micro camera inside a four stroke engine

[mudaphucker]

Stunning

[MegaEpicWaffles]

this is pretty cool

[DREX031]

Whats with the intake valve opening just after TDC? lol

[moosiah]

I saw these pix yrs ago. they were taken during ww2. they used a quartz window into a test engine. the engine was spun up to speed and fired once, maybe twice. the test engine was a cylinder from a aircraft radial engine.. other clips show detonation and preignion burn patterns.

[morominaolenmina]

who that camera can be there inside? there is very hot and i think that any camera would damaged there! how this can be possible! tell mee please!

[nitroman365]

I liked the video. Im not sure if everyone who is commenting watched the same one. I didn't want see any "faggots" in it like most have posted.

[fd5848517]

whats the name of the camera??? PLEASE TELL ME

[OregonDARRYL]

@fd5848517 George.

[colacitrusmtn]

Respond to this video... The suction is a lie. Squeeze blow to the throttle shaft with my sweet lies. There is no vacuum, earth is a low pressure zone. Suctions is a lie! The cake is a lie.

[metalworshiper123]

@colacitrusmtn

wow man! thank you so much for your knowledge? did you learn that yourself or did you just copy the guy in the top rated comments? fuckhead....

[colacitrusmtn]

@metalworshiper123 no, but did an australian just open his cocksucker in my direction? listen crocodile dundee, why don't you ease up off the faggotry, ok? You're off the fucking charts dipshit. fake british crocodile dundee motherfuck.

[metalworshiper123]

@colacitrusmtn

"faggotry"....grow up poof

[colacitrusmtn]

@fd5848517 Woolybooly.

[colacitrusmtn]

@fd5848517 Wilhelm.

[justgr6]

And yes. Suction is lies. Those who can't do.... Teach! Some teachers are the stupidest people I have ever met!

[justgr6]

Oh and suck squeeze bang blow is incorrect... To an extent. I already explained the suck part next is the bang. Again, untrue. It's not an explosion nor is it a bang. It's a controlled burn. Flame propagation would be the correct term. One fuel molecule at a time burns and releases its energy into the cylinder.

[justgr6]

@pomeroy. Yup! Suction is all lies. LOl. Can't believe this was posted almost two years ago.

[losipoop]

that looks retarded

[rapidotorpedo]

dude what camera is tht?

[Skid00everest340]

ah thats kids stuff put a camera inside a scania 14 litre turbo diesel v8 from 1970 =)

[biffula]

I figured there would be much more flame than that. Interesting.

[AndyRoddick969]

@biffula maybe this is in a 4 Cylinder Ford Fiesta. its probably different if it were in a Formula 1 Car.

[BSTRDASH]

if only there was sound.

[madnessknight2010]

@BSTRDASH it would destroy the mic do to high presure in there

[coastguard1996]

is this in slow mode

[AOKONE]

@coastguard1996, no.. this is the actual pace of an 4 stroke engine at idle.

[madnessknight2010]

@AOKONE not really.... slowed vary much

[AOKONE]

@madnessknight2010, i was sarcastic or atlest trying.

[mackat4ck]

@AOKONE lol!

[36567brad]

@AOKONE hahaha yup its about 3 rpms

[moptim]

the engine seems to be fuel injected to my eye?

[tutankhatenll]

That's really rather beautiful and elegant.

[renault7814s]

de nokkens as drijft de stootstangen aan van de tuimelaars en de tuimelaars open de kleppen. En de krukas laat het vliegwiel draaien en de koppeling

[Zoefzoef24]

@renault7814s oh really?

[drebinable]

fake

[BiohazardDingleberry]

your an idiot

[fnaguitarplayer9]

i would like to see a video just like this but with a flathead ( L Head ) engine. that would be neat haha.

[pjwithbread8]

still dont understand relly how the piston just going on its rod and spining making it go up and down makes those 2 valves open. :/

[localfuckingized]

The crank is connected to the camshaft, which opens the valves.

[Toasty504]

compression?! maybe the crankshaft.... dude redo that question.... i dont even know how to read that

[rogerbodger33]

the pistons are connected to the crankshaft which rotates, the cams operate the valuse and the valves are controlled by the camshaft which gets its rotationaly movement from the crankshaft

[JMDDE]

the piston doesn't open the valves, thats what the camshaft does, im sure you can find something on it here

[hondamannen1]

any one that have video like this on o 2-stroke motor ?

[Toasty504]

search>  howstuffworks in the youtube search thingy.. they have a video of it

[tinkywinky19]

that camera must be expensive its like 1000 degrees in there!

[Zeriouznez]

It's actually 2500 to 3000 degrees, so that camera must've been very expensive :P

[musclekid13]

@tinkywinky19 Hotter than that.

[hxcpunkforlife]

@tinkywinky19 its 3000º wen the fire is burning

[Kingjamesif]

Suck squeeze bang blow folks it's all you need to know

[nikoleman]

cool, that must be some expensive equipment so small and able to record at such high fps

[marsCubed]

It doesn't have to record at high fps, the timing can be adjusted to progress through the engine cycle. provided the timing is accurate this need not be done for every revolution of the engine.

A camera need not be to expensive or small either, optical fibre could be used to get the image to a camera and provide light, passed through the engine head, perhaps through a gasket. I dunno anything about the video, but is should be relatively simple to do oneself with a little effort.

[justgr6]

Due to the fact that atmospheric pressure (14.7psi) is higher, it "pushes" the mixture into the cylinder to equalize the pressure difference. A vaccuum cleaner works the same way. A low pressure zone is created inside the vaccuum and the high pressure will want to push its way in to equalize itself.

[justgr6]

Well kiddies, pull up a chair and wrap your head around this.  Nothing in ths world is "sucked" or "vacuumed". Everything is pushed. Jared, you are right to an extent. The mixture doesn't just "fall" into the cylinder. It is pushed. Everything in this world operates within the realms of high and low pressure. When the piston is on the downward (intake) stroke, it creates a low pressure zone within the cylinder.

[Evolution2810]

@justgr6 which the low pressure causes a vacuum and sucks the mixture in

[bieli0]

@justgr6 kinda like there's no such thing as "cold" ......"cold" is the absence of heat... a thermometer measures heat only...

[pomeroy600287]

@justgr6

'Suction' is Lies-to-children.

[79fordblake]

@justgr6, so your saying when a engine is at idle and the throttle plates of a carb are closed there is no vacuum created when the piston is going down? Thats BS. If no kind of pressure is created then why can you feel your hand being pulled on it you get it to close to the intake?

[Learnthethingsido]

@79fordblake You are right. Because When an Engine is at Idle the throttle plate is Opened a little bit Maybee 1\10th of an Inch. And when you Turn up an Idle Screw it opens that Throttle late a little more.

[dridley11]

@justgr6 Humpty-Dumpty was pushed...Your theory is solid.

[Cursed5soul]

@justgr6 i'm just wondering... wouldn't a low pressure zone in comparison to a normal or high pressure zone be considered a vacuum?

[DrGoodwrench64]

@Cursed5soul

***DING***-***DING***-***DING*­**

We Have a WINNER!!!

Someone give that man a Cigar!

You are absolutely correct.

It's all relative. Vacuum is relative to Pressure in a sealed system.

Outside of a sealed system, High & Low pressures are relative to TEMPERATURE & HUMIDITY.

And FYI, this video is totally FAKE. IF you could put a camera in a second spark-plug hole and it survives past startup, the lens would turn completely black from exhaust soot in just 2 revs.

Still a good demo.

[EmyY2J]

thats so cool....but that happents verry verry fast.....:P

[jared4747]

Then i would say you are wrong. The air fuel mixture just doesent fall in the cylinder when the intake valve opens. When the piston travels down it helps pull it into the cylinder. Have you ever took a spark plug out and stick your finger over the hole and rotate and engine you feel it try and pull your finger in. Also it will push your finger out on the compression stroke. Make sense?

[jared4747]

Hey 94EglVisionTSI, When the piston is at TDC and starts go travel down the intake valve opens when the piston is travel down you have vacume that helps draw air fuel. Both valves close for comp. stroke you get ign. blows the piston back down. When the piston is at BDC the exhaust valve opens when the piston is traveling up it pushes the burnt gases out. Then the whole cycle starts over.

That was just a bit more detail but brief because im running out of room. Hope that helps.

[justgr6]

What would you say if I said there is no such thing as a vacuum????

[naxps]

i would say there is no such thing as suction but there is such thing as a vacuum.

[sausageslaps]

i would say you are full of shit, i have a filter queen in my closet as we speak, cleans the carpets twice a week if they need it or not

[Daeonh22ek]

Actually some DIESEL 2 stroke engine have Valve .... check out Detroit diesel 4-71, 6v 53 etc .. these have intake ports and exhaust valve they are Mecanical DIRECT injection engine ...Using a Blower or a combination or Blower/turbo to get the air inside the Comb. Cham. and to help spool it out ...just wanna let you know :)

[supermower117]

that is awsome

sumething ive always wanted to see

[circutracer150]

Didn't seem like a very efficient burn...

Great vid though..

What do you think the results would be in using E85 Ethanol in a 2 stroke?

[mashhead1000]

how can you tell that it didnt seem like an efficent burn? are you some kind of firestarter or something?

[circutracer150]

Technical analyst and mechanical engineer for BMW actually.

[CTPa10]

Soooo cool awesome video

[Veritaslol]

Sorry at BDC the intake port is open and the exhaust port is closed

[tmaxxarethebest]

nice im gessing it was acherly running as well :S

[94EglVisionTSI]

thats way kool..wheres the compression stroke???seems like a 2 cycle

[tmaxxarethebest]

he cut that bit out cos it would take to long on slow mo thingy

[Veritaslol]

you can also tell its a four stroke because it has valves

[94EglVisionTSI]

Huh? That don't make sense

[94EglVisionTSI]

2-strokes have valves also..lol

[Veritaslol]

No they dont thats why that dont valve bounce, i think i would know i am a mechanic

[Veritaslol]

they dont have valves because the have "Intake" and "Exhaust" PORTS.

[Veritaslol]

Their is a compression stroke its just after the fresh air and fuel is drawn in, just before igniting and becoming the power stroke.

[94EglVisionTSI]

I see , i aint being a smart-ass cuz i tend to pride myself with my knowledge on the subject at hand, but how do the ports seal when theres ignition? or when the other port needs to be used?

[Veritaslol]

The 2-Stroke engine has a device on the intake port called a reed valve this is a valve which allows fuel to enter but does not allow fuel to return to the carburettor. The ports open and close by the operation/ position of the piston, as the piston moves up it uncovers the intake port and atmospheric pressure allows fresh fuel oil and air (unless its oil injected) to enter the crankcase of the engine, at the same time the fuel oil and air from the last cycle is being compressed and ignited

[Veritaslol]

once it has ignited at TDC (top dead center) the pistion starts to move down this is called a power stroke, as the pistion is moving down it opens the exhaust port and the burnt gases are removed from the cylinder as the pistion keeps moving down it compresses the Fuel oil and air in the crankcase this is called crankcase compression. as the pistion reaches BDC (bottom dead center)at this time both ports are closed, the fuel oil and air is moved through the transfer port (by pressure)

[94EglVisionTSI]

How can the exhaust gasses be pushed out when the piston is going down and creating a vacuum?

[Veritaslol]

moving it up into the cylinder. the pistion starts moving up and compressing the Fuel oil and air for the ignition. then the hole cycle starts again. this starts at the third comment down and moves up.

[Veritaslol]

the comment i posted starts at the third comment down and moves up.

[teamformsvacka]

cool movie !

Do you have a picture of the camera? must be a really small one ?

/ urban

[elmunxa]

very intersting i've never seen this before
