unsophisticated air pump, as far as air pumps go, powers and moves millions of people around the world, and so little conceptual improvement has actually been done to replace it with something... effectively better. I think jet engines and turbines move air through a lot more effectively but apparently they are not nearly as efficient to be usable in motor vehicles.

[Starbreaker666]

Valve float!!! thatst he fire around the intake valve.. sucking in oxygen. This was a supercharged straight 6 IIRC.

[MonkeyWithAWrench]

i wonder what that would look like with gm swirl port heads...

[wraith01mg]

This was most likely done using a twin spark engine with one plug removed and a toughened fibre optic Camara probe connected to a high speed recorder. This would account for poor burn in the cylinder. Could be wrong about the twin spark idea could just be drilled hole with thread. Short clip may be the result of the Camara failing under very hostile conditions.

[mmschweizer]

This is great. Was this carbureted? It's interesting how the poorly atomized drops bounce off the back of the valve and atomize. It really shows how the shape of the BACK of the valve can have an effect on the performance of the engine.

[9b8]

That engine has poor fuel atomization! Anyone notice the "ring of fire" effect around the intake valve during combustion? Detonation?

[EthansRidealongs]

suck squeeze bang blow.

[kloveless82]

Sweet

[staytruestayfit]

amazing job on the video. always wanted to see that

[Sneezewart]

Wow, i've always wanted to see this.

You can even see the plug firing!

[carpetmonk]

too cool

[hubbleISS]

SICK!

[millerladino]

beautiful

[RM250crosser]

wow nice filming job

[2BarEG]

thats fuckin cool...

[venxxxxx]

they filmed it just as they film you while you were in your mom's stomach using ultrasound. Bet this was an ultrasonic video cam.

[WeedPatch71]

@venxxxxx I bet it wasn't. You wouldn't see color in ultrasound for one thing, nor would it be as crystal clear as this is.

[kevn33]

this looks FAKE the more i watch it.

[WeedPatch71]

@kevn33 Then stop watching it.

[thrunobulax1]

awesome. How the fuck you get a camera and light to work in that environment I'm fucked if I know:-)

[luisgamez8705]

how the hell did you get a camera in there!!??



[kingvic97]

@luisgamez8705 leprechaun

[lilslawz]

one of the coolest vids ive seen in a while.

[73sebrougham]

you can advance just a tad bit more!

[limppimento55]

Imagine how many times this event has happened and will happen in the history of mankind. Trillions of times in a blink of an eye times hundreds of years or more.

[Turkish42]

how the hell did they film this

[greenmarine5]

@Turkish42 just like a colonoscopy...instead of going in threw the anus they go in threw the exauhst...??? I have no Idea

[smackface6]

This is my porn

[elr456]

This is freaking cool. How is this even able to be recorded?

[gattosub]

OK. I'd like to enter the conversation here. Some years ago, I witness an experiment on a ultra high speed movie. A quartz type lens was made and inserted into a machine hole into a combustion chambers. The same type of camera was used that also catched bullets in flight. It's an amazing process.

[Laxpowertoo]

A very little man filmed it

[driveinshowbunnik]

how the fuck did you filmed this :O

[tttigggerrr1974]

Love it thank u...

[agoniesfury]

i love this!

[csgtfaught]

awesome

[jamesdond1]

Briggs, I could also send you links to several SAE studies which show the same thing. We have failed to improve efficiency for many reasons. We tax the productive and the efficient in our society... The US government now owns the biggest automotive company in the world. Their Volt is a flop. Sold only 281 in Feb. We are using an engine patented in 1862 in our cars, no wonder they waste 4 out of every 5 gallons burned. Is that what you mean by staying with the times?

[jamesdond1]

Briggs, I know you dream of automobiles that are 35% efficent....... but this is the truth..."Modern gasoline engines have an average efficiency of about 18% to 20% when used to power a car. In other words, of the total heat energy of gasoline, about 80% is ejected as heat from the exhaust, as mechanical sound energy, or consumed by the motor (friction, air turbulence, heat through the cylinder walls or cylinder head, and work used to turn engine equipment." see engine efficency, wikipedia

[Pronemezis]

This is soo cool !!:DD Nice vid!

[jamesdond1]

Briggs, Yes, real It also shows the many problems that still exist in our automobile engines today, which are still only about 20% efficient. You can see that the flame front seems to flash on and off around the wetted area of the intake valve, you will also note that combustion is still going on after the exhaust valve is open, big waste. Piston dynamics caused by the crank is the reason behind many of these problems. If you're 16 maybe you can invent a better engine. Keep up your study

[briggsquantum]

@jamesdond1 I'm 55 pops - good guess on your part. If you had bothered to read any of the previous posts you'd know that, and also why I consider the video a fake. You might also consider the discussion is about whether or not the video is a fake, not inventing better engines.

By the way turbo-charged diesels average 40% thermal efficiency, the largest Wartsila marine diesels are now 50%, and automotive gasoline engines run around 35%. You need to stay with the times.

[jamesdond1]

@briggsquantum It was your go bang your sister comment, made me think you were 16. I assure you that this is a real video. I worked with Professor Oppenheim at UC Berkeley on lab engines with high speed photography. You 're a mechanic, right. If you want to educate yourself sign up with the SAE and start reading some of Toni Oppenheim’s many papers on combustion. Then make you points. Even at 55 you can contribute to improving engine technology. We need to make things better...

[SOCKCOCK1]

I'm actually very impressed.

[bkunal88]

do u have same video for diesel engine ??

if yes pl. post here !!!

BTW good work

[tomview1]

Fake or real - who cares - this is a good tool for education.

[PrestonWolff09]

this is a pretty sweet video. i wonder how they caught it on film

[ubershot33]

@PrestonWolff09 They drilled out a small hole near the top of the engine, put a camera in and sealed the hole where the camera is. taped 4 strokes and put it up on youtube

[briggsquantum]

@ubershot33 So you actually know how the hole was drilled huh? I doubt it. You don't know shit. Nice that the lighting in the cylinder is so good when there is no flame.  Convenient. Of course it's a fake, and you and everyone else it seems swallowed it hook, line, and sinker.

Fail.

1164 people don't have a clue.

[ubershot33]

@briggsquantum wow you know nothing, there is a flame if you watch it from 0:12 to 18. you obviously have no common sense. do you really think and engine on the combustion stroke SPITS FIRE out? no, the engine pre mix's the gas and air and shoots it in at 0:01. the flame is big enough to push a piston carrying your ass around. and plus this is real, why would you go through all that trouble in building a fake set to tape this master piece when you could drill a hole in an engine and tape in slow

[briggsquantum]

@ubershot33 First of all there is no "combustion" stroke. Intake, compression, power, exhaust. Second I was trying to explain that there is too much light ( like for photography) during the intake and compression strokes, at which time the cylinder should be dark. Third, the piston is driven down by the expansion of gases due to heat, not by the "flame". Lastly, I've built more engines, for automotive, marine, aviation, and recreational vehicles, than you've had hot lunches.

[deetdadeet08]

@briggsquantum im on your side, guy.. hes obviously a ignorant douche who thinks he knows everything because he drives a Civic with 90 mil horsepower

[ubershot33]

@briggsquantum the camera has a built in light on it. look at a blackberry it has a camera and a small led light under it. same priniciple. and i know its called the power stroke. i just thought you were some little kid who knows shit about that. im 16, you sound older, 55 to be exact, i know that is what happened because at my high school we saw this video and tryed it with a special camera my teacher had for going in to the engine, it was cool to see the strokes.

[pancakewafflebacon]

@briggsquantum ok, then. how about YOU tell us all how they did it

[kantbecaught]

@briggsquantum ya your a fuckin moron, ever hear of a light? dipshit

[briggsquantum]

@kantbecaught Well first of all you must have meant "you're" meaning " you are" rather than the possessive "your". And the last word should have been capitalized with a period following. Perhaps you are white trash? If your neighbor lives in a tin-walled trailer, then you should consider the possibility.

As to the light theory, have you noticed that the reflection on the back wall of the combustion chamber does not change during the power stroke? I thought not. Go bang your sister.

[kantbecaught]

@briggsquantum Well first off I'm not too worried about proper grammar whilst making a simple comment on youtube. Second, you're an asshole, theres not any chance that you could no anything about me. So go ahead and keep being a pretentious little bitch, it's not gonna get you anywhere in life. And don't try to act proper, especially if you add the final little saying of "go bang your sister" really classy faggot!

[GodlessMartyr666]

@PrestonWolff09 pinhole camera, kinda like an endoscopy ;)

[chrisvarns]

@PrestonWolff09 with a camera. sorry, i had to.

[tenjinnim]

@PrestonWolff09 1. you will need a small camera that will fit in the cylinder block.

2. camera must withstand immense pressure

3. camera must withstand heat

4. camera must by sturdy.

[johns0791]

Learn your 4-stroke theory before commenting people. Exhaust on left, intake on right. Atomized fuel from injector sprayed on backside of valve to improve atomization is what you see. Notice how there is a slight lag between ignition and the start of combustion and the exhaust valve is opening before combustion is complete.

[briggsquantum]

Fake. Stoichiometric gasoline/air mixture is invisible, and the flame front doesn't propagate properly. Nice try.. Thumbs down

[Kentdaniel91]

Amazing :D

[hynykeko]

... brakuje wydechu, jest tylko poczatek otwierania zaworu wydechu - ale poza tym SUPER.

[rb26capri]

car porn

[DarioCrm]

Looks like the video is playing backwards. The inlet valve appears to be the left one.

[meda789]

@DarioCrm so wat?

[panhardrod]

@picmario well of course this engine has a hole in it for the camera which isnt going to help combustion

[millatym04]

So f'ing cool!

[theevilmeister]

I'm hard

[suzuki307]

Fucking awsome

[Hansibuwi]

super geiles Video +5***** von mir

[twistedyogert]

What kind of engine is this. 50cc 500cc 1500cc

[KendamaChris92]

i thought it was the bottom of a space ship landing and going back up.....

[MrAlanGNR]

este video es una mentira ¿¿¿¿como puede ser que la mescla de la admicion entre con tanta precion a el cilindro??? ni siquiera con el turvo mas potente se puede lograr semejante comprecion

PD:no ecciste ningun material transparente que soporte una expancion de ese tipo, puede haber hasta una tonelada por cm2 y mas de 5000 cª

[Uunster]

why does it skip when the exhust valve opens? i wanna see the whole cycle

[pmgodfrey]

@Uunster

it's a short clip running just 19 seconds, but looped 4 times.

[panzerveps]

@Uunster They had to replace the cameraman for each take...

[5ky5tr1d3r]

@Uunster because there is nothing you missed...it's a petrol engine,so it doesn't have black power smoke and things :) You'd just see valve going back and forth wasting precious 0.2 secs of lifetime :)

[Theravhard]

wicked fucking sick!!! BUT how was the camera inserted !??:(

[ACHEESEDANISH00]

@Theravhard thats what she said

[jersthecool]

Damn that's amazing how fast this actually happens at like 5k rpm insane!

[steis91]

@jersthecool think about the formula 1 which goes at 18k rpms :D huuuuuuge engine work :D

[jersthecool]

@steis91 Yeah wow lol I couldn't even imagine!

[Texassince1836]

cool, the little numbers are degrees till tdc(theres 720 degrees in a 4 stroke cycle)

[Texassince1836]

what kind of engine is it? it looks alot like my briggs and stratton 18.5 horse. theres no way thas a car engine, too low of compression, too little spark advance/gap, and its running rich(orange flame). this motor would fail smog if it were an automobile engine

[dmsmhic]

@Texassince1836 It looks more like the 22 horse.

[aaronzack14]

if you think about it, an engine is like high speed sex

[bogart286]

what people dont realize is that this happens multiple times per second in each cylinder. incredible footage. kudos to whoever got this footage! XboXd83 _ I second that statement!

[beluga420]

wow. I wonder how much thousands of dollar this camera is worth to be able to catch over 1000 fps... wow.

[bseriesus]

A new found respect for the internal combustion engine.

[janclint2004]

8 gays dislikes the video

[toyotapickup94]

@janclint2004 why does it make them gay? your a dumbass

[mikedsm12]

@toyotapickup94 word,

[MUSTANGMAN50LX]

that was fucking AWESOME!!! thanks i always knowed what was going on in there but i always wanted to see

[mexalkid]

I always wanted to know how this look thanks alot

[DevinL16]

thats fucking cool....slowest idle ive ever seen. JOKES!

[CuzPBz]

how was this camera setup,

[Shumpy1980]

Great!! I've never seen like this before.

[Shumpy1980]

Great!! I've never seen like this.

[zeppelin67637]

been building engines off and on for 15 years. Always tried to imagine, whats going on inside the cylinder of a running engine. It's absolutely amazing to be able to actually seeee it. Sometimes I just love technology.

[crazywaters]

A hole is drilled at the side of the cylinder head, then covered with a pyrex glass lens to protect the cable of a "snake" (fiber optic cable used in laparoscopic surgery) attached to an external hi-speed camera. now you all know how its done.

[MrTane23]

@crazywaters simple in therory....

[scofield669]

amazing!!!

[sponge111111]

brilliant, 

[ataymood]

wow.. i always wanted to see what really happens inside the cylinder..

now i knew.. thnx for the vid man....

[xboxd83]

this to me is equivalent to watching the moon landing.

[scofield669]

@xboxd83 damn right

[gq4101]

@xboxd83 I fully understand, or even the Saturn 5 taking off.

[odinsragess]

@xboxd83 LOL true! I always wanted to know what the violent explosions in an engine looked like. 

[mt12684]

@xboxd83 i could not have said it better myself

[legendofcraig]

If an engine idles at 1k rpm, i dont see anything moving at least 100 rpm in this...

[ClearSkyTMD]

@legendofcraig ever thought of maybe it was filmed with a high frame per second camera and then slowed down? Well, in this case it's so.

[tatanoski666]

niceeee looks like the intake is a bit of a hurry looks like a tornado entering

[peepsdayz]

6 women watch the video

[graikas]

@peepsdayz hahahahahaha good one! :)

[richboytyson]

@peepsdayz eight women now

[ganja4twee]

@peepsdayz 8

[RGVCripted]

@peepsdayz

The word is spreading, nine on my count haha

[myo247]

@peepsdayz 4 FILLES EN PLUS ON REGARDER CETTE VIDÉO

[thunderaceer]

@peepsdayz actually 11 right now escaped from the kitchen

[TrueBlueEG8]

@peepsdayz twice!

[jmecrg]

low compression motor not fuel injected

[samtheboer]

@jmecrg this is a petrol engine (spark plug). Older petrol engines were not injected directly into the cylinder, but rather in the inlet manifold or right behind the inlet valve. Judging by the amount of mist being drawn into the cylinder, i'd say its just behind the inlet valve in this instance.

[jmecrg]

@samtheboer basicly thats what said ......all the petrol sparkplug blah blah is obvious...........

[exportbhp]

I watched all sorts of videos, as we all have on you tube, but that is f**kin cool. Ill die happy now.

[SecuritySteve]

That engine is pinging, it detonated before TDC

[SecuritySteve]

Which could explain the hole in the piston on the right hand side at 10-12 seconds

[amayami]

@SecuritySteve Nearly every gas engine fires some degrees before TDC, especially under heavy vacuum, I.E. while cruising at low load.

[deafdude6]

@SecuritySteve not really. its should ignition right little before tdc which called retarded on ignition timing 12* degree retarded. very common for idling.

correct me if im worng

[trkklr77]

@deafdude6 retarding is decreasing the amount of advance/btdc, a "retarded" motor would use a firing time of x* after tdc. the act of retarding the timing you turnign the dist back to go from 18 btdc to 12*btdc.

your dist only continues to advance the fireing/ignition btdc as the rpm increase.

ie you may only run 4-12* at idle but most motors run anywhere from 20-36*btdc @3000+. things like octane and compresion ratio will dictate exactly how much you will require.

[nmann15]

That was the second coolest thing I've ever seen. And btw, How the hell did they film this?

[1brannon10]

this is wicked

[TehTurboKinetics]

Man, even pondering about the physics of this fascinates me... But actually getting to see it in action? Now that's another story.

[mihou2]

Shit, 6 dislikes?!

[frankyw729]

that was by far the coolest thing i've ever seen. and i have 4 testicals hahaha

[chargerfish1]

howd they get a fkin camera in ther

[iriddell1]

@chargerfish1 im guessing they bored into the chamber and sealed the hole with the boroscope camera. really impressive huh?!

[chargerfish1]

@iriddell1 yea

[dodgedart74]

its like an argument going on inside the engine, the piston is pissed, once the intake valve(friend of the spark) has his input into the argument, the piston comes back and says "wha!?'' land the spark quickly says "prick" and the piston gets all pissed off all over again and storms away, and then the exhaust valve who looks the best isnt high on hydrocarbons all day, comes in and reassures the piston and the spark, and cleans up the mess form the fight, then intake comes back again says "well"

[steelstrings1312]

@dodgedart74 lmaooooooooo!!!!!

[vibeflyer]

Suck, Squeeze, Bang, Blow ........wink wink

[videman21]

how the hell do you film this?

[johndeeremudder]

i like that 

[likoly02]

The video is skipping the most interesting part, the overlap sequence, gggggg

[atruepretense]

Holy fucking shit. Now i've seen my car visually working :P

[twisteddragyn]

That's just awesome, you can even see the valves spinning in their seats, that's something you could only show like this.

And really who cares if it's not the full exhaust cycle? Doesn't make it any less awesome to the rest of us. Durrhurr FACT

[shinmo117]

wow, the intake stroke is AMAZING!!

[grippinoak010]

nice

[iliyas10]

wow thats nice



[nuke00]

sick

[tunastrike11]

pretty amazing

[cvhdrd]

how did they install the camera and where?? amazing!!

[Drivinfast247 <]

It never shows the exhaust stroke.
