inside an engine

[GetPatriotized]

Centennial college!

[GUYANESEGT]

wow that's one boss of a camera to survive in there

[superelli2007]

awesome!!!

[roger1anderson]

thats probably a larger marine diesel or a powerplant diesel

[caddy52]

@roger1anderson Its got a spark plug,so its not a diesel.

[okyat]

@caddy52 so i didnt get it, diesel engines dont have spark plugs? then how are going to ignite?

[asdglasfk]

@okyat diesel ignites by compression

[metalworshiper123]

@okyat

diesel engines compress the fuel so amazingly hard, that it heats up and ignites. if you've ever seen inside a diesel motor, you will see how much of a gap the piston has from the valve..it's almost a hair strand

[carpetmonk]

alcohol fuel maybe?

[nzoomed]

WOW! thats amazing!

Never thought it would be possible to film, i wonder how they got a camera inside and have a video connection etc?

Camera would have to be very heat resistant and small as to clear the piston.

[olegario39]

this is the equivalent to the moon landing

[droid873]

That's bad ass!! how did. You do it?

[bALLjUICE100]

I bet this is a hemi engine couz the spark plugs on top :)

[mihax209]

what is this? about 9999999 fps?

[AzNtacoSAUCE]

to me, this is the equivalent of watching neil armstrong walk on the moon. thanks for the upload!

[ashybashywashy]

SUCK, SQEEZE, BANG, BLOW

[1unevensurface]

lemme just say that this is one bad ass little camera

[simpleassassin08]

this is a four stoke engine

1 intake

2 compress

3 combustion

4 exhaust

[maschinenmeister]

that's incredible

[vtownHduece]

vtec!!

[greatwhitenorth112]

@vtownHduece V-CRAP

[JanAshleyTisdaleFan]

very cool!!!!!!!

[cakebx]

Wow! Nice work!

[michaszek12]

to jest slow motion ten tłok powinien dużo szybciej chodzić w gore i w dół

[makoman1860]

Keep up the guessing guys, maybe somone will figure it out :)

[rcbuggyracingya]

this video is so slow motion!

[SuckeroftheYear]

i like this view...

[NatosREekeiEinai]

it only show 2 strokes of 4

[mxinpvr]

It shows 4,,,,Admission of Fuel, Compression, Explosion and Emission......then it repeats again

[joejedlicka]

It clearly shows intake, compression, power, and some of the exhaust stroke.

[oaklandpinoy]

Maybe it was captured during the start up.

[TVRFan11]

That was friggin cool.

[bakinblack1]

4 STROKE THEORY!!!! hurraaayy

[Brunominasi]

nice, always wanted to know how it works in real...

[wdrumheller2000]

I think this is about 500 pictures, each taken at slightly later in the cycle, while the engine was running, therefore giving the illusion of slow motion.

[digosantista]

You just describe what a slow-motion is...

[vivadangermouse]

Inclined to agree with you there.

[IANBUFFTON]

thats all video is. a series of pictures put together

[FORDGTFANATIC]

isnt that what a camera is? cameras use fpm (frames per second) or pictures per second basically

[wdrumheller2000]

I don't think this is slow-motion.

I think this is about 500 pictures, each taken at slightly later in the cycle, while the engine was running, therefore giving the illusion of slow motion.

For instance, a way to get the camera to fire would be to use the spark as the signal to snap the picture. Then, while the engine is running, slow down the timing a bit, and then take a series of pictures as you slowly increase the timing of the engine.

The result?

This video.

I may be wrong.

[IRONSKENG]

you could be right. you notice the camera moves very slightly but in a way that it looks as if it wasn't taken in one shot..

but if the engine was idling at 1000 rpm one of these full rotations would be over 0.06 of a second (60 seconds/1000 rpm).. so there is no reason it couldn't have been recorded in slow motion?

[dubvipers]

the engine has vibrations.

[cheetoh5]

That would be incredibly difficult to engineer to that precision when you could just use a professional high speed camera. Another question though would be how they got enough light in there to see what was happening

[geonerd]

You are almost certainly right. Look at the intake charge, spark arc, and flame fronts. All these moving subjects jump about violently from frame to frame. The effect is similar to jQDjJRYmeWg

[Manlezl]

awesome!!!

[clpx1]

Looks like a 4 valve cylinder...maybe a cycle engine?

[sunwatcher85]

Two valves visible - one intake and one exhaust. Why do you think there are 4 valves?

[enterBJ40]

this show us all how  violent the engine interior'scan be...imagine thisbeen repeated infinite times...a lot wear!!!

[tMattLZ]

cool i would have guesed that the explosion would be more on the exaust side...

[2yungtone2]

...wat? mor on the exhaust side?

[jjson89]

why would it be on the exhaust side??????? More oxygen is concentrated at the inlet valve than the exhaust valve after it has just closed..... and any combustion requires a presence of O2, therefore the explosion is more on the intake side

[1993z32]

sweet! would love to see how it would look inside the motor of a car on 30lbs of boost :)

[mikrass90]

wow!

[halo23602007]

siikkkk

[dragdrower]

cool

[Astromic]

that's what youtube should be filled with,,,thanks' for the upload,,,

[Sheepiesaurus]

Its a shame they didn't include the exaust stroke.

[ellis987654321]

that is so sick

[MetalicB0x]

this is what i imagine hell would look like, crazy

[asdglasfk]

just a note: i did not make this video, i have no idea who did and how they did it. so please credit the real author :)

thanks

[wadnarancs00]

nice vid and VERY hard to make.. what a preasure omg

[aidanhd]

how the hell did u get a camera inside th cylinder???

[matt100877]

welcome to the four stroke cycle!

[Nza420]

drat! ran out of film right at the end of the cycle.. ah well, still awesome!

[CleanSpoon]

amazing machine

[dragongoff]

Very informative and worth the effort you went through to get it done...

[RICbass78]

woah.

[shaz4real]

thats HEavy

[killermess]

OMG cool!!!

[WaR1oCk666]

at full rmp in my car it does that 9000 times a minuite!

WOW

[joejedlicka]

If I may interject, at 9000 rpm, it does this 4500 times per cylinder per minute, as it takes 2 crankshaft revolutions to complete the 4 cycle principle. If it was a 2 stroke engine, then your calculation would apply on a per cylinder basis, i.e. a 2 cylinder 2 cycle engine would have 18,000 complete combustion cycles at 9000 rpm.

[naut1648]

thats a very sweet video!

[cosast54]

I always wanted to see taht! thanks

[gasman7777]

thats incrediable. i always wondered what it was like inside an engine running like that.

[ControlledExplosions]

That's incredible! I wish they showed the complete cycle, and then maybe it running normal speed

[kjetilvh]

this is the complete cycle

[ControlledExplosions]

Damn! That's incredible!!

[DyingToLive6280]

how in the world....?!

[segreylapa]

isit in slow motion?

[stevenjaypark]

Being that that piston moves up and down about 50 times a second on average, yeah, I'd say it in slow motion quite a bit. Genius.

[sleepovernightmare]

No its fastened up, moron

[andrewhakim]

acctually its slowed down lol

[ejepeje]

lol

[Hertstunedriders]

To clarify this

Its a very new engine

You can clearly see the fuel being entered

And the spark igniting

Its obvoiusly a 4 stoke due to valves

And the piston rev

Amazing to say the least

[rcorona127]

I guess that cam got burned instantly... that explains why the vid is cut just a moment after the explosion

[asdglasfk]

actually, you can clearly see:

- the explosion

- the piston being pushed down

- the exhaust valve opening

- the exhause fumes going out

[rcorona127]

pay attention to the exhaust valve when its getting back... that moment the video es cut and the cycle begins again, i mean, u never see the exhaust valve closing

[asdglasfk]

i don't need to, i'm happy with what i see :)

i have no idea if the camera was destroyed, but since the image is crisp all the time, i think the camera is fine.

[rcorona127]

haha it's amazing anyway...

[rodjownsu]

Yeh it definately is amazing however the camer is ok. You can see it survives completely fine after the combustion cycle and they have chosen to not show 1 complete cycle for whatever reason

[TJScott2012]

i think that is just where the camera shuts off and they are just replaying it.

[riflemanjim]

@rcorona127 I don't think it's a real engine theres no carbon and no spark plug discoloration. In a real engine if the air/fuel burned reddish orange like in this photo there would be carbon all over the chamber and exhaust valve face. The flame frong doesnt seem to start from the spark plug outward either.

[krhall78]

I'm with otto xD

Fuel burns harder as a vapour than a liquid. Rudolf diesel was luck because his first prototype engine nearly killed him. Then he invested very badly getting heavily in debt, he was never oficially given the true recognition he deserved.

[dieselscience]

THANK YOU! Nicolaus Otto. When we gear heads die we are all going to the Great Reward beer garden to have Bier und Bratwurst with Otto and Diesel.

[Lokura135]

is that the air going in?

where is the spray of the fuel injector?

[sunnyjason]

the fuel injectors are in manfold. the air goes into cylenders are pre-mixed.

[rodjownsu]

This appears to be an older style car with a carbeurettor so the fuel is mixed with the air and not injected like newer style cars are.

[asdglasfk]

only direct injection engines inject (doh) the fuel directly into the cylinder chamber, and this system is VERY new.

all "older" injection systems blow the fuel into the intake, before the valve.

[Lokura135]

when all the exhaust combustion goes into the manifold, how does this create "power" or how is it transfered to the wheels? please help im trying to learn about cars I love them

[dieselscience]

Power is transfered to the piston just after the spark and before the exhaust valve (left) opens. You are seeing the video a bit chopped up, it's not quite the entire cycle.

[eikitpovelniu]

absolutely incredible!

I always wondered to see the video like that.

Thanks who made this!

[mrjustin5]

That is absolutely amazing. I have never seen real footage of a combustion chamber in operation. The camera shakes around violently, looks turbulent in there. Super slow motion and you see the fuel/air mixture and the spark plug fire for quite awhile (since its slo-mo) and then the flame erupts and burns up everything. Incredible!

[fatboy143]

thats the most beautiful thing i have ever seen..

[lampdug]

a agree that is beautiful

[longredcoat]

wow thats hot(the combustion chamber)lol

wot did material is the camera made of

[jesuschristbitch]

realy cool, i always wondered what it looked like in a moving engine.

[boon4376]

heat resistant 1000 fps cam

[xDRAN0x]

beautiful !

[Slapsider]

how the hell did they get the camera in there!!
